Eons ago, heat and pressure from volcanic activity crystallized Larimar gemstones. They remained undiscovered on a Caribbean island until a Peace Corps volunteer came upon a deposit of the marbled, ocean-blue gems in 1974. Experience the breathtaking allure of brilliant Larimer with this sterling-silver-accented heart pendant. Sterling silver band. Pendant dimensions: .6"W x 1"H with 18" adjustable slider chain.
