Vintage Costume Jewelry: How to Identify Trifari, Coro, Haskell, and Value Your Pieces

The Major American Makers of Vintage Costume Jewelry

The golden age of American costume jewelry was roughly 1935-1965, when the major design houses produced high-quality pieces that remain highly collectible today. Understanding who made what helps you quickly identify a piece's value range. **Trifari (1918-present, though the vintage era was 1930s-1970s)**: Founded by Gustavo Trifari, the company hired Alfred Philippe as chief designer from Cartier in 1930. Under Philippe, Trifari became known for its high-quality craftsmanship, inventive designs, and the 'Crown Trifari' mark. Specialties include: invisible-set stones (fur clips, rings), 'Jelly Belly' animal pins with Lucite bellies, holiday and figural designs, patriotic pieces during WWII. Key marks: - **KTF** (1930s) — from Philippe era, desirable - **Trifari** with or without crown (1938-1954) — the 'Crown Trifari' era is most valued - **Trifari** in script without crown (1954 onwards) — later pieces - **Philippe** marked pieces — designer-signed, premium value Value range: $30-$100 for common pieces, $200-$500 for nice Crown Trifari, $500-$5,000+ for Jelly Belly, Philippe-signed, or rare designs. **Coro (1902-1979)**: Massive producer (by 1940, Coro was the world's largest costume jewelry maker). Brands include Coro, Corocraft (their higher-end line), and Vendôme (their designer line from 1944). Specialties: duettes (pin that separates into two smaller pins), colorful figural pieces, floral designs, enamel work. Key marks: - **Coro** (basic line) — most common - **Corocraft** (higher quality) — sterling bases, better stones - **Vendôme** (designer line 1944-1979) — highest quality Coro - **Adolph Katz** (designer) — sometimes marked, premium Value range: $20-$75 for basic Coro, $75-$300 for Corocraft, $150-$1,000+ for Vendôme, $300-$3,000+ for signed duettes. **Miriam Haskell (1926-present, though vintage era 1930s-1981)**: The top-tier name in vintage costume jewelry. Haskell created intricate, elaborately-wired pieces featuring pearls, glass beads, rhinestones, and Japanese or Venetian glass. Her chief designer Frank Hess (1926-1960) defined the classic Haskell look. Larry Vrba and Robert Clark later continued the tradition. Key marks: - **Earlier pieces (pre-1948)**: unmarked or with oval plaque reading 'Miriam Haskell' - **Horseshoe-shaped Miriam Haskell mark** (1948+): most common vintage mark - **Unmarked Haskell**: many pre-1948 pieces have no mark but are identifiable by construction (hand-wired, distinctive materials) Value range: $150-$500 for small or common pieces, $500-$2,000 for signature Haskell necklaces and brooches, $2,000-$15,000+ for rare early or designer-signed pieces. Haskell is particularly valued in the current market — collector interest has been strong and sustained. **Weiss (1942-1970s)**: Albert Weiss established his company after leaving Coro. Known for high-quality rhinestone work — particularly Austrian crystal rhinestones and unusual stone colors. Weiss was often called 'the poor man's Harry Winston' for the quality of his stone selection. Key marks: **Weiss**, **Albert Weiss**, **AW** Value range: $40-$150 for common rhinestone pieces, $200-$500 for exceptional Weiss rhinestones, $500-$1,500 for rare or signed designs. The most famous Weiss pieces are Christmas tree brooches — a specific collector sub-category that has its own market. **Eisenberg (1914-present)**: Originally a fur dealer, the Eisenberg family began selling jewelry as buttons for their fur coats in the 1930s, then realized the jewelry was more popular than the furs. Known for oversized, ornate, highly-sparkling pieces with large stones. Particularly famous for 'Eisenberg Ice' rhinestone brooches. Key marks: - **Eisenberg Original** (1935-1945) — sterling base, earliest and most valuable - **Eisenberg** (1940s-1950s) — high quality - **Eisenberg Ice** (1950s-1970s) — clear rhinestones, heavier pieces - **Eisenberg Ice** in script (1970s+) Value range: $75-$250 for common