SUSTAINABLE MATERIALS
Rest assured knowing that all Ecksand diamonds are ethically sourced. Natural and lab-grown diamonds above 0.50 carat are GIA- and IGI-certified respectively. Diamonds below 0.50 carat are either Ecksand-certified in compliance with the GIA grading standards, or they come with a GIA or IGI certificate (depending on the type of diamond selected).
No different than our diamonds, our curated selection of natural gemstones and pearls are ethically sourced, so their colour may vary slightly from one Ecksand piece to another.
Created for lifetime wear in our green atelier, all of our jewelry pieces are crafted with 100% recycled gold or sustainable platinum.
