Freshwater pearls, keshi pearls, pearl earstuds Gorgeous! Somewhere between white and silver, these pearl earstuds are small enough for everyday wear and unusual enough to be interesting. What are Keshi pearls? Keshi pearls consist of solid nacre (mother-of-pearl), and tend to have high luster as a result. Keshi pearls are small non-nucleated pearls typically formed as by-products of pearl cultivation. A Japanese word also meaning "poppy" (ケシ, 芥子), it is used in Japanese for all pearls that grew without a nucleus. Originally, keshi pearls referred to those pearls formed when a bead nucleus was rejected. More recently, keshi has been used to refer to second harvest pearls and even to freshwater non-nucleated pearls.

The more I work with pearls and learn about them, the more I value these incredible gems. The earrings come packaged in a matt white environmentally friendly presentation box, ready to be given and received with love. All my metal is from a company which is a member of the Responsible Jewelry Council. They deal only in recycled silver and gold. They smelt their metals to the highest environmental standards, to cause the least impact on the environment. They do not deal with newly mined metals, as these metals cause much greater destruction to the environment.
