A lovely and large black diamond solitaire set in sterling silver in a durable 8 prong setting, size 7. This diamond is an oval 11x9mm stone. This diamond is enhanced and heat treated from carbonado diamonds to make the color more uniform. Comes with a GIL certificate. The certificate states that it is a 10x8mm stone, but I could only set it in an 11x9 setting, it is larger than listed on the certificate. Can be easily removed from this setting and put in your own at a local jeweler. Also comes with a nice jewelry box. I'll send priority mail free of charge. Thanks for looking!
