August 29th, 2010 No comments

Barbra over at Gemologyonline made a post recently that reminded me a an important article that I forgot to post about, so here it is, better late then never!

This spring, the New York laboratory examined a 17.02 ct reddish orange spinel that contained a few small expansion halos or “blebs” emanating from strings of minute inclusions. The appearance of the inclusions suggested the stone was of natural origin — but may have been heat treated.

GIA, NY Lab, IDs a CVD Diamond Over 1 Carat in Size

May 6th, 2010 No comments

This 1.05 ct pear shape (9.81 x 5.95 x 3.06 mm) was color-graded as equivalent to G. In addition to pinpoint inclusions, it contained some feathers and fractures along the girdle, and its clarity grade was equivalent to I1.

Well, this will make things a bit more difficult in determining whether a diamond is natural or synthetic. So, folks, pay some very close attention to your diamonds you get in to ID and/or appraise, this could be a very costly mistake! “If in doubt send it out!™”  I doubt these are saturating the market currently in large numbers, but it more then likely will not be long until they are!

I do need to add that technically my initial description of the image was actually not totally correct!!
