Welcome to the Coast to Coast Rare Stones International website. We specialize in those gems that you are less likely to encounter anywhere else, but we also carry the best quality commercial colored stones, combined with the best custom cutting you will find. In fact, we have the most varied selection of quality colored gemstones you will find anywhere, ranging from talc (hardness=1) to ruby and sapphire (hardness=9), with an occasional diamond thrown in to round it up to 10!

Coast to Coast Rare Stones is a cooperative of four full-time professional lapidaries with experience in gemcutting dating back to the early 1970's. We travel the globe in search of unique materials to interest collectors as well as cutting stones that are appropriate for setting into jewelry. We have been involved in the mining of colored gemstones including benitoite and spessartite garnet in California, tourmaline from Mt. Mica in Maine and Northwest Territories in Canada as well as a number of rarer species from all over North America. Our contacts within the gemstone mining industry make it possible to bring you the finest quality gems at the best price.

All of those stones that are marked as "Cut By Us" are cut in our offices here in the United States and Canada. We tend to cut the best and biggest stones out of the parcels we buy, but we send out our smaller stones to factories that facet to our precise specifications. Be assured that you are getting the best quality cut stones that you can find.

Also, check out our "Clearance" pages for gems that came from old collections, or items of which we have too many. These are priced to sell quickly, so that we can get back to cutting our top quality gemstones.

We offer geological and gemological consulting with experience in gem site exploration and evaluation. Our backgrounds are listed in "Our People". We are continually cutting; if you have questions about any of the "inventory" or are looking for something in particular, please "contact us" with your request, email address and phone number. We update our site daily, so please check us often.

"'Underrated' iolite on a slow rise" National Jeweler, August 25, 2015

It is with great sadness that we report the death of Art Grant, one of the founding partners of Coast to Coast, on September 24, 2015.  Art, along with Mike Gray and John Bradshaw formed the company back in 1987 to consolidate their rare stones and do business under one roof.  Art was a hard guy to slow down, particularly at a trade show as he scurried from dealer to dealer to acquire rough to cut the next great rare stone.  Fluorite was one of his favorites, and he was proud to have cut what still remains as the world's largest faceted fluorite at 3965 ct.  It was purchased by a private collector and later donated to the Smithsonian in Washington D.C. where it remains on display.  It was Art's idea a little more than twenty years ago to expand our group of rag tag cutters and include Brad Wilson of Kingston, Ontario into the company.  Although Art stepped back from cutting more than 10 years ago, he still kept a finger wet at the wheel from time to time, and of course brought his daughter, Nancy Pritchard into the company to help with the gemstone cutting as well as the day-to-day business and trade shows.  Art will certainly be missed by not only his fellow partners in Coast to Coast, but also by the hundreds of friends, students and acquaintances that he made over his 90 long years.  Rest in peace.

We have been fortunate to have been cutting almost all of the daylight fluorescent opal from Zacatecas, Mexico that has been being mined over the last few years. Check out the article in the latest "The Journal of Gemmology" Vol. 34, No. 6, co-authored by one of our cutters (MG), with cut stones both on the cover, as well as in the article. Watch for stones being listed on this site in the coming months!
