This gorgeous trillion diamond was set on a clunky white gold chain when I found it. I have substituted an elegant vintage 14k yellow gold bar chain and love the combination! The diamond is a drop-dead gorgeous and sharp-angled trillion, with a shallow cut that gives it a spread well over 1 carat. 

Set on an 18" chain, it is the perfect never-take-off accessory that elevates any outfit with a touch of edge.
