Every genuine Black Opal is different, making it one of the most unique center stone options for your class ring. Color variations may include: green, blue, yellow, red, and purple. Black Opals only come in a cabochon form, meaning they are polished and not facetted.

Given the softness of opal, 5.5 to 6.5 out of 10, it's not recommended for daily wear. However, Black Opal's rarity and combination of many colors makes every class ring we upgrade with it truly stand out from the crowd. We receive more and more requests for Black Opal upgrades every year.
