Vintage Sterling Silver Purple Quartz & Purple CZ Earrings

These are vintage sterling silver earrings set with purple quartz & purple CZ Identification Details Hallmarks: The back of the earring shows a clear "925" stamp, confirming they are made of sterling silver (92.5% pure silver). Below this is a maker's mark that appears to be "NV" or similar, which is common on vintage pieces. Gemstones: The earrings feature a double-stone design with a larger rectangular or "radiant-cut" bottom stone and a smaller square or rectangular top stone. Given the color and common pairings for sterling silver, these are likely purple quartz & purple cubic zirconia. Style: They are stud post earrings with a modern yet vintage aesthetic.