pieces, $300-$800 for Eisenberg Original sterling, $500-$2,500+ for rare or designer Eisenberg pieces. **Schiaparelli (1927-1954 in jewelry)**: Elsa Schiaparelli's Parisian fashion house produced jewelry as accessories to her couture. Known for surrealist designs, unusual color combinations (particularly her 'shocking pink'), bold oversized pieces, and unusual materials (aurora borealis stones, lava rock, Bakelite). The Schiaparelli jewelry line in the US (1949-1954) produced highly collectible pieces. Key marks: **Schiaparelli** (basic), **SCHIAPARELLI** (different fonts for different eras) Value range: $150-$500 for common pieces, $500-$2,000 for classic Schiaparelli, $2,000-$10,000+ for rare surrealist or signature pieces. Schiaparelli is considered one of the top collector names and values have been steadily rising. **Other notable makers**: - **Reinad (1922-1955)**: produced for major brands, unmarked early pieces - **Mazer/Jomaz (1927-1981)**: high-quality designer pieces, Joseph Mazer distinctive designs - **Hobe (1887-present)**: long-running, strong mid-century designs - **Boucher (1937-1971)**: French-style elegance, pastel colors - **Sarah Coventry (1949-present)**: lower-end collectibles, mass-market - **Juliana (Delizza & Elster, 1947-1990)**: unmarked but identifiable by distinct 5-link construction - **Kramer (1943-1980)**: rhinestone pieces, Christian Dior licensed reproductions - **Napier (1875-1999)**: quality mid-market jewelry, silver-tone specialty Valued identifies maker marks from photos and cross-references against its database of 150+ costume jewelry makers with associated value ranges and era dating.

Reading Maker Marks and Dating Pieces

Maker marks are the primary way to identify and date vintage costume jewelry. Most pieces from the major makers have a mark somewhere, but finding and reading it requires systematic searching. **Where to look for marks**: **On pin/brooch backs**: the most common location. Look on the vertical pin stem, the back plate, or any flat area on the reverse. Marks can be stamped, engraved, or on an attached plaque. **On necklace clasps**: check both sides of the clasp and the connector beads nearest the clasp. Small marks can be easy to miss. **On bracelet clasps and links**: examine each link and the clasp mechanism. **On earring posts or clips**: the back of the clip or post. Marks on earrings are often smaller and harder to read. **On plaques**: some makers attached small metal plaques with their mark. These can be riveted, glued, or hung on chains. **Common mark types**: - **Impressed/stamped marks**: pressed into the metal with a stamp. Sharp, clear edges. - **Cast marks**: part of the original mold. Softer edges. - **Applied plaque marks**: separate piece of metal attached to the jewelry with the maker's name. - **Engraved marks**: cut into the metal by hand or machine. Often with other identifying text (patent numbers, country of origin). **Country of origin marks (dating clues)**: US tariff and customs regulations required country-of-origin marks on imports starting in 1891 (though costume jewelry was increasingly domestic production in the 20th century): - **'Pat. No. [number]'** — US patent number, searchable online for specific dates - **'PAT PEND' or 'PATENT PENDING'** — applied before patent issued - **'USA' or 'Made in USA'** — domestic US production - **No country mark** — usually US-made pre-1960s - **'Made in [country]'** — imported, varies by era and maker **Patent search**: if a piece is marked with a patent number, you can look it up on Google Patents or the USPTO database to date it exactly. Design patents were commonly used in jewelry to protect original designs. **Material marks**: Besides maker marks, jewelry may have material marks: - **'Sterling'** or **'925'** — sterling silver content (over 92.5% silver) - **'GF' or 'Gold Filled'** — gold layer bonded to base metal - **'RGP'** — rolled gold plate (thinner than gold filled) - **'14K' or '18K'** — gold karat (rare in costume jewelry) - **'GP' or 'Gold Plated'** — electroplated gold layer - **Unmarked**: