Stone Sourcing & Sustainability

Sun shining through the forest


Stone Sourcing

Our emeralds are natural, AAA quality, and not heat treated. They mainly originate from either Zambia or Columbia, then they are cut in Thailand, and then manufactured and set in California.

Our rubies originate mostly from Mozambique and sometimes other parts of Africa like Madagascar. They are cut in Thailand and are heat treated (It is Borax, no lead).

All of our sapphires are natural from this beautiful earth and are not treated or heated. 


Diamond Sourcing & Ethically Sourced Diamond

Our diamonds are ethically sourced. Suzanne Kalan works with the Kimberly Process; the diamonds are purchased from legitimate sources not involved in funding conflict and compliance with United Nations Resolutions. We guarantee that these diamonds are conflict free, based on personal knowledge and/or written guarantees provided by the supplier of these diamonds. 

Regarding acquired prior to January 1, 2003 Suzanne Kalan guarantees we have no personal knowledge to believe that these diamonds are conflict diamonds which have been traded in violations of any United Nations Resolution.


GIA Certificate Questions & Diamond Quality

For our diamonds, we use G color, VS quality diamonds and above.

If you would like a GIA Certificate, they charge $300+ to certify each stone. For this reason, the stones we use in our collections are not GIA certified. The only stones that are certified are the larger diamonds or emeralds that we use in some of our One of a Kind pieces. 

The diamonds we use in our Collections are G Color/VS or better in color and clarity. We buy the stones based on the quality, color, and grade in parcels and have been using the same suppliers for decades. Additionally, our product is sold in some of the world's top retailers. They all do their own checks once they receive the merchandise.

We are happy to offer a certificate of authenticity with your purchase stating the quality of the diamonds we use in each piece. Unfortunately, there is no "proof" we can provide for you regarding the quality of the diamonds. In fact, most of our pieces use diamonds that are higher in grade, color, and quality than G, VS but we say G, VS to be safe. We have been in business for over 32 years and are sold in the best stores all over the world. This is not something that can be achieved by being dishonest. We are a family run company who values honesty, especially when it comes to the specifications we provide our customers of our pieces.
