3.05 Ct. Spinel from Tanzania

This transparent 3.05 carat pink spinel presents a radiant shape with dimensions 10.14 x 6.34 x 4.85 mm and a precise radiant cut. Clarity is graded very slightly included when evaluated at eye level, and the gem displays a medium intense pink color with an excellent polish. The material is untreated with no enhancement and originates from Tanzania, a source recognized for fine pink spinel deposits. Physically the stone benefits from spinel s isometric crystal system and a relatively high refractive index near 1.72, properties that promote uniform light behavior through the crystal and minimize color zoning, while its toughness and polish preserve facet crispness over time.

The exceptional sparkle of this spinel arises from the interaction of its intrinsic optical properties and the geometry of the radiant cut. As an isotropic material, spinel does not exhibit double refraction, so light entering the gem is returned in a consistent and predictable way, enhancing return of both broad flashes of color and fine scintillation. The radiant cut employed here combines well proportioned step and brilliant style facets that create multiple internal reflection pathways, allowing the stone to trade flashes of brilliance with evenly distributed sparkle across the table and pavilion. The medium intense pink hue provides strong contrast between light and shadow within the facets, and the very slightly included clarity ensures that light paths remain largely unobstructed, producing crisp brightness rather than muted diffusion. Excellent polish further amplifies surface reflectivity, so each facet edge acts as a clean mirror to the light. Purchased through The Natural Gemstone Company, this Tanzanian pink spinel exemplifies how careful cutting and the stable optical framework of spinel produce an energetic and enduring scintillation that is distinct from many other gem species.
