Astrid and Jacob are both degreed geologists and began their journey together while living in Rio de Janeiro, Brazil. Their love for exploration led them to prospect throughout Minas Gerais and Rio Grande do Sul. Moreover, their passion for discovery took them through far-flung villages in the remote countryside. Whether they were lost in the jungle searching for aquamarine or narrowly escaping gun-toting pistoleros in the dried-out Rio Doce river basin, they often encountered the good-natured hospitality of kind-hearted miners and their families.

In each adventure, they brought donations of backpacks filled with clothes, and sometimes even fresh chicken for those who primarily lived off fruits and vegetables. As a result of these goodwill gestures, they were introduced to family or friends in other parts of Brazil. They directly source and offer through KRS Alligator Quartz, Amethyst, Apatite, Aquamarine, Calcite, Emerald, Imperial Topaz, Muscovite, the famed Tourmalines from Aricanga and Chia mine and countless other unique and fine mineral specimens!
