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 three 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.

From all of us at Coast to Coast, we want to thank all of you for your continued patronage and business with us through the years.  The Tucson show was very successful for us again last month.  It was great to see many of you in person as it is every year.  It was also wonderful to meet several new faces from around the world that share our interest and passion for rare stones.

As happens every year at the conclusion of the Tucson shows, the Coasters have taken a bit of time off after the big dance in the desert to recharge our batteries for the coming year.  We are now back at the wheel, cutting for this year's inventory.  We will continue to make regular additions to the website as stones are cut and ready for sale.  Initially, you will see these gems on the "New Items" list where they remain for 30 days.  If you are looking for something in particular that you don't see on the website, please do email to let us know.  We will do our best to acquire for you through our network of national and international contacts.

For the last three years, John has been writing an article on a different rare stone for each edition of Gem World International's publication, the Gem Guide. There have been articles on danburite, rhodochrosite, sphene, hauyne, sphalerite, vesuvianite, tugtupite, benitoite, fluorite, apatite, and prehnite. Relevant gemological data as well as locality information, availability, care and handling can be read in these articles. The Guide is a fantastic resource for pricing, appraising, and market conditions. If you don't already subscribe, we would highly recommend it.

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).
