About ONTOO

Born from Martina Baeriswyl-Holzach’s lifelong passion for fine jewelry and fashion, ONTOO blends timeless design with modern versatility. Raised in Argentina with Swiss roots, Martina was inspired by her mother’s collection of antique jewelry and gemstones — a love that grew into a vision for everyday luxury.

Every ONTOO piece reflects her belief that true elegance is effortless, versatile, and lived. From refined jewelry to sophisticated fashion, the brand celebrates individuality and a lifestyle of comfort and timeless beauty.
