EARTH CONSCIOUS

At ALTR, maintaining a low carbon footprint is essential. Good stewardship of the earth isn’t just smart policy, it’s inseparable from ALTR's DNA. Mindful of the preciousness of all non-renewable resources, ALTR uses cutting edge technology requiring less than a liter of water to produce a 1-carat diamond. ALTR’s exclusive use of US certified recycled gold is a further reflection of their commitment to conscious and responsible stewardship of the earth. Inspired by Ahimsa, the embodiment of respect for all living things, ALTR is beauty without cruelty.
