15.39 Ct. Zircon from Tanzania

If you are searching for a singular statement gem for an engagement ring, or a rare and collectible treasure that ends the search with certainty, this Tanzanian yellow zircon from The Natural Gemstone Company is the answer you have been waiting for. This transparent oval weighs 15.39 carats, and measures 14.73 by 11.47 by 9.42 millimeters, features a mixed brilliant cut that maximizes sparkle, and carries an eye clean clarity grade as evaluated at eye level. The vivid color intensity leaps from the stone with warm golden tones, and the excellent polish means every facet returns light with lively scintillation. The gem has been heat treated to enhance its natural hue in a stable and widely accepted manner, making it an ideal choice for a bespoke engagement piece, a statement ring for special occasions, or a museum quality cabinet gem for serious collectors.

When you compare the hue and tone of this Tanzanian yellow zircon to yellow sapphires from Sri Lanka, the differences become a study in character and personality. Sri Lankan yellow sapphires often present a clean lemon to buttery tone that reads as delicate and satin like, whereas this zircon offers a richer saffron gold that feels sunlit and more opulent in body. Compared to Burmese yellow sapphires, which can trend toward pure golden to slightly greenish undertones, this Tanzanian zircon remains unequivocally warm, with a pure golden heart that favors honey and sunflower notes. When set against Brazilian citrine and golden topaz, the zircon reveals its superior brilliance and dispersion, the lively flashes of fire and internal sparkle outshining the more resinous, softer glow of typical citrine from Brazil. Cambodian and Cambodian era zircons are often celebrated for intense orange golden hues, and this Tanzanian example sits comfortably among those finest examples while maintaining a somewhat cleaner, more transparent tone that does not lean into brownish overtones.

Beyond color comparisons, the optical behavior of zircon creates another layer of distinction, and this is why collectors and gemstone lovers frequently prize Tanzanian material. The mixed brilliant cut on this oval is designed to balance face up brilliance with deep internal flashes, so the gem appears alive from every angle. That lively performance is different from sapphire and topaz, which tend to show steadier, broader flashes of light. In practical settings the excellent polish of this gem amplifies that quality, allowing the stone to command attention in both simple solitaire and more elaborate halo designs. While zircon is not as hard as corundum, the stone rewards thoughtful design choices, and our gem specialists at The Natural Gemstone Company recommend settings that provide some protection to the girdle and pavilion for pieces intended for everyday wear, such as a bezel or a protective halo, to ensure long term beauty alongside the striking presence that this 15.39 carat oval offers.

If your intent is to secure a showpiece that embodies warmth, brilliance, and provenance, this Tanzanian yellow zircon closes the chapter on a long search. Its vivid hue places it among the most desirable warm yellow gemstones in private collections, and its eye clean clarity ensures the color and fire are uninterrupted by visible inclusions. The Natural Gemstone Company stands behind the gem with detailed knowledge of its origin, enhancement history, and cut, so you can purchase with confidence when creating an engagement ring that will be spoken of for generations, or when adding a bold and luminous specimen to a serious collection. For those who want a centerpiece that feels classic and yet rare, that balances the sunlit joy of golden tones with the technical artistry of a precision mixed brilliant cut, this Tanzanian yellow zircon is a match that ends the search.
