Hi Randall, Give Matthew Ribarich a try (MRstones4U@aol.com),
714-645-9017, Box 10104, Costa Mesa, CA 92627.
I can't find his catalog right now, but as I remember he had a very
good assortment of sizes & shapes. He's good to do business with. He
handles marcasites, jade, rose cut garnets & rhinestones.
