My co-worker was complaining that he wanted to get his wife jewelry for Valentine's Day, but that his taste didn't match hers. He likes dark, dramatic jewelry but she likes daintier, more mainstream designs. I suggested a compromise of this gunmetal necklace by Micky Lynn. The dark chain, uncut stone, and raw setting give it an edge. The simple chain and circle pendant make it wearable for everyday occasions. It's $117 on Amazon.
