This is a fine Tsavorite and Diamond ring. The Tsavorite is a clear medium green color. Not included like Emeralds, this stone is clean and beautiful. Oval in shape, the stone measures approx. 6mm X 8mm. I am not a gemologist so I don't know ct. weight. The band is hallmarked 14K yellow gold. The metal surrounding the stones is white gold. There are 2 fancy baguette Diamonds, one on each shoulder. The ring is size 5. Could be easily re-sized. This would make a lovely engagement ring for the lady who loves green. Weight is 1.5 grams. Condition is excellent. I would date this lovely ring at c1970's.
