This is an authentic LeVian 14k tanzanite and diamond ring. Purchased from Macy’s LeVian trunk show. I’m not sure the exact size but I am a 5.5 and can wear on my ring finger. It’s 14k, 1 carrot of diamonds on the sides, and 1.2 carot tanzanite center stone. I paid 3,000 at a Macy’s fine jewelry trunk show. I do not have the original box but I can include a David Yurman box and pouch.
