14k white gold pendant with 5.81mm diamond

*14k, white gold pendant *5.81mm (approx. .75ct.) round diamond *weight of diamond undetermined, as jeweler said they'd need to disassemble, and I dont want to do that. *chain hole is quite small, so a smaller diameter chain would be needed (chain NOT included) *beautiful and VERY Sparkly *very clear color, no shades of yellow that I can tell *no specifics on diamond, but with magnetizing, I can see a couple teeny black inclusions. I've tried to show pictures with red lines indicating.
