One carat loose perfectly cut square diamond, ranges from 1.00 to 1.07 carats, this special value is graded at least J color, VS-1 clarity. J color can be a great niche because they look great in Passion Fire cutting, can be set in white metals, but not very many people are looking to buy these. You probably wouldn't be looking either if we hadn't told you, so be open minded on these and you will be very pleased.. Each has been personally inspected by David Nygaard, and comes with a Passion Fire grading report. Only one diamond in 100,000 is good enough to be a Passion Fire!
