I cannot help you. Mama Minerals could help, also UNM might help too, contact Rio Grande Jewelry Supply, they may know a person who could help or narrow your search.
We will do our best, but we do not buy cut gems, so it is not our area of expertise. The ones we have for sale are on note. The best place to find out about cut gemstones, the type you'd set into fine sterling or gold, is Southwestern Minerals on Central just west of Louisiana. They have the best selection of precious and semi precious cut stone in the state.
General information here... When you ask a question on gere you are asking people that have visited not people that work there. You may want to call them. Im not sure if they do or not
Call them
There is a good chance that they will be able to help you
