STERLING SILVER 6mm .84 CT ROUND CZ POST STUD EARRINGS

Vintage sterling silver shiny post stud earrings. 6mm diameter on the round CZ stone is equivalent to .84 carat weight. 3 prongs hold the CZs. The back of the basket is stamped 925, CZ, China, and SW. I don't know what the SW means, it may be a maker's mark. The earrings backs are also stamped 925. In excellent preowned condition.
