What Are Pearls? A Brief Overview
Before we get into the differences between saltwater and freshwater pearls, it’s important to understand what pearls actually are and why they’re so special.
Natural vs Cultured Pearls
Pearls are remarkable because they’re the only gemstones created by living organisms—oysters or mussels.
-
Natural Pearls: These are formed without human intervention, which makes them extremely rare and highly valuable. Natural pearls have a unique charm, but finding a flawless natural pearl is like finding a needle in a haystack.
-
Cultured Pearls: Most pearls on the market today are cultured. This means humans introduce an irritant into the oyster or mussel to stimulate pearl formation. Cultured pearls can be carefully nurtured to produce desired shapes, colors, and sizes, making them more accessible while retaining natural beauty.
How Pearls Are Formed
Pearl formation begins when an irritant—like a grain of sand—enters an oyster or mussel. The mollusk secretes nacre, a combination of aragonite and conchiolin, around the irritant, layer by layer, until a pearl is formed.
-
Saltwater Pearls: These grow inside oysters found in oceans and seas.
-
Freshwater Pearls: These develop in freshwater mussels, typically in lakes and rivers.
The environment in which the mollusk lives—saltwater or freshwater—greatly influences the pearl’s luster, shape, and overall beauty.
Saltwater Pearls: The Luxurious Choice
