1.46 Ct. Blue Sapphire from Tanzania

This 1.46 carat oval blue sapphire from Tanzania is an exceptional example of natural beauty and technical refinement, offered by The Natural Sapphire Company. Measuring 7.77 by 5.75 by 3.67 millimeters, the stone is cut in an elegant oval with a mixed brilliant faceting scheme that combines the depth and color saturation of a step-style pavilion with the scintillation and fire of brilliant cutting on the crown. The gem is transparent, with a clarity grade of slightly included when evaluated at eye level, a condition that speaks to its natural origin while allowing abundant light to pass through and reveal its vivid blue color intensity. Excellent polish ensures crisp facet junctions and superior surface luster, and critically, this sapphire is unenhanced, a rarity in today’s market where heat treatment and other enhancements are common. Origin is Tanzania, and the combination of vivid, natural color, strong polish, and an expert mixed brilliant cut creates a stone that is immediately striking whether set alone or paired with accent stones.

When compared with other sapphires available on the market, this Tanzanian specimen offers a compelling balance of visual impact, value, and natural authenticity. High-end Kashmir sapphires are renowned for their velvety cornflower blue, but they command extreme premiums and are rarely untreated; Sri Lankan sapphires often display lighter, cornflower to medium blues and can be very attractive but sometimes lack the saturation buyers seek. Many stones on the market have been heat treated to enhance color and clarity, a widely accepted practice that affects price and desirability for collectors looking for natural provenance. By contrast, an untreated Tanzanian sapphire such as this one gives you vivid color intensity and excellent polish without the hidden alterations that complicate comparative valuation. The mixed brilliant cut is tailored to maximize both depth of color and lively return of light, giving this gem a sparkle and presence that rival larger or more heavily treated stones at a similar price point, making it an excellent choice for buyers who want uncompromised natural beauty with intelligent cutting.

The heritage of corundum gemstones like this sapphire stretches back through centuries of royal and religious use, and owning an untreated blue sapphire connects you to that long history. Historically, sapphires have been prized by monarchs, clergy, and nobility for their perceived qualities of wisdom, protection, and fidelity. In many cultures blue sapphires were set into signet rings and crowns, believed to protect the wearer and confer status, and were often presented as the centerpiece of engagement and ceremonial jewelry because of their association with constancy and trust. This Tanzanian blue carries that same lineage, its vivid hue and natural origin echoing the unaltered, heirloom-quality stones passed down in families and institutions for generations. Choosing an untreated stone from The Natural Sapphire Company means selecting a gem that resonates with that tradition, offering not just a beautiful object but a meaningful link to the symbolism and ceremonial uses that have elevated blue sapphires above ordinary gemstones for centuries.

From a practical and design perspective, this sapphire’s dimensions and cut make it extremely versatile. At 7.77 by 5.75 by 3.67 millimeters, it suits classic solitaire engagement settings, halo designs that amplify perceived size and sparkle, or elegant pendant and earring applications where its vivid color will take center stage. The mixed brilliant cut brings out both scintillation and depth, and the excellent polish means minimal post-setting finishing is required, preserving the cutter’s intent. Slight inclusions visible at eye level are common in natural sapphires and, in many cases, add character without diminishing optical performance; they also serve as natural fingerprints that confirm authenticity and rarity compared with fully flawless, heavily treated stones. For buyers who value long-term resale value and historical integrity, an untreated Tanzanian sapphire often retains desirability because it avoids the question marks that accompany treated material. The Natural Sapphire Company’s sourcing practices emphasize traceability and quality, and this gem is selected to meet standards of ethical procurement and enduring aesthetic appeal.
