CIBJO Rules on Pegasus Diamonds, Rhodium Plating
CIBJO tackled the disclosure of "Pegasus" enhanced diamonds and the definition of "white gold" during its annual
congress in Bern, Switzerland, last week.
The confederation of jewelry and gemstone industry representatives, which sets international guidelines for fair
trade practices in the jewelry industry, expressed concern about Lazare Kaplan International's decision to sell
diamonds enhanced with an undetectable process. LKI and its subsidiary Pegasus Overseas Ltd. recently agreed to laser
inscribe the diamonds' girdles to identify the process, which was invented by General Electric.
CIBJO representatives don't believe this is enough. "According to CIBJO international gemstone disclosure
guidelines, diamonds that have the 'Pegasus' type of color modification should be clearly designated as 'treated' in
verbal and written descriptions right up the supply chain and in dealings with the consumer," CIBJO says in a release.
"The presence of a lasered identifying mark on the girdle makes no difference to this."
The delegation also declared selling rhodium-plated yellow gold jewelry as "white gold" an unfair trade practice.
CIBJO says a more precise definition of color in metals will be arranged in upcoming months.
CIBJO further announced that its long-awaited revisions to its "Blue Book," its gem nomenclature and disclosure
guidelines, will soon be available, and will also be posted on its Web site (www.cibjo.org).
