Got the Alexandrite ring for my girlfriend as a promise ring. Absolutely beautiful - She loved it!
I originally bought this as a gift for my friend. It came in the mail today and I liked it so much that I just ordered one for myself (in white topaz, mine is alexandrite).
It is beautiful and I can not wait to give it to my daughter