typically base metal (zinc, brass, or pot metal) Sterling-based pieces command a premium over base metal pieces, even from the same maker in the same era. **Era-specific clues**: **1920s-1930s (Art Deco era)**: - Geometric designs, streamlined shapes - Chrome, marcasite, Bakelite plastics common - Strong contrast colors (black/red/white) - Figural motifs (Egyptian, oriental, flora) **1935-1945 (WWII era)**: - Sterling substitution for nickel (nickel was war-restricted) - Patriotic themes (American flags, V-for-victory, servicemen) - Sterling-based pieces more common - 'Sterling' or 'Sterling Silver' markings proliferated **1945-1955 (post-war)**: - Return to colorful, feminine designs - Lucite belly pieces (Jelly Bellies) peak era - Increased availability of Austrian crystals - Sterling gave way to white metal base for most makers **1955-1965 (mid-century modernism)**: - Larger, bolder pieces - More enamelwork - Aurora borealis stones (iridescent) very popular - Christmas tree brooches became a tradition **1965-1975 (late vintage)**: - Space-age designs - Mod geometrics - Psychedelic color combinations - Transitional era — some pieces straddle modern/vintage classification **Post-1975**: generally not considered 'vintage' by strict collectors yet, though this threshold moves over time. **Authentication considerations**: Unfortunately, reproduction pieces exist in the market. Warning signs: - **Impossibly perfect condition** for the claimed age - **Wrong mark for the era** (e.g., 'Miriam Haskell' in a font not used until later) - **Materials inconsistent with the era** (e.g., modern stainless steel in a piece claimed to be 1940s) - **Construction differences** (modern castings vs period stamping) - **Sellers with no track record** or unclear provenance For high-value pieces ($500+), consider professional authentication. Reputable authenticators include specific costume jewelry experts who publish reference books (Harrice Simons Miller, Roseanne Ettinger, Cherri Simonds). Valued cross-references maker marks, patent numbers, and era indicators from photos to provide dating and authentication confidence scores.

Materials and Construction: What Adds Value

Beyond the maker, specific materials and construction techniques drive value in vintage costume jewelry. **Stones (in approximate order of value impact)**: **Austrian crystal rhinestones** (particularly Swarovski from 1891+): highest-quality cut rhinestones. Notable for their precise cut, clarity, and brilliance. Swarovski-sourced stones are particularly valued. Identifying Austrian crystal: 8 facets or more (cheaper stones have fewer), precise geometric cut, consistent sparkle across all facets. **Art glass stones**: specifically Czech, Venetian, and Japanese glass stones from the mid-20th century. Distinctive colors (especially blues and greens), often hand-made. Haskell used high-quality art glass extensively. **Faux pearls**: quality varies enormously. Top-quality faux pearls (used by Haskell, some Trifari) have multiple coating layers and a weighty feel. Cheaper faux pearls are obviously plastic. Faux pearl quality can be tested by gently rubbing on teeth — real pearls feel gritty, glass faux feel smooth with slight weight, plastic feels warm and very light. **Cabochons (flat-back stones)**: often glass or resin, pressed flat with a rounded top. Classic in figural pieces (eyes of animal brooches, centerpieces of floral designs). **Rhinestones (clear/colored cut stones)**: the classic rhinestone look. Quality varies from Austrian crystal (high-end) to cheap pressed-glass stones. Color consistency and setting quality distinguish quality pieces. **Aurora borealis (AB) stones**: iridescent coating created in 1955 by Swarovski. Used extensively in late-vintage pieces (1955-1970s). Modern reproductions use AB stones too, so this alone doesn't date a piece. **Base metals (from most to least desirable)**: - **Sterling silver**: premium base. Used during WWII and for high-end pieces. Adds real silver value in addition to collector value. - **Gold-filled/Gold plate**: bonded