3.60 Ct. Alexandrite from Brazil

This is a beautiful, transparent alexandrite weighing 3.60 carat, presented in an elegant oval shape with dimensions of 10.78 x 7.82 x 4.65 mm, cut and polished by master cutters to emphasize both color and brilliance. The cutting style is faceted, using a mixed brilliant cut that balances table size and pavilion facets to maximize light return and to preserve the color change phenomenon, which is the defining property of true alexandrite. Under fluorescent and daylight sources the gem displays a lively greenish tone, while under incandescent light the stone shifts to a distinct reddish hue, and this example shows vivid color intensity in both lighting environments. Clarity has been evaluated at eye level as very slightly included, meaning there are minor inclusions visible under careful viewing at normal distances, yet these inclusions do not impede the gem to display strong transparency and exceptional scintillation. The polish is excellent, with crisp facet junctions and a mirror like finish that enhances both the green and red faces of the gem, and importantly, this alexandrite has received no enhancement, holding its natural integrity and origin documented as Brazil.

From a gemological and collecting perspective, this alexandrite compares favorably to the classic historical alexandrites from the Ural Mountains that first captured the world in the nineteenth century, in that it exhibits a clear and sharp color change, a trait that defines premium alexandrite in the marketplace. While Ural material is famed for its classic bluish green to raspberry red change and historical provenance tied to Russian imperial collections, modern Brazilian deposits have produced stones with equally compelling color change and often with cleaner crystal structure and different body tones that some connoisseurs prefer. In terms of clarity and cutting, this stone benefits from a mixed brilliant cut that is reminiscent of the careful faceting seen in museum quality gems, and the very slightly included clarity grade is a notable advantage over many natural emeralds which commonly require treatments to improve clarity. Compared to high grade rubies and sapphires that command premiums for saturated single tone color, alexandrite occupies a unique niche because its value is driven not only by saturation and clarity, but also by the strength and quality of the color change, the uniformity of tone across lighting conditions, and the rarity of larger specimens showing vivid change, making a 3.60 carat vivid alexandrite truly exceptional.

For educated buyers and collectors, the long term appeal of this gem is founded on several objective factors, all of which are embodied in this particular piece and endorsed by The Natural Gemstone Company. Alexandrite is a variety of chrysoberyl renowned for its hardness of about 8.5 on the Mohs scale, offering outstanding durability for daily wear in rings and other jewelry, while its color change mechanism is the result of specific trace element chemistry interacting with light, a phenomenon that cannot be replicated by simple dyeing or heating, and which in this parcel is natural and untreated. The combination of vivid color intensity, excellent polish, and a clean eye level clarity means the stone will present well both in a bespoke jewelry setting and as part of an investment quality collection. The size and proportions, specifically the 10.78 x 7.82 x 4.65 mm oval, are ideal for center stone settings that allow the color change to be appreciated from multiple angles, and the mixed brilliant cut enhances the gem to show both deep color and lively sparkle. For provenance conscious buyers, Brazilian alexandrite has become increasingly desirable because Brazilian mines have produced fine examples with stable color change and attractive body tones, and because this stone is free from any enhancement, it commands preference among connoisseurs who prioritize natural state and verifiable origin.
