I loved this ring so much I got one for me! It is a gorgeous 10x8 mm (2.9 ct) emerald cut, genuine ametrine ring! An ametrine is a genuine amethyst and citrine that have been fused together to form a stone that is half purple and half yellow. BEAUTIFUL! In addition to the ametrine, there is .12 ctw of round, genuine diamonds. The setting is solid 10k yellow gold with an open works, filigree band. The ring weighs 3.5 grams and is available in size 7 or 8. It is slightly sizable by your local jeweler.
