PTM Pearl (Moti) 9.25 Ratti or 8.50 Ct Gemstone Men & Women bis Hallmark 925 Sterling Silver Stone Pendant

Pearl is an organic gem, because it comes from a living marine creature. Pearls form in oysters and other mollusks. The mollusks form the pearl around an object that enters their bodies. Cultured pearls grow in mollusks raised by humans who help them to form pearls. Natural pearls form without any human help. Both are beautiful and valuable, and come in white and other colors.
