Pearls are a very eco-friendly choice, because the water in which they grow must be clean and healthy in order to grow beautiful, healthy pearls. The conditions that form pearls are very delicate and involve a myriad of factors such as the temperature of water, pristine unpolluted waters, a natural parasitic intruder or surgically implanted mantle tissue, the density of mollusks, and the quality of the pearl’s environment among others. Our trusted pearl suppliers fight for clean water, and your purchase helps support sustainable farms and environmental advocacy around the world.
