Yellow Sphene Emerald Cut Gemstone, 7x5mm High Fire Gem, Natural Loose Ring Stone, Custom Fine Jewelry Gem

Blazing with intense golden-yellow body color and intense spectral fire, this 1.35 Carat Natural Sphene (Titanite) brings extraordinary optical brilliance straight to your workbench. Precision-cut into a classic 7.2 x 5.1 mm Emerald shape, this gem offers bench goldsmiths and custom studio designers a near-7x5mm calibrated footprint that seats smoothly into standard rectangular or emerald-cut mountings.

Mined in Pakistan, this gem displays sphene’s signature optical dispersion rating of 0.051—substantially higher than diamond—causing light to split into dazzling flashes of red, orange, and green fire across its step-cut facets. With a well-proportioned 4 mm pavilion depth, light enters freely to produce vibrant scintillation. It serves as a captivating centerpiece for custom rings, alternative bridal designs, or unique collector showpiece jewelry.
