Why This Gemstone Captivates

Monumental Visual Presence

With a length of over 14 mm, this Zircon possesses a massive “face-up” size that rivals stones of much higher carat weights. Its elongated oval proportions make it the ultimate candidate for a high-jewelry statement pendant or a singular, regal cocktail ring that elongates the finger beautifully.

The “Portuguese” Optical Advantage

Zircon is world-renowned for its high refractive index and double refraction, giving it a brilliance often compared to a diamond. By applying a Portuguese Cut—featuring two rows of rhomboidal and three rows of triangular facets—this stone creates a breathtaking “kaleidoscope” effect. The $7.1\text{ mm}$ depth ensures that light is trapped and dispersed in a relentless shower of red sparks.

The Tanga Heritage

Tanzanian Zircons are highly sought after by collectors for their rich, organic saturation. This 10.38ct specimen displays a velvety, deep red—free from the overly dark tones found in lesser material—ensuring it remains vibrant and lively even in ambient indoor lighting.

Design & Care Recommendations

• Metal Pairing: The fiery red of this Tanzanian gem is elevated beautifully by 18k Yellow Gold for an opulent look, or Platinum to provide a sharp, modern contrast.

• Setting: To protect the precision-cut facet edges, we recommend a secure multi-prong or basket setting that allows light to enter from the sides, maximizing the stone’s natural fire.