or plated gold over base metal. Adds modest value. Marked 'GF' or 'GP'. - **White metal (nickel)**: common base for mid-century costume jewelry. Durable, takes plating well. - **Pot metal / zinc alloy**: cheaper base, prone to deterioration and discoloration. - **Japanned metal (black-coated)**: black enamel coating over base metal. Used for darkening metal in certain design aesthetics. **Construction techniques that add value**: **Hand-wiring**: Miriam Haskell and some Juliana pieces feature hand-wired construction — individual beads and stones wired together with fine brass wire. Time-consuming, produces distinctive flexible mesh effect. Adds significant value. **Pavé setting**: many small stones set close together to cover the entire surface. Difficult and labor-intensive. Premium pavé work commands premium pricing. **Invisible setting**: stones set without visible prongs. Notable for Trifari Philippe-era pieces. Particularly valuable. **Plique-à-jour enameling**: translucent enamel that allows light through (like stained glass). Rare in costume jewelry. Very valuable. **Cloisonné enamel**: enamel in compartments formed by wire. Used in some higher-end Asian-style pieces. **Links and chain quality**: high-end pieces have uniform, well-made links. Cheap pieces have inconsistent or poorly-soldered chains. **Clasp quality**: Trifari, Coro, and other top makers had distinctive high-quality clasps. Poor clasp quality is a warning sign of cheaper pieces or reproductions. **Condition factors**: **1. Missing stones**: single missing stones significantly reduce value. Pieces with multiple missing stones are often unsalvageable for collectors. Repair can restore some value but reduces originality. **2. Plating wear**: base metal showing through the plating layer. Light wear is acceptable; severe wear significantly reduces value. **3. Discoloration**: oxidation of base metal, particularly pot metal pieces developing 'pot metal cancer' (bubbling, cracking). Cannot be reversed. **4. Broken/bent mechanisms**: pin stems broken or bent, clasps non-functional. Can be repaired but reduces value. **5. Missing components**: pieces of a set (matching earrings, necklace, brooch) missing reduce overall set value. **6. Re-plating or restoration**: visible repairs or re-plating can reduce value compared to original condition, even if appearance is improved. **Condition grading** (standard used by dealers): - **Mint/New Old Stock**: perfect, often with original box/tags - **Excellent**: virtually no wear, all original parts intact - **Very Good**: light wear, original parts, fully functional - **Good**: visible wear, minor missing stones, functional - **Fair**: significant wear or damage - **Poor**: heavy damage, restoration needed Valued assesses materials and condition from photos, identifies construction techniques, and provides detailed condition grading with corresponding value adjustments.

Current Market Values and How to Sell

The vintage costume jewelry market has been active and generally appreciating for the past 15-20 years. Certain categories have seen strong gains while others have remained stable. **Current market value ranges by category**: **Signature designer pieces (top tier, appreciating)**: - **Schiaparelli**: $500-$10,000+ - **Miriam Haskell (signed)**: $300-$5,000+ for typical pieces, $5,000-$25,000+ for rare - **Trifari Philippe era (Jelly Bellies, invisible-set)**: $500-$10,000+ - **Schreiner/Warner/Robert Originals**: $300-$3,000 - **Weiss rare (Christmas trees, unusual stones)**: $150-$1,500 **Mid-tier makers (solid, stable)**: - **Crown Trifari**: $75-$500 typical, $500-$2,000+ for premium pieces - **Coro (basic)**: $30-$150 - **Corocraft / Vendôme**: $100-$800 - **Eisenberg Original sterling**: $150-$800 - **Albert Weiss**: $50-$250 typical, $300-$800 rare - **Hobé, Boucher, Mazer**: $100-$500 - **Matisse/Renoir (enamel on copper)**: $75-$300 **Entry-level vintage (affordable)**: - **Sarah Coventry**: $15-$50 - **Napier**: $25-$100 - **Monet**: $20-$75 - **Whiting & Davis mesh**: $50-$150 - **Unmarked but quality