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!)!
