Cosmos Necklaces — Recalling the Nature Beauty of Cosmos in Bloom with Sapphire, Garnet and Paraiba Tourmaline

Cosmos Collection

Inspired by the elegance of the cosmos flower, this collection celebrates nature’s delicate beauty through vivid gemstones and masterful craftsmanship. Each piece is designed with a centre stone of Blue Sapphire, Yellow Sapphire, or Green Garnet, chosen for its vibrant colour and brilliance. Surrounding the centre gem is a halo of melee Paraíba Tourmalines, their rare neon glow adding a striking contrast, while marquise-cut diamonds form graceful petals that complete the floral silhouette.

From Left to Right:

Platinum / Blue Sapphire, Paraiba Tourmaline & Diamond.

Handcrafted in Japan, the Cosmos Collection blends refined techniques with a painterly approach to colour. The result is a timeless design that evokes the charm of a flower in full bloom—a perfect choice for collectors and those who love jewellery inspired by nature’s artistry.
