This necklace is very high quality; I love that it doesn’t shift around on the chain and it seems super sturdy. This exceeded my expectations! As a stem girlie, it is a dream gift!!

This is a fantastic gift for a chemist. The rose gold looks a tad more copper than rose-gold-colored, but otherwise, it’s exactly as described. I can’t wait to gift it.
