0.62 Ct. Alexandrite from Tanzania

This 0.62 carat oval alexandrite from Tanzania is a rare and refined example of what serious collectors seek, transparent and showing the classic greenish to orangish color change that defines true alexandrite. Measuring 5.40 by 5.14 by 2.92 mm, this stone is cut in a mixed brilliant style that maximizes sparkle while preserving weight and depth. Its clarity grade is very slightly included evaluated at eye level, a level of transparency and eye appeal that is unusual for natural alexandrite at this size. The color intensity is described as intense, and the polish is excellent, giving clean, lively facets and a surface that catches light with crisp fire. Importantly, this gem has received no enhancement, which means you are acquiring a completely natural color change gem, straight from its Tanzanian origin, with geological character and integrity that treated or synthetic stones cannot match.

When compared with other market options, this alexandrite stands out on several fronts. Many alexandrites under one carat are heavily included, weak in color change, or have been subjected to enhancements to improve appearance. Lab grown alexandrites offer predictable color and clarity, but they lack the rarity, natural formation history, and collector appeal of a natural specimen. Other natural alexandrites from classic sources like Russia can command premiums for historical provenance, while stones from Sri Lanka and Brazil often exhibit paler or less dramatic color change. This Tanzanian stone strikes a balance between dramatic color change and excellent clarity, while remaining unenhanced, which gives collectors confidence in long term value and desirability. In terms of value, natural, unenhanced, intensely colored alexandrite in an attractive mixed brilliant oval cut offers stronger upside than many similarly sized treated or synthetic alternatives.

From a connoisseur perspective, the mixed brilliant cut of this 0.62 carat oval is a decisive advantage for wearable high end jewelry and display in a collection. The mixed brilliant proportions combine the scintillation and light return of a brilliant facet arrangement with the elegant oval outline that flatters ring and pendant designs. Excellent polish ensures the stone presents with crisp facet edges and minimal surface disturbance, enhancing perceived clarity and brilliance. The very slightly included clarity grade evaluated at eye level means that inclusions do not interfere with the gem s visual charm, while still affirming its natural origin. Collectors who compare stones often find that eye clean or near eye clean natural alexandrites at this size and color intensity are scarce, and those that are heavily included or fracture filled do not offer the same aesthetic or resale potential. Choosing an unenhanced, intensely colored, well cut specimen reduces common tradeoffs and places this gem among the top tier of small natural alexandrites available today.

Purchasing this alexandrite from The Natural Gemstone Company gives you access to careful sourcing and transparent provenance, attributes that matter to serious collectors. Tanzania has emerged as a significant source of strong color change alexandrite, and this piece exemplifies the best of that material, combining a notable color shift, durable mixed brilliant cut, and a natural state with no enhancement. For a high end gemstone collection, this alexandrite offers rarity, visual drama, and investment appeal, because natural, unenhanced color change stones with intense saturation and good clarity remain in demand among both collectors and jewelry connoisseurs. Whether set as a signature stone in a bespoke piece or preserved as a highlight in a collector s cabinet, this gem will stand out beside synthetics, treated stones, and more common gemstones, serving as a meaningful and enduring addition to a refined collection.
