Stunning ring!
Gem Type: Ruby, Ring Size: 5
This ring looks so very expensive! It’s exactly what I wanted! The ruby stones are exquisite, and the gold band is delicate yet sturdy. The ring looks like a vintage piece of jewelry. It arrived earlier than I expected which was great! I highly recommend this lovely ring!
