I put these two items together, I did not have a plain chain so I put this 18K gold chain with this heart. It is a beautiful chain, it has a slight rose gold tint. The heart is `10K and has 1/4C of diamonds . It is slightly over 3/4 with the bale up and down and side to side it is 1/2 inch. You can buy the chain or the diamond heart separately. One or both for you from Kansas.
