Rarestone International

Welcome to the Coast to Coast Rare Stones International website.

Coast to Coast Rare Stones is a cooperative of three full-time professional lapidaries with more than 130 years of combined gem cutting experience. 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.

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.

Happy Spring! We wanted to send out a very big thank you for your continued business. It was so good to see many of you at the shows in Tucson and look forward to seeing you somewhere along the line this year. Your business is important to us and we appreciate your continuing relationship with us. As always, we look forward to helping with any of your colored stone needs. Please let us know your specific requests and we will do the best to source for you when possible. Stones are added to the website weekly.

We would like to remind everybody that we are available by Virtual Zoom meetings should you need to see an expensive item up close before commiting to purchase. We continue to offer our 10 day approval period on our entire inventory. I hope that our "Virtual" contact does not go away completely but it will never replace the person to person meetings that we have with all of you each and every year. We certainly look forward to seeing you in person this year at sometime, somewhere on the Ball.

Welcome to our upgraded Coast to Coast website! We have the same great content with a new look and new features.
*Within the inventory listings, the view for each species now shows thumbnail displays with a larger photo than our old website. Clicking on a thumbnail will give expanded information and clicking on the photo again will isolate the picture.

*We have added a “Gemstone Info” link under the Glossary tab that will give gemological and other pertinent data on the gems that we supply. This list will be added to over time. If you have a particular gem that you would like to have listed, feel free to contact us.

*Please sign up for our Newsletter (three or four per year) below to keep up with us!

*The website is now also mobile friendly on your tablets and phones.

By registering on the website through the Login Page (icon to the right of “Contact Us” in the header) and then logging in, you can track current or past orders, change your password, etc.

All of us at Coast to Coast would like to thank you for visiting our upgraded site and appreciate your business.
