Buying Guide to Vintage Coro Jewelry

If you are looking to add some vintage Coro jewelry to your collection, you have come to the right place. Here you will learn about the history, jewelry marks, materials used, most collectible pieces, and tips on how to buy.

Coro Jewelry is most noted for its collection from the 1930s to the 1950s featuring brooches, double-clip brooches, necklaces and bracelets. Its great success was due to the quality of their designs, the affordability of the pieces and the appeal to a wide range of consumers.

Coro is a great brand to start your vintage jewelry collection with because it was one of the largest costume jewelry producers of its time.

Brief History of Coro Jewelry

  • In 1903, Emanuel Cohn and Carl Rosenberger founded their eponymous accessories boutique on Broadway in New York City. At some point, they decided to focus on jewelry, even though neither one of them could, or wanted to, design jewelry. They hired Adolph Katz who, as Director of Design, selected talented designers and styles of jewelry that fit in with the owners’ vision. By the 1920s, the jewelry was sold in dime stores across the US.
  • In 1929, Cohn and Rosenberger opened a factory in Providence, Rhode Island, and soon became the largest manufacturer of costume jewelry in the country. Their jewelry was sold in retail stores across the US. The company not only survived the New York stock market crash of 1929, but it thrived. They opened a branch in England in 1933 which succeeded in spite of the Depression and widespread unemployment.
  • In 1937, the company began producing a higher-end line of jewelry signed Corocraft.
  • In 1943, the company was incorporated as “Coro, Inc.,” (for the first two letters in each man’s name).
  • In 1944, Coro started its Vendôme line (named after the city in France), the most expensive line.
  • Coro’s brilliant success lasted through the mid-1950s, when it sold the American assets to Richton International Corp. of New York. The company’s downfall began with the beaded jewelry of the 1960s and then, in the 1970s, the competition from the tailored costume jewelry for everyday and business wear (e.g., Monet) and the influx of costume jewelry from Japan, Hong Kong and Taiwan. The American branch of the company folded in 1979; the branch in Canada lasted through the 1990s.

Jewelry Designers

Gene Verecchio became head designer at age 22. During three decades at the company, he created many of the best-loved Coro pieces. He is most famous for the “Quivering Camellia Duette” line as well as jewelry made with faux moonstone multi-colored cabochons.

Francois was a designer from 1938 to 1960. His specialty was beautiful flower-shaped earrings and floral brooches in heavy gold-plated metal with a textured Florentine finish. He had his own line at Coro, “Francois,” that was high end in the same category as Corocraft and Vendome.

Oscar Frank Placco tended to concentrate on the mechanical structure of jewelry. One of his earliest designs was for an ornament clasp in 1934 that led to Coro’s Duette series of brooches.

Carol McDonald first designed a bracelet with an attachment for securing a flower. She is also credited with the clown designs of the 1940s. 

Lester Gaba was a well-known sculptor and artist who designed patriotic pins during World War II.

About Coro's Jewelry Collections

Coro had three jewelry lines: Coro, Corocraft, and Vendome. Coro offered the most affordable costume jewelry, Corocraft was in the middle, and Vendome was their high-end brand. 

Even though Vendome is a higher-priced collection, some of the most sought-after pieces by collectors today are the Coro pieces, namely the Duettes produced from the 1930s and 40s. 

Corocraft (or Coro Craft) is a step-up from the Coro line in quality, price, and prestige. The famous Jelly Belly pins were introduced under this line. Most vintage Coro pieces were built on metal frames, whereas Corocraft items were often made of sterling silver or plated in gold. Rhinestones were referred to as "Diadem Jewels".

Vendome was introduced in 1944 and replaced Corocraft in 1953. Vendome featured serious bling including rhinestone-drenched chokers, cabochon-adorned silver-plated bangles, and gold-plated pins designed by Vendome’s Helen Marion, who was inspired by the great Cubist artist Georges Braque. Vendome also utilized Lucite in new and exciting ways, with designers shaving and forming Lucite into organic shapes with unexpected colors. Vendome is known for their charm bracelets and faux pearl necklaces.  

Most Collectible Vintage Coro Jewelry

Coro launched their first Duettes in 1935. The Duettes are two dress pins (or brooches) locked together by a mechanism invented and patented by the Coro company. Women could wear one pin by itself or both together as a Duette. Sometimes these pins are signed simply “Duette.”

The famous “Quivering Camellia” duette is also a trembler pin (see below).

Some Duettes are simple geometric designs; others are whimsical flowers or birds. A pair of horse heads and a pair of enamel owls are particularly sought after.

Smaller, lightweight versions of Duettes were sold after WWII due to the switch to lighter synthetic fabrics.

