With roots that stretch back to 1933, ALTR is a third generation family-owned business that continues India's great jewelry-making heritage. Royalty is in our DNA.  Having crafted heirloom jewels for the kings and queens of India, ALTR has a regal lineage. As the first atelier in the world to make lab grown jewelry, we are also disruptors. While our diamonds refract light in stunning and mesmerizing ways, there is nothing mysterious about their origins.

Every ALTR created diamond is certified, so you can have perfect peace of mind. ALTR's exclusive use of recycled gold reflects our commitment to conscious and responsible stewardship of the earth. We have a heritage of craftsmanship, and we honor the traditions of Indian artisans while innovating new ways to create the world’s most beautiful and purest diamonds.
