Art Deco 1.25 Ct Oval Lab Alexandrite Floral Bridal Set

Recieved the rings and got them checked for authenticity. Turns out I paid for the setting (which was the correct metal), but the stone was something attuned to purple glass (fake amethyst) instead of alexandrite like I ordered. I thought about maybe keeping them and getting a different gem, but the setting sits very high and the rings themselves are very thin. I will be returning the rings.
