I’m guessing that this is sapphire and not tanzanite or another blue hued stone. Whatever it is, I love the innovative band. Sapphire is my birth stone and I have always (fortunately!) loved it.

Steve is my jeweler and he’s amazing! He reset my engagement ring with loose diamonds that I had from a brooch my grandmother gave me and I get compliments every day!
