0.71 Ct. Alexandrite from Brazil

This alexandrite offered by The Natural Gemstone Company is a transparent round gem with a weight of 0.71 carat and compact dimensions of 5.33 x 5.25 x 3.67 mm, the stone displays a classic round silhouette with a mixed brilliant cut and an excellent polish, the cut maximizes light return and supports the gems notable color change from green in daylight to purple under incandescent light, the combination of intense color intensity and natural transparency gives the stone an immediate presence that belies its modest carat weight, the gem is untreated with no enhancement and originates from Brazil, the clarity is graded slightly included when evaluated at eye level which allows the stone to present as both visually clean and verifiably natural.

The physical size and clarity of this alexandrite make it particularly well suited for use as a statement piece, at 5.33 mm diameter the gem occupies a scale that reads clearly from a short distance while still integrating comfortably into wearable designs, the 0.71 carat weight provides enough mass to articulate strong color and light performance when set in a solitaire mounting, in a halo or three stone composition the intense color and mixed brilliant facet arrangement will remain the focal point, the slightly included clarity grade means that inclusions are present but not dominant at normal viewing distances, these subtle internal characteristics preserve transparency and contribute to the gems natural identity without diminishing surface brilliance.

Color change is the defining attribute of alexandrite and this example shows that behavior with intensity and depth, under neutral or fluorescent lighting the stone presents as a deep green with bluish undertones and vigorous saturation, under incandescent or warmer lighting the same stone shifts to a rich purple with a velvety character, this pronounced transition is evidence of chromium related absorption and of the gemological character that collectors and makers prize, the intense color intensity enhances the perceived size and presence of the stone because stronger color concentrates visual impact, the excellent polish and mixed brilliant cutting geometry aid both the color transition and the overall scintillation making the gem read as lively and substantial in most mounting orientations.

From a practical design and care perspective the stone benefits from settings that expose the table to light while offering protection to the girdle and pavilion, a four or six prong head will emphasize the gem as the central element while allowing light to travel through the pavilion faceting, a halo can add apparent diameter and contrast to further emphasize the color change and presence, for daily wear a bezel with slightly raised prongs will protect the girdle while preserving the statement quality in a ring or pendant, buyers and designers working with The Natural Gemstone Company will find the unenhanced Brazilian origin and the clearly reported dimensions and clarity useful for certification and appraisal, professional cleaning with warm soapy water and careful inspection for loose settings will keep the gem performing optimally, additional documentation and high resolution viewing images are available on request.
