Why This Gem Is Extraordinary

The “Power” Cushion

While many large zircons are cut into ovals, a perfectly symmetrical 13mm square cushion is a rarity. This shape provides a modern, high-fashion appeal while offering a massive face-up presence that makes it the ultimate candidate for a high-jewelry cocktail ring or a singular statement pendant.

Architectural Brilliance

The Portuguese Cut is the secret to this stone’s life. With a depth of 7.7 mm and multiple rows of rhomboidal and triangular facets, the light is trapped and bounced internally to create a “kaleidoscope” of crimson fire. Because Zircon is doubly refractive, every facet appears doubled to the eye, resulting in a dense, honeyed brilliance that other red gems simply cannot match.

Tanga’s Signature Red

Tanzanian Zircons are world-renowned for their “earth-born” saturation. This 13.73ct specimen displays a deep, regal red—free from the overly dark “brownish” tones often found in lesser material. It maintains its vivid, fiery personality even in low-light environments.

Design Inspiration

This stone’s substantial $13\text{ mm}$ footprint demands a setting of equal caliber. We recommend 18k Yellow Gold to pull out the warm, fiery undertones, or surrounding it with a halo of colorless diamonds to create a sharp, dramatic contrast against the saturated red center.
