marahlago's Keetah Necklace is made of highly polished sterling silver, Larimar stone, black mother-of-pearl and red agate – unique, beautiful and sure to draw attention. Larimar is prized for its deep, Caribbean-Ocean-blue color and is the result of an intense-heat and crystallizing volcanic process. Washed down to the beach by runoff, these gems are found only in the Dominican Republic. A Peace Corps worker found the unique and lovely stones in 1974 and, because no two are exactly alike, they are prized by jewelers. Adjustable slider chain. Chain length: 22". Pendant: 1"Lx 1/2"W.
