1.40 Ct. Spinel from Tanzania

One beautiful transparent 1.40 carat cushion shape blue spinel from Tanzania receives our highest regard at The Natural Gemstone Company, for its timeless presence and its direct link to the ancient stories of gem collecting. Measuring 6.86 x 6.10 x 3.95 mm with a mixed brilliant cut, this gem presents a balance of fire and deep, even color that evokes classic jewels passed down through generations. The clarity is very slightly included when viewed at eye level, preserving the gems integrity while allowing the surface and internal facets to sing with light, and an excellent polish brings a mirror like finish to every facet. No enhancement has altered this spinel, a fact that speaks to authenticity and natural origin, and its intense color intensity sets it apart as a specimen meant for a collector or an heirloom commission. In the long lineage of blue gemstones that have defined dynasties and marked milestones, this Tanzanian blue spinel stands with quiet confidence, offering the sense of history associated with stones that have survived centuries unaltered, and the cushion form recalls the soft geometry of antique jewels favored by royalty.

Comparisons to more familiar famous sources can help place this stone in the broader palette of blue gems, and here this spinel shows its particular character. Against a Kashmir sapphire the spinel displays a cooler clarity and less velvety diffusion, the Tanzanian blue offering a crisper, more transparent blue that carries light through the stone rather than holding it in a soft glow. Compared to Sri Lankan sapphires the color here is often deeper and more saturated, while Ceylon stones tend to be lighter and more brilliant in tone. When set beside Burmese spinels the Tanzanian example can seem more stable in tone, whereas some Burmese stones carry warmer or purplish hints. Australian and Montana sapphires tend toward inky and denim blues, and this Tanzanian spinel reads as cleaner and more jewel like, with an intensity that is immediate yet refined. Collectors familiar with Vietnamese and Afghan spinels will recognize the family resemblance, yet this stone maintains a signature Tanzanian coolness and a crystalline transparency that is rare in similarly hued examples.

For those who cherish lineage and legacy in their jewels, this blue spinel lends itself to settings that honor history, such as a low bezel in warm gold for a Victorian inspired look, a classic four prong in platinum for a modern collectible talisman, or a halo composition that echoes period brooches and rings. The mixed brilliant cut contributes scintillation from the crown, while the cushion outline preserves the visual weight that makes 1.40 carat appear both substantial and graceful on the hand. Origin documentation from Tanzania and the lack of enhancement provide assurance of provenance and natural beauty, values that resonate with clients who see gemstones as more than adornment. The Natural Gemstone Company is proud to present this Tanzanian blue spinel as a bridge between the old world of gemstone lore and the contemporary desire for genuine, enduring beauty, a stone crafted by nature and cut for a future that will treasure it as a family legacy.
