[meteorite-list] [MICRO] Diamonds and Ureilites

[Greg Hupe]

Hi Greg S. and List,

Greg S. asked:
"I was wondering if anyone knows which Ureilite contains the most diamonds, 
and how much (perhaps by percent) it contains. I've read that they are often 
difficult to cut because of the diamonds in the matrix."

Ureilites contain 'micro'-diamonds, and in a word on how difficult they are 
to cut and polish, "A Pain!" The first ureilites we purchased in Morocco 
several years ago we learned just how painful and expensive they were to 
prepare. Basically if you are using an 8" .012 diamond blade, expect to go 
through at least one blade per inch of cutting (if you are lucky!)!

Best regards,
Greg

Much Thanks,
