With over 20 years of experience and a passion for travel, Martha and Kathy create bespoke jewelry with curated gemstones from their adventures around the world. Martha lived in Brazil for over 15 years and her travels have taken her to various mining regions within Brazil, South Africa, and the Far East to examine and handpick the gemstones for the Aria Collections. Kathy lives by the motto, "Go Big or Go Home," and fell in love with jewelry design when she met founder Hans Stern, a pioneer in designing jewelry with Brazil's vibrantly colored gemstones, Mr. Stern invited her to his workroom, shared his expertise - and she was hooked. Martha and Kathy met while living in Rio de Janeiro and they have been design partners and friends ever since.
