This 1960 Art Deco Revival cluster ring is made from platinum and features a central oval-cut blue tanzanite. The blue gemstone sits within a milgrain-edged halo comprising round brilliant-cut diamonds and two square princess-cut diamonds, complemented by brilliant-cut diamonds along the split shoulders. The platinum band has full UK hallmarks for platinum 950 and weighs 6.0 grams in total. It measures 1.5 cm high, 1.3 cm wide, and 2.2 cm deep. Designed for personal wear, the ring serves as an elegant jewellery piece suitable for daily adornment or special occasions. The bright white diamonds contrast with the blue tanzanite and the polished silver-coloured metal. The handcrafted setting incorporates fine milgrain detailing around the stones and secure rub-over mountings. Full hallmarks appear on the interior of the shank to verify the metal purity. The ring functions as a wearable finger ornament within a modern wardrobe.

FAQs

A tanzanite cluster ring is a piece of fine jewellery featuring a central tanzanite gemstone surrounded by a grouping of smaller gemstones, typically diamonds, arranged to enhance light reflection and visual scale.

High-grade tanzanite rings are commonly set in platinum or white gold to complement the cool blue-violet hue of the gem, alongside natural diamonds for contrast.

Authentic tanzanite exhibits strong pleochroism, displaying different shades of blue and violet depending on the viewing angle, and is typically documented by a gemmological certificate.

A tanzanite cluster ring serves as a focal accessory that pairs effectively with minimalist evening wear or crisp tailored attire to highlight the blue gemstone.

Tanzanite should be cleaned using warm water, mild liquid soap, and a soft brush, avoiding ultrasonic cleaners and harsh chemical solutions to prevent gemstone damage.
