Another great resource, if you are in NYC, and it also happens to be right by Metalliferous, is Dikra Gems. They have an amazing selection of almost any stone that you might want and can also work with you to provide specific cuts and sizes of whatever stone you might need.
Also they recently opened their online shop, if you don’t happen to be in NYC. You can’t actually buy anything online, but you can browse their selection and then hit the inquiry button to inquire about sizes, prices etc.
Or you can visit them in Tuscon 2010 in Feb.:
GJX – 198 S Granada Ave., Tuscon AZ. 85701, Booth 1508 Main Hall.
Wed. Feb. 3 – Mon Feb 8, 2010
Their NYC address is:
56 West 45th Street, New York, NY 10036
