Such a pretty ring. The ring is not hallmarked, but tested for 10K gold. There are 3 small cultured pearls--2 have a light golden color, and one is a pale lavender color. They measure approx. 3mm each. There are 22 Euro. cut Diamonds. Ring size is 5, weight is 3.0 grams. Condition is excellent. I would date this fine ring at c 1930's-50's.
