1.53 Ct. Alexandrite from Madagascar

This exquisite alexandrite offered by The Natural Gemstone Company is a remarkable choice for a meaningful engagement ring, combining rarity, durability, and visual drama. We present a transparent 1.53 carat cushion shaped alexandrite, with precise dimensions of 6.55 x 5.83 x 4.67 millimeters, cut in a mixed brilliant style to maximize both scintillation and the stone s distinctive color change. Under daylight and cool lighting this stone displays a yellowish green hue, while under incandescent or warmer light it shifts to a reddish brown tone, illustrating the classic alexandrite phenomenon that has fascinated collectors for generations. The gem has been graded as very slightly included at eye level, meaning that inclusions are minimal and do not impact the gem s face up performance in typical viewing, and the polish has been evaluated as excellent, ensuring crisp facet junctions and lively return of light. There has been no enhancement applied to this alexandrite, and its documented origin is Madagascar, a source known for producing some of the most attractive recent finds of color changing corundum and chrysoberyl.

From a gemological perspective this alexandrite is compelling on several fronts that matter to an informed buyer. The material s intense color intensity indicates strong saturation and purity of tone in both lighting conditions, which translates into a stone that reads boldly on the finger without appearing overly dark. The color change effect in alexandrite arises from selective light absorption caused by trace elements within the crystal lattice, producing the unusual ability to present markedly different colors under different spectral conditions. A mixed brilliant cut is an ideal choice for this material because it balances pavilion faceting for light performance with crown facet design that allows the color to present consistently across the table of the gem, rather than pooling into dark zones. The very slightly included clarity grade, determined at eye level, is a practical and desirable clarity tier for colored gemstones, offering a high degree of transparency and brilliance while also reflecting the natural origin and character of the specimen. The excellent polish enhances these attributes, ensuring the stone sits with a crisp, lively face up appearance in candidate ring settings. The Madagascar origin adds provenance value, as recent Madagascar alexandrites have become sought after for their distinct palette and good crystallographic quality.

When considering an engagement ring, this 1.53 carat alexandrite is an exceptional choice both for aesthetic and practical reasons. At the given dimensions it provides a substantial and elegant presence on the hand without becoming cumbersome, making it suitable for daily wear when properly set and maintained. Alexandrite has a hardness of approximately 8.5 on the Mohs scale, which provides strong resistance to scratching, and combined with its toughness it is an excellent gemstone for rings intended to be worn every day. For protection and visual enhancement we recommend settings that balance security and light exposure, such as a four or six prong crown for a classic solitaire, a low bezel for maximum protection, or a halo design to amplify perceived size and to complement the color change with accent diamonds. The choice of metal will influence appearance, with white metals such as platinum or white gold tending to emphasize cooler green aspects of the stone under neutral lighting, and yellow or rose gold introducing a warmer backdrop that can accentuate the reddish brown appearance under incandescent illumination. Because this alexandrite is entirely untreated, its natural origin and integrity command a premium among knowledgeable buyers, collectors, and brides or grooms seeking a one of a kind center stone.

As a trusted source of fine natural gemstones, The Natural Gemstone Company stands behind the quality and provenance of this alexandrite, and we are prepared to provide additional high resolution imaging, videos showing the color change under multiple lighting conditions, and independent laboratory reports upon request from reputable gemological laboratories. We are happy to advise on design options, metal choices, and setting styles that will protect and showcase the gem s color change while ensuring comfortable daily wear.
