10K Gold Ruby Coca-Cola Retirement Ring

Item Description:

This is a Coca-Cola employee service award ring, custom-made by Jostens, a renowned American jewelry manufacturer known for class rings and corporate awards. It features:

• A 10K solid gold setting
• A synthetic ruby (likely lab-created) gemstone
• The classic Coca-Cola script logo in relief on a blackened field
• Flat signet-style shape with beveled edges
• Inside engraving (likely Jostens hallmark and possibly gold purity stamp)
• Approximate size: Unverified, appears to be around size 10

Historical Background:

Coca-Cola has a long tradition of awarding milestone jewelry—rings, pins, and watches—for employee service, especially at the 10, 20, 25, and 30-year marks. These rings were:

• Not sold to the public, making them rare
• Individually customized, especially during the mid-to-late 20th century
• Often produced by Jostens or Balfour, two premium American jewelry firms

This style, with ruby and bold geometric shaping, appears consistent with 1970s–1990s production, though exact dating would require Jostens serial records.

Materials & Craftsmanship:

• Gold Content: 10 karat gold (~41.7% pure), durable and widely used for commemorative jewelry
• Gemstone: The ruby is likely lab-created, common for corporate jewelry, but retains value for design
• Condition: Good, with mild wear and tarnish consistent with age. The black background around the Coca-Cola logo has wear, but the engraving remains sharp.

Recommendation:

• If selling: Consider listing on collector platforms like eBay, LiveAuctioneers, or specialty Coca-Cola collector sites. Include “Coca-Cola 10K gold 20-year Jostens ring” in your title.
• If insuring: Insure at full replacement value — $600–$700 suggested for insurance purposes.
• If unsure of stone type or gold weight: A local jeweler can confirm if ruby is synthetic or natural and weigh the gold precisely to narrow valuation.
