Snappy casual with class

Nice design. Low profile black diamond adds jazz to the simplicity of the design. Nice and sporty-unique design! If you like the picture you will enjoy the product. Great companion ring to the gentlemen's version which I also purchased for my husband! Check it out!

Bought this ring for my lady.

Saw this on the website and thought it would be original since I've never seen a combo like this. Ordered the ring and had it engraved for no charge, was made to order, came in, and gave it to my lovley lady. She loves it and I'm a happy camper knowing she likes the simple yet elegant design I appreciated in this ring.
