Thats really cool! From my past of reading up on stones, the different colors come from different chemicals included in the diamond... so the yellow might have one element added, while the blue wuld have another. I forget wqhich they are, smething like zinc being present in one, not in another to create the different colors.

I would love to have this done for the kids -- but not at those prices. Their Nan passed away a few years ago and have nothing to remember her but hteir own memories. She was so vital and important in their lives.... and we have not figured out what to do with her ashes. We just knew it had to be as special as she was. Darnnit, I wish we weren't poor and struggling right now.
