In the world of gemstones, pearls stand out as unique and captivating treasures from the sea. Whether you’re a jewelry enthusiast or simply looking to purchase a special piece, understanding the different types of pearls and how to evaluate them is crucial.

Understanding Pearl Types
The first distinction to understand is between natural pearls and cultured pearls.
Natural pearls are extremely rare and form without any human intervention. They occur when an irritant, such as a grain of sand, enters an oyster or mollusk, causing it to secrete nacre layers around the irritant. Due to their rarity, natural pearls are incredibly valuable and often found in antique jewelry.
Cultured pearls, on the other hand, are the result of human intervention in the pearl-forming process. Farmers introduce an irritant into the mollusk, which then produces the pearl. The vast majority of pearls in the market today are cultured pearls. Despite being cultivated, these pearls are still considered genuine, as the process merely initiates what nature then takes over.
