Each custom ring is a work of art made to fit your unique tastes and personality. With Bez Ambar, high quality does not mean astronomical cost. Every stone comes directly from the mine to Bez Ambar's expert hands. Each setting is designed and manufactured in our Los Angeles location.


As a master diamond cutter, the inventor of the Princess cut, Bez Ambar, is able to provide you with the most incredible and perfect diamonds on the market. With Bez Ambar handpicking, cutting, and polishing each incredible stone, specially selected from his network of gemstone mines and manufacturers, you can be sure that you are receiving only the best, ethically sourced, and conflict free diamonds.



All Bez Ambar pieces are crafted with outstanding care and focus by our master artisans, meeting rigorous quality control standards and favoring quality over mass production. Bez Ambar’s success over the last three decades has proven the dependability and primacy of the Bez Ambar brand.

Recently there has been a rise in incidents where non-authorized Bez Ambar jewelry stores are attracting customers with our designs and images, only to offer and reproduce a counterfeit.

Many of those customers contact us later displeased with the workmanship and overall quality of their newly purchased ring in hopes that we can repair it and bring it to match the original design. Unfortunately, the replicated items cannot be fixed and must be remade correctly. At Bez Ambar, we use state of the art equipment and various unique methods not available to other jewelers.

We guarantee that by purchasing a genuine Bez Ambar design, you will receive nothing short of what you have seen in the beautiful images displayed on our website. The craftsmanship and quality of work are of the highest standards and will prevent future disappointments and frustrations that may accompany any replicated designs. There is no reason to settle for anything less than the original!
