Beautiful .50 carat total weight diamond stud earrings in martini white gold setting with screw backs. Each stud is .25 carat. I do not know the exact specifications, however no flaws or inclusions are visible to the naked eye. I recently went up a size, and no longer wear these. They are very high quality diamonds. Brand knew they were around $2000. I ship same or next business day! Smoke free home. All questions answered promptly
