I am trying to learn a little more about uncut diamonds. Are all uncut diamonds cuttable? How can you tell what can and cannot be cut? When a diamond is cut, how much does it lose in the process (Say you have a 2 carat uncut diamond and had it cut... about how many carats would be left when you were done?) How muxh does it cost to have a diamond cut? Or if anyone could refer me to a something I can get this information from that would be great! Thanks!
