The Lure of Larimar Those who wear Larimar are sure to hear, "What is that beautiful stone?" Because of its rarity, few people have ever seen Larimar-It comes from a remote mountain in the Dominican Republic....on a single kilometer to be exact. Twenty times rarer than tanzanite it is one of the world's rarest gemstones. To look upon Larimar is to see the swirling seas of the Caribbean captured in an ocean's palette of blues and greens. Quality stones are difficult to obtain, and Marah Lago mines only the best: each stone hand-picked and polished to evoke the luscious range of color and variation unique to each stone. Lucky for us, Larimar's volcanic heritage gives Larimar a powerful strength and durability. Nature also ensures that no stone is alike. Marah Lago settings are designed to celebrate the distinctive hues, patterns and natural wonder of each beautiful gem.
