0.43 Ct. Alexandrite from Russia

Deep beneath the ancient folds of the Russian Ural Mountains, where heat and pressure have shaped the bedrock for millions of years, this alexandrite began its long journey. Chrysoberyl crystals, rare and stoic, grew slowly within metamorphic pockets, capturing traces of chromium that would one day give this stone its signature magic. As light changed across the sky, chromium atoms bent wavelengths in a way that makes alexandrite appear greenish in daylight, and purplish under incandescent glow. The stone you see now carries that original earth story, a tale of geological patience and elemental chemistry that is visible every time the gem shifts color on the finger or in a pendant. This particular specimen, transparent and weighing 0.43 carat, is a direct link to those mineralogical origins, a small but vivid fragment of deep time that has been brought forward for modern admiration.

When the rough was brought up from the Ural mines, expert lapidaries selected the clearest piece available, mindful of the balance between size and optical performance. The result is an oval shaped gem with precise dimensions of 5.34 x 3.97 x 2.70 millimeters. It was fashioned into a mixed brilliant cut to maximize both scintillation and the subtle color change that defines high quality alexandrite. At eye level the clarity reads slightly included, a testimony to authentic natural formation rather than artificial treatment. The color intensity is medium, providing vivid greenish tones in daylight and a compelling purplish cast in warmer light sources. The polish is excellent, the facet junctions crisp, and there has been no enhancement applied to alter its natural beauty. Origin verified as Russia, this alexandrite arrives to you as a responsibly sourced natural treasure, with its story intact from mine to gemstone.

Skilled hands and patient eyes translated the rough into a jewel ready for daily life, not a fragile museum piece. Chrysoberyl is known for its notable hardness, registering 8.5 on the Mohs scale, which gives this alexandrite strong resistance to scratches from common materials encountered in everyday wear. It also has good toughness, meaning it resists breaking and chipping better than many other colored gemstones. Unlike gems with prominent cleavage, this stone lacks planes of weakness that can split under impact, making it particularly suitable for rings, bracelets, pendants, and everyday earrings. For the most secure everyday setting, I recommend a bezel or a well designed prong setting that offers protection to the girdle while allowing light to interact with the mixed brilliant facets. Avoiding extreme blows is still sensible, as with any fine jewelry, and routine checks of the setting will help preserve the gem for years of continuous wear.

At The Natural Gemstone Company we celebrate gemstones that carry both geological provenance and human craftsmanship. This alexandrite is more than a beautiful object, it is a living narrative that moves with you from day to night, shifting from greenish to purplish as light changes, while standing up to the demands of daily life. Care is straightforward, warm soapy water and a soft brush will safely remove everyday oils and dust, and a gentle professional inspection every year will ensure fittings remain secure. Because this gem is natural and slightly included at eye level, I would advise avoiding aggressive ultrasonic cleaning on pieces that have visible internal features, and to refrain from exposing the stone to strong acids or prolonged high heat. Set in a thoughtful design, this 0.43 carat oval alexandrite can become a daily companion and an heirloom, a finely polished reminder of the Ural Mountains and of nature s ability to create color and complexity.
