0.64 Ct. Alexandrite from Brazil

When you are searching for a single stone to stop your search, whether for an engagement ring that will be admired for decades, or for a collector piece that exemplifies rarity and honest provenance, this 0.64 carat emerald cut alexandrite from Brazil answers that call with confidence, and presence. This gem measures 5.98 x 4.18 x 2.76 mm, it is transparent, eye clean at face up inspection, and shows intense color with an excellent polish, all without any enhancement, which means the beauty you see is the natural brilliance of the stone itself. At The Natural Gemstone Company we know buyers who value authenticity and spectacle, and this alexandrite delivers both, shifting from a rich green under fluorescent lighting to an evocative purple under incandescent light, a trait that is as thrilling in a quiet setting as it is in sunlight or candlelight. The emerald cut gives this stone a refined and elegant silhouette, a series of broad parallel facets that emphasize color saturation and clarity, which makes the color change more dramatic and legible to the eye, and the clean facets and refined proportions ensure that each transition of color reads clearly and beautifully, whether set as a solitaire for a proposal, or housed in a collector cabinet alongside other rare gems.

To appreciate how this alexandrite reflects and returns light, it helps to compare it with other gemstones in its category, and with other color change stones. Alexandrite, as a chrysoberyl species, tends to favor color response over sparkling fire, and in this emerald cut example the light is handled with a disciplined and dignified voice rather than a chorus of tiny flashes. Compared with brilliant cuts in sapphires or in color change spinels, which use a multitude of small facets to throw scintillation and lively sparkle, this emerald cut alexandrite offers broad, satiny flash and a sumptuous, even face up color that emphasizes the stone character more than bling. Against emeralds, which are prized for saturated green and have a typically oily or velvety luster when clean, this alexandrite shows a cleaner, crisper transmission of light and a more dynamic personality because of the color change, while most emeralds will not exhibit that dramatic shift between green and red or purple. Compared with alexandrites cut as cushions or ovals, which can maximize brilliance, the emerald cut in this piece creates flat planes of color that make the change of hue read like a theatrical scene change, with deep green curtains sweeping to regal purple under warmer light. The excellent polish intensifies surface reflection, giving attractive mirror like facets along the step cuts, and because the clarity is eye clean, there are no internal distractions to mute the color response, so the light is free to travel and return as pure color rather than fractured brilliance.

If your priority is a stone that tells a story every time you look at it, that will stand out on a hand or in a collection for its natural provenance and honest presentation, this alexandrite is a perfect fit. Its 0.64 carat weight and the elegant proportions of the emerald cut make it versatile for fine jewelry, lending itself to a simple bezel for modern minimalists, or a classic four prong mounting that lets the light work its magic under both daylight and evening light. The fact that it is unenhanced and from Brazil adds to its collectible appeal, bringing traceable origin and a natural history that matters to discerning buyers. At The Natural Gemstone Company we recommend settings that allow both top light and side light to enter the pavilion, because that encourages the most dramatic color change, and because the step facets reward thoughtful metal work with bold, consistent flashes of color. If you are seeking an engagement stone that combines get noticed understatement with a private display of wonder, or a collector gem that will become a reference example in your cabinet, this emerald cut green to purple alexandrite delivers rare optical character, enduring durability, and the honest provenance that assures you are making a considered and beautiful choice.
