Diamond Necklace

My ex bought me this necklace right before he cheated on me. It is sooo pretty but I want to get rid of it for obvious reasons. It has three small diamonds that move around on one side of the heart. The chain and the heart sterling silver and still very shiny/almost no scratches. I wore it for about a month and it’s been sitting on my dresser since. It’s so pretty, but someone else should get the opportunity to be happy because of it :) bought from Kay Jewelers. Chain is probably 16-18 inches
