Pearl Identification

Pearls, the only gems created by a living organism, have fascinated humanity with their serene beauty and lustrous appeal for centuries. Formed within the soft tissue of a living shelled mollusk, pearls are truly a marvel of nature, embodying purity, elegance, and grace. Unlike other gemstones mined from the earth, pearls are harvested from the depths of the sea and freshwater bodies, making each pearl unique in its formation. Their value is determined by several factors, including size, shape, color, luster, and surface quality.

At STEMart, we specialize in the intricate process of pearl identification, employing sophisticated techniques to evaluate these precious gems. Our expertise ensures that clients receive detailed insights into their pearls' authenticity, type, and quality, enhancing their appreciation and understanding of these natural treasures.
