3.66ct Tanzanite & Diamond Cluster Ring – 18ct White Gold

Product Details
An exceptional tanzanite and diamond cluster ring, centred on a striking oval mixed-cut tanzanite displaying a rich, highly saturated blue-violet colour. The gemstone exhibits excellent depth of colour and is secured in a classic four-claw setting, forming the focal point of this elegant and eye-catching design.

Surrounding the centre stone is a beautifully proportioned cluster of twenty-four round brilliant-cut diamonds, arranged in a refined oval three-row formation. The diamonds are claw and grain set, creating a continuous halo of brilliance that enhances the vibrancy and depth of the tanzanite.

The head flows seamlessly into tapering shoulders and a plain polished shank, offering a balanced and comfortable fit. The overall design combines timeless cluster styling with a bold and luxurious presence on the hand.

Crafted in white gold, the ring is stamped “18K” and has been professionally tested as 18ct white gold. The construction is solid and well-proportioned, ensuring durability alongside refined aesthetics.

Investment & Rarity
Fine tanzanites of this size and colour are becoming increasingly scarce, particularly those displaying strong saturation and attractive blue-violet tones. As tanzanite is mined from a single location, supply remains limited, adding to its long-term desirability.

Cluster rings combining a substantial tanzanite centre stone with a well-matched diamond surround offer both visual impact and collectability, making them highly sought after among collectors and jewellery enthusiasts alike.
