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

January 27, 2016

It's the end of January moving into early February and that means it's time for the Tucson shows.  We are in the process of preparing our inventory for the start of our show at GJX.  For those of you who don't remember where we are or if you have not visited us in the past, our booth number is #1436 and we are open from 10:00 a.m. to 6:00 p.m from Tuesday, February 2- Sunday, February 7.  Sunday's show hours are a little shorter as we close down at 4:00 p.m.  We certainly hope to seeing many of you there!

Every year, just before our show opens, the four Coasters gather to ready the inventory to offer the best prices possible.  These new prices will be reflected on our website starting today.  A few prices may increase but many will go down so keep a watch on the new items list as that is where the price changes will be seen.

We are constantly upgrading our website to make it easier to navigate, reserve, and purchase stones.  Larger pictures of most of the inventory have been added and can be viewed by clicking on the thumbnail photos.  By registering and logging in, you can track current and past orders, change your password, etc.  Our secure website makes it easy to pay for your order by credit card (Visa, MasterCard, Discover and now we are also accepting American Express).
