|I think these beauties are oxidized sterling (unmarked/judging only by the ear wires)|
I also found this super-dirty Italian Omega chain. It cleaned up and polished just beautifully! The ring on the left is faceted by actual tiny bends in the sheet silver which catch the light. The ring on the right looks to be sandblasted to cause the tiny sparkles.
|I think this is a glass cabochon in a deco setting---and its emerald cut is amazing!|
