Ostasz Studio, based in New York City, operates in the retail luxury jewelry sector, providing design and manufacturing support for leading houses in New York and around the world. Each piece begins with a seed—whether a distinctive gemstone or a personal concept—that requires collaboration among experts to realize as a wearable, desirable creation. Its objective is to produce pieces whose worth exceeds the materials, reflecting craftsmanship that can be enjoyed across generations. Private clients are encouraged to participate in the design process to ensure the final piece fits their lifestyle and wardrobe. Jewelry experts and stylists are on hand to guide projects toward both immediate appeal and long-term value. Premium diamonds and collector-grade colored gems are sourced as needed, and every stage of production is handmade on site.
