Pearl vs Moonstone: Origin
Pearls
Pearls, also known as moti stones, are organic gemstones that form inside certain mollusk species, such as oysters and mussels. They are formed when an irritant, such as a grain of sand or a parasite, enters the mollusk’s shell.
The mollusk coats the irritant with layers of nacre (also known as mother-of-pearl) to protect itself. Over time, these layers build up to form a pearl. Pearls can occur naturally in the wild or be cultured on pearl farms.
Moonstones:
Moonstones are mineral gemstones, specifically a variety of the feldspar group of minerals. They are formed through a process of solidification and crystallization of molten rock (magma) or through metamorphic processes in the Earth’s crust.
Moonstones are primarily composed of potassium aluminum silicate with sodium and calcium feldspar. They are inorganic minerals formed through geological processes, unlike the organic formation of pearls. Moonstones are found in various locations around the world, including Sri Lanka, India, Australia, and parts of the United States.
