RTL is a direct diamond importer and exporter. We buy our diamonds and gems direct from the source, in the rough or polished, which enables us to offer substantial cost savings to you. RTL maintains a substantial inventory of loose diamonds, which, combined with our worldwide contacts, guarantees we can provide you with a one-in-a-million diamond for your once-in-a-lifetime purchase.

Please call us at (415) 713-6697 or e-mail us, with your specific criteria or to set up a personal meeting. Our offices are conveniently located in the Shreve Building at Union Square in downtown San Francisco.

Check out the ABOUT RTL page for more information about the company and our estate jewelry buying division.






RTL offers custom design services for one-of-a-kind pieces, as well as access to pieces from most of the top designers. We encourage you to take your time in finding the right setting. With the purchase of any loose diamond of one carat or above we offer, at no additional cost, a four or six-prong, 14K white or yellow gold, solitaire setting.
