0.84 Ct. Alexandrite from Brazil

This listing describes a single transparent alexandrite from the holdings of The Natural Gemstone Company, weighing 0.84 carat, presented in an elegant marquise shape. The gem measures 8.84 x 4.49 x 3.22 mm, and it has been fashioned with a mixed brilliant cut to balance sparkle and color. Clarity is graded as slightly included when evaluated at eye level, and the polish is excellent, allowing light to pass cleanly through the pavilion and crown facets. There has been no enhancement to alter color or clarity, and the stone is of Brazilian origin, a source known for producing alexandrite specimens with strong color change properties. The piece displays vivid color intensity, shifting from a clear green under fluorescent or daylight conditions to a pronounced purple to red under incandescent lighting, and the mixed brilliant pavilion supports these changes by returning both dispersion and flash in varied lighting.

Optical behavior is a defining attribute of this alexandrite, and the mixed brilliant cut is chosen to emphasize both the gem's color and its internal light interactions. The marquise outline creates a graceful silhouette that can be set to visually elongate a finger, and the faceting conveys a balance between broad color faces and scintillation from smaller brilliant facets. The clarity grade of slightly included indicates the presence of minor natural features that are visible under magnification but only marginally apparent to the naked eye. These internal characteristics are typical for natural alexandrite and do not detract from the gem's overall appearance. The vivid color intensity means that the green and purple hues appear saturated and distinct, rather than weak or murky, and the excellent polish enhances surface brightness while minimizing light leakage.

Durability is an important consideration for any colored gem intended for daily wear, and alexandrite, which is a variety of chrysoberyl, offers substantial resistance to scratching and abrasion. On the Mohs hardness scale alexandrite is approximately 8.5. For context, diamond is 10, corundum varieties such as sapphire and ruby are 9, topaz is 8, and quartz is 7. This position on the Mohs scale places alexandrite well above many common gem materials, offering strong long term durability in rings and other jewelry that experiences regular contact. The nature of the marquise cut requires attention to the two pointed ends when choosing a setting, and practical mounting options include protective bezel settings or well executed prong settings that secure and shield the points. Routine care should avoid extreme impact, and cleaning with warm soapy water or an ultrasonic cleaner is generally safe for alexandrite that has no treatments, though professional inspection is recommended if inclusions are known to be near facet junctions.

Provenance and responsible sourcing form an integral part of the offering from The Natural Gemstone Company. This alexandrite is accompanied by documentation of natural origin and a statement of no enhancement, reflecting transparency in its supply chain and treatment history. The gem suits a variety of fine jewelry applications including solitaire rings, elegant pendants, and bespoke designs where the color change phenomenon can be highlighted. Given its vivid color change, mixed brilliant faceting, and compact marquise proportions, the stone works especially well where alternating light environments will be visible, such as pendants worn outdoors or rings that move between daylight and indoor lighting.
