Opal sits at 5.5 to 6.5 on the Mohs scale, so that means bezel or halo, not prongs, on rings. October birthstone energy deserves a protective setting, but in earrings and pendants the hardness question largely disappears.
Elemental Detail
10kt yellow gold meets the legal definition of karat gold in the U.S. and Canada. It is real gold by any standard that counts, not a plated or filled approximation.
Value & Quality
The qualities that make a piece of jewelry meaningful (its finish, construction, material integrity) don't always rely on a high price point. Ross-Simons has spent more than 70 years sourcing to that standard across its full range, resulting in a beautiful selection of styles at every level, for every occasion.
