Blister pearl earrings highlight the natural dome shape that forms when a pearl grows against the inner shell of a mollusk. Unlike round pearls, blister pearls (also called mabe pearls) develop flat on one side, creating a half-sphere silhouette that sits close to the earlobe. Each pearl in this collection is set in .925 sterling silver and shows the iridescent nacre layers the oyster deposited over months or years.

A blister pearl grows attached to the inner shell of a mollusk rather than free-floating in tissue. This produces a dome shape with a flat back, often called a mabe pearl after processing.
Wipe pearls with a soft, damp cloth after wearing and store them separate from harder gems. Avoid contact with perfume, hairspray, and household chemicals, which can dull nacre over time.
Blister pearls rate 2.5 to 4.5 on the Mohs hardness scale, similar to other pearl types. They handle daily wear well in earring settings because earrings receive less impact than rings or bracelets.
