Coro Jewelry Marks

Coro jewelry, renowned for its high-quality costume pieces, has graced the necks, wrists, and ears of fashionistas for decades. Identifying authentic Coro pieces often hinges on understanding their distinct markings. This comprehensive guide delves into the fascinating world of Coro jewelry marks, equipping collectors with the knowledge to accurately date and authenticate their treasures.

What are Coro Jewelry Marks?

Coro jewelry marks are stamps, engravings, or labels applied to pieces during production. These marks serve several purposes:

  • Identification: They establish the piece as a genuine Coro creation.
  • Dating: Specific marks often correspond to particular production periods, aiding in dating the piece.
  • Quality Indication: Certain marks denote higher-quality pieces within the Coro line.

Understanding Coro Jewelry Mark Variations

Coro employed a diverse range of marks throughout its history, spanning from the early 20th century to the late 1970s. Here’s an exploration of the most common types:

  • The “Coro” Mark: This is the most recognizable and frequently used mark, appearing in various forms, including script, block lettering, and with or without a registered trademark symbol (®).
  • “CoroCraft” Mark: Introduced in 1937, this mark signified pieces of higher quality and craftsmanship within the Coro line. Later versions combined “Coro” and “Craft” into one word, “Corocraft.”
  • “Vendome” Mark: Used primarily for Coro pieces sold through high-end department stores like Neiman Marcus, this mark denoted a specific marketing strategy rather than inherent differences in quality.
  • Date Marks: While less frequent, some Coro pieces feature date marks, typically in the form of two-digit numbers indicating the year of production.
  • Designer Marks: Certain pieces designed by specific individuals, like Adolph Katz, might bear their signature alongside the Coro mark.
  • “Made in Canada” Mark: Coro operated a Canadian factory, and pieces produced there were marked accordingly.

Dating Coro Jewelry by Marks

While not foolproof, identifying the mark on a Coro piece can provide valuable clues for dating:

  • Pre-1920s: Early Coro pieces often lack any markings or might have a simple “CR” mark, representing the founders’ initials.
  • 1920s-1930s: The simple “Coro” script mark and variations were prevalent during this era.
  • 1940s-1950s: The “CoroCraft” mark emerged in the late 1930s and became widespread in the following decades.
  • 1960s-1970s: The “Coro” mark continued to be used, with some variations incorporating a registered trademark symbol.

Additional Considerations for Authentication

Beyond relying solely on marks, consider these factors when authenticating Coro jewelry:

  • Material and Construction: Coro pieces are known for their quality materials, including enameling, glass stones, and plated metals. Flimsy or poorly-constructed pieces might be reproductions.
  • Design and Style: Research typical Coro design elements from the suspected era, such as floral motifs, geometric patterns, and whimsical themes.
  • Comparison with Known Authentic Pieces: Comparing the piece in question to high-resolution images of verified Coro jewelry can aid in identifying details consistent with genuine pieces.

Remember: While marks offer valuable insights, they should not be the sole basis for authentication. Consulting reputable vintage jewelry experts or appraisers is highly recommended for definitive confirmation.

By understanding Coro jewelry marks and their nuances, collectors gain the power to navigate the exciting world of vintage fashion treasures. Happy collecting!
