0.62 Ct. Alexandrite from Brazil

One beautiful transparent 0.62 carat oval shape alexandrite from Brazil, with dimensions of 6.78 x 4.82 x 2.61 mm, presents a textbook example of why alexandrite remains one of the most sought after collector gems. This gem exhibits a remarkable green to purplish red color change, a defining characteristic of fine alexandrite, with vivid color intensity and excellent polish. The cut is a mixed brilliant, combining a faceted crown that maximizes scintillation with a carefully proportioned pavilion that channels light back through the table for strong face up color. The clarity grade is very very slightly included, evaluated at eye level, which means that to a trained eye the stone reads as clean and transparent under typical viewing conditions, while small internal features attest to its natural origin. No enhancement has been applied, and the Brazilian provenance is significant for buyers who value traceable origin and the known geological signatures of South American alexandrite deposits. The Natural Gemstone Company proudly presents this stone with full disclosure of its characteristics and with the confidence that comes from years of dealing in fine natural gemstones.

The geometric faceting of this oval alexandrite is central to its visual appeal, and the mixed brilliant design has been executed to allow maximum light play. The interplay between large, well polished crown facets and a complex pavilion with smaller precision facets creates an active surface of mirrors that both diffuse and concentrate light. Under fluorescent lighting the green side of the color change is lively and vivid, with multiple bright flashes and a strong green saturation across the table. Under incandescent lighting the stone shifts to a rich purplish red with warm flashes that reveal depth and body color. The facet junctions and symmetry are calibrated to enhance pleochroism and color change, so that each movement of the gem or change in light source yields a different pattern of highlights and tonal shifts. For the educated buyer this is not mere flash, but evidence of intentional cutting to balance color, brilliance, and the modal optical properties of alexandrite, resulting in an object that rewards close viewing and repeated wear.

Clarity and polish are important technical factors that influence both aesthetic appeal and market value, and this alexandrite performs exceptionally well on both counts. The very very slightly included clarity grade indicates that inclusions, where present, are minor and do not detract from the jewel if viewed in normal conditions. Inclusions are often useful to gemologists and collectors because they confirm natural origin, and in alexandrite they can be characteristic of the growth environment that produced chromium bearing chrysoberyl. The polish is described as excellent, meaning facet surfaces are smooth and reflective, minimizing light scattering and preserving crisp facet junctions that are essential for sharp brilliance. Given that this stone has received no heat treatment or other enhancement, and given the Brazilian origin which is associated with certain trace element signatures, the gem stands as an honest natural specimen that appeals to connoisseurs who prioritize untreated material and transparent provenance.

For practical use and long term enjoyment this alexandrite is well suited to fine jewelry settings that show off its color change and geometric faceting. Set as a solitaire ring, the oval outline and mixed brilliant faceting present a lively face up appearance that will catch daylight and evening light in distinct and attractive ways. A secure prong or partial bezel setting will allow light to enter the crown and reflect from the well polished pavilion, preserving the dynamic color change and scintillation. Collectors and designers will also appreciate that the dimensions and proportions produce an elegant spread on the finger or pendant, while the uncompromised clarity and polish support close inspection without disappointment. The Natural Gemstone Company stands behind the description of this stone and can provide additional photographs of the gem under different lighting, as well as a professional report upon request. For buyers seeking a rare, natural, and visually engaging alexandrite, this Brazilian oval, with its vivid color change, expert faceting, very very slightly included clarity, and no enhancement, represents a compelling and well documented choice.
