Freshwater Pearls 101

Freshwater pearls show up across so much of our collection, but a lot of people aren't sure what actually makes them different from other pearls — or why no two are exactly alike. Here's the quick version.

Where they come from

Freshwater pearls are cultivated in freshwater mussels, primarily in lakes and rivers, as opposed to saltwater pearls (like Akoya or Tahitian), which grow in oysters in the ocean. A single freshwater mussel can produce multiple pearls at once, which is part of why freshwater pearls are more accessible than their saltwater counterparts without sacrificing the natural, organic look people love.

Why no two pearls are identical

Because freshwater pearls are grown by a living organism, each one forms with its own subtle variations in shape, size, and luster. Some are nearly round, others are slightly baroque or irregular — and that's part of the appeal. A strand or bracelet of freshwater pearls has a handmade, organic quality that perfectly matched, machine-uniform beads simply don't have.

What to look for in quality

Luster — the way a pearl reflects light — is the biggest indicator of quality. A high-luster pearl has a bright, almost mirror-like sheen, while lower-quality pearls look chalky or dull. Shape matters too, but a slightly irregular, high-luster pearl is often more desirable than a perfectly round, dull one.

Caring for freshwater pearls

Pearls are softer than most gemstones, so they deserve a little extra care. Put them on last, after perfume and lotion, and take them off first before showering or swimming. Wipe them with a soft, damp cloth after wearing, and store them separately from harder jewelry that could scratch the surface.

How we use them

You'll find freshwater pearls throughout our stacking bracelets and Ensembles pieces, usually paired with 14k gold plated beads and findings for a look that feels coastal without being costume-y.
