Octagon Tanzanite and Diamond Cluster Ring
A 4.09ct natural tanzanite forms the heart of this custom cluster design, surrounded by a radiant arrangement of marquise and round brilliant natural diamonds. The ring is offered in platinum 950 with the tanzanite held in 18K yellow gold claws, or fully in 18K yellow gold.
Selected from our collection, the tanzanite is an octagon mixed cut of saturated violetish blue, its generous depth giving the colour real intensity. Marquise diamonds fan out around it like petals, interlaced with smaller round brilliants, so the ring catches the light from every angle. In platinum, the touch of yellow gold at the claws adds a subtle warmth around the stone; in yellow gold, the whole design glows, setting off the violet tones.
This design is our proposal for the stone. As a custom piece, it can be shaped around you — the cluster, band and proportions can all be refined, and the ring is made to your size. The image shown is a render of the proposed design.
You are welcome to view the tanzanite in person at our boutique, Shop 3, 82 King Street, Perth, and talk through your ring with us.
