I am looking for a source of raw diamonds to set in pieces of
jewelry. I saw some at the Tucson show, but I haven't seen any
First be prepared for possible sticker shock. Then again, this was
meant to be cut (into high quality stones). These two places can
absolutely be trusted.
At the second you may also want to ask about lower grades, I2 maybe,
or less etc. (minimum order $350 for any order on anything). I am
sure there are other places as well, I think someone on the rough
for sale list (caution needed) once had some etc. Most (places) if
they ever get any it is only once in a blue moon. Except those only
available to those in the trade. Still you may wish to keep looking.
