Allegations Against Effy Jewelry

Effy Jewelry came under attack when a gemologist contracted by Macy’s (one of Effy Jewelry’s partner retailers) noticed that the stones being sold under the Effy Jewelry brand were sub-par (the article is available here).

The initial focus was on Effy Jewelry’s rubies. Rubies are the second hardest stone, only slightly less so than diamonds, and have become increasingly rare since Burmese mines were shut down in the early 2000s. Gem dealers found an alternative source of rubies in Africa, but the stones were of lesser quality than Burmese rubies, filled with fissures.

Effy Jewelry is accused of adding leaded glass to the poor quality stones, then treating them with heat to enhance their color and presentation. The Jeweler’s Association states that these rubies are not “real” as they fall short of the durability offered by a genuine stone.

Even more disturbing, when these artificially enhanced stones, called “treated rubies” “enhanced rubies,” “composite rubies,” or “hybrid gemstones,” are heated, the filling may leak out, causing the composited shards of inferior ruby to shatter.

To the naked eye of an ordinary consumer, there is no visible difference. However, fine jewelry is often considered an investment that will last many generations while holding its value — a promise these composited and treated stones can’t uphold.