pieces**: $25-$200 depending on appeal **Specialty categories (collector sub-markets)**: - **Christmas tree brooches**: $50-$800+ depending on maker and era. Weiss and Eisenberg Christmas trees have strongest markets. - **Bakelite jewelry (1920s-1940s plastic)**: $100-$2,000+ for bracelets, more for figurals. Authenticity testing required (Simichrome polish or hot water + Formula 409 tests). - **Jelly Belly animal pins** (Lucite bellies): $300-$5,000+ for Trifari and similar. - **Regency-style floral enamel**: $100-$500. - **Deco compacts with matching jewelry**: growing collector interest, $200-$1,500 for sets. **Where to sell**: **1. eBay**: - Broadest buyer pool - Best for mid-range pieces ($50-$500) - High-end items often undersell here (not enough serious collectors) - Sold listings provide real-time market data - Watch for: photography quality matters enormously; multiple high-resolution photos including marks **2. Ruby Lane**: - Specialty antique marketplace - Higher average sale prices than eBay - Lower volume but more serious collectors - Better for high-end pieces ($200+) - Listing fees **3. Specialty auctions**: - For top-tier pieces (Schiaparelli, rare Haskell, Philippe Trifari, Jelly Bellies) - Doyle, Freeman's, Heritage, Rago for costume jewelry auctions - Commission 15-25% - Reach serious international collectors - Best prices for verified high-end authentic pieces **4. Specialty dealers**: - Contact costume jewelry dealers directly - They buy at 40-60% of retail to maintain their margins - Fast and easy but below-market prices - Good for disposing of mid-range collections quickly **5. Estate sales / garage sales**: - Lowest prices - Good for mass disposition of large quantities - Not worth it for individual high-value pieces **6. Etsy**: - Younger buyer demographic - Strong for stylable mid-century pieces - Less useful for high-end collector pieces **Photography tips for selling online**: 1. **Natural light**: outdoor or near a window. Overhead lighting washes out detail. 2. **Plain background**: white or neutral solid color. 3. **Multiple angles**: front, back, marks close-up, clasp close-up, any damage. 4. **Size reference**: include a ruler or known object for scale. 5. **Clear mark photos**: zoom in on maker marks. Buyers want to verify. 6. **Honest condition photos**: show wear, missing stones, any issues. Hiding problems creates returns and negative feedback. **Common selling mistakes**: **1. Cleaning aggressively before selling**: can damage pieces or reduce patina. Light cleaning with soft cloth is fine; chemical dips can destroy plating. **2. Misidentifying makers**: claiming a piece is Haskell when it's not, or describing a Trifari as 'rare' when it's common. Buyers verify, and misidentification ruins your reputation as a seller. **3. Overpricing unmarked pieces**: unmarked jewelry (even if well-made) sells for less than signed pieces. Don't assume your grandmother's 'beautiful brooch' is from a famous maker just because it's beautiful. **4. Selling pieces of sets separately**: necklace + earrings + brooch sets are worth more together than separately. Research whether your piece is part of a set before selling. **5. Underpricing high-quality signed pieces**: research comparable sold prices before listing. Many sellers undersell Haskell, Schiaparelli, and Trifari pieces because they don't realize what they have. **Building a reference library**: For serious collectors, invest in reference books: - **'Costume Jewelry: Identification and Price Guide' by Harrice Simons Miller** - **'Collecting Costume Jewelry 101, 202, 303' by Julia C. Carroll** - **'Warman's Jewelry: Identification and Price Guide' by Christie Romero** - **'Miriam Haskell' by Lucille Tempesta and Cathy Gordon** These books provide detailed photos, mark identification, and value ranges. For anyone selling seriously or building a collection, the ~$25-$50 investment pays for itself quickly. Valued provides real-time market data and identifies whether a piece is part of a set worth more together, so you can maximize value when selling.