Trembler Pins

Much of Coro's early success was due to the company's design director, Adolph Katz, who created Coro’s en tremblant floral pins. 

A trembler is a type of brooch on which a small part of the pin is set en tremblant (French for “on a spring”) so that it trembles or quivers when the wearer moves. Floral designs are most popular for tremblers or pins depicting birds or winged insects.

Jelly Belly Pins

Jelly Bellies were first made in the late 1930s after DuPont invented Lucite, a thermoplastic acrylic resin product.

The small pins often depicted animals, but also pieces of fruit, musical instruments, ballerinas, people, modes of transportation, etc., all with a clear Lucite center stone (like a jelly bean). 

Later, Coro used colored glass centers, also highly treasured by collectors.

Patriotic designs by Lester Gaba during WWII.

How to Identify Coro Jewelry

Know Your Jewelry Lines

Be sure you know the difference in Coro’s product lines. The Coro line was aimed at lower- and middle-income consumers and offered a broad range of motifs. Coro Craft was higher end due to more expensive materials. The top of the line was Vendome, which was made from the finest materials. 

Check the Hallmarks

Coro used a variety of marks on their jewelry and can be seen on the back of the piece. Refer to this handy guide to see all of Coro's jewelry marks. 

Use Reference Books

It’s common for fakes to be larger than the original piece because they’re made in larger molds. The book Coro Jewelry: A Collector’s Guide: Identification and Values gives a detailed guide to vintage jewelry collectors.

Be Sure of Quality

Fakes will be cruder, have poor quality settings and stones, as well as flashier, bright plating.

Tips on Purchasing Coro Jewelry Online

  • Obtain close-up photos of the back so you can look at the specific clasp (e.g., the Duette) and compare it to genuine Coro pieces.
  • Use photos to verify the signature.
  • Make sure you have accurate measurements of the piece.
  • Check the vendor’s reviews and feedback from customers.
  • Read the vendor’s "Shipping and Return Policies."
  • Use a safe method of payment, e.g., PayPal, in case of any disputes.

  1. I have a rather old brooch, possible before 1940, that I need information on and can not find another one like it anywhere. It is labeled Coro and looks like a star flower. The top right corner needs repair and I can repair it if I can find another one like it to go by. If you contact me I can send you pictures. I’m only looking for pictures of one to go by for repair.

  2. I have a Coro silver color pin that has glass or plastic or maybe bakelite flowers with different color stamens and some of the flowers have blushes of color or dots of color on the tips. Green carved leaves are there as well. The flowers and leaves are on wires. The stem is silvertone with silvertone leaves that have a barely perceptible design on them. The back also has a few silvertone leaves. It was extremely hard to see the Coro symbol, but I managed to do so. I found 0 info about this pretty pin online, but I believe it’s from the early 1900s. It’s marked Coro and looks antique. I’ve had this pin at least 30 years myself, having bought it at an estate sale. Thank you for any info you can give me.

  3. I have a vintage Coro Dumbo Disney pin from the 1940’s. I am looking for someone to clean it and perhaps do some paint touch up on it. Do you know of anyone that might do this?

    • Hi Joe, thanks for stopping in. I looked around on Etsy and did a quick google search, but I can’t find anyone that does the kind of restoration you are talking about. Maybe search on youtube for DIY vidoes and you could restore the piece yourself!

    • Hi Aug, thanks for your question. As far as I know, Coro did not produce jewelry with diamonds or platinum. Coro is a brand that focuses on affordable jewelry, so they used rhinestones, plated metals, and poured glass in their jewelry.

      Let me know if you have any other questions!

  4. Hi there …I have a Coro necklace that has lost two rhinestones. Is there such a thing as a Coro repair service? Or something similar?

  5. Did Coro make trembler pins that were not marked? I have a double trember pin of 2 maroon liles with green stem and leaves. The center stamins tremble and it has rhinestones throughout. It looks to be well made and in lovely condition. The only mark I find is a small flower-like outline that was very hard to find. Thanks for your help!

    • Hi Josephine, it is possible that some of Coro’s jewelry is unmarked – sometimes the mark wears off, sometimes not every piece in a set will not receive a mark. But in general, I don’t trust jewelry that is unmarked. Coro’s jewelry style was copied by other jewelry manufacturers. I would suggest looking through Coro’s jewelry patents and see if you can find your trembler pin. You can browse through a bunch of patents here:

      Thanks for stopping in! Let me know if you have any other questions 🙂

    • Sure Greta, as long as you aren’t directly copying and pasting (write the info in your own words please). And as long as you give me credit and a link to my site 🙂
