Hello all,
I am looking for images of laser damaged diamonds. Barbra, back in 2007 you had images of a diamond damaged in this way, but I can't seem to open the images..
Anyone out there have any links or images for me?
Thanks for the help,
Richard.

Specifically, I have a diamond with a surface groove that is black and "furry" looking; looks like graphite. Won't boil out in acid. I fear we may have done it on our laser-welder, but I never saw the stone before we worked on it. Does not look like any knot or inclusion I have ever seen before. Sorry no images from this end.
thanks, R.
