Sterling Silver Rings, Sateur, SUN, Seta, UNK, all Size 6.75, Clear Gems.

Gems are likely synthetic diamonds, Cubic Zirconia, or similar. Sateur is not marked outside the brand name, but their website indicates it's likely 925 silver with a thick white gold or platinum plate.

Not pictured, a 5th ring, same size and style,  but unmarked and seems to be some kind of Silver-tone plating over copper. Looks nice, very pretty, but is fashion or costume jewelry so I'm throwing it in so I don't have to mess around trying to sell it separately.
