4.03 Ct. Alexandrite from Ceylon (Sri Lanka)

This alexandrite offered by The Natural Gemstone Company is an exceptional and rare example of this legendary color changing gem, it weighs 4.03 carat and measures 10.24 x 7.73 x 6.03 mm, it is masterfully fashioned into an oval shape with a mixed brilliant cut that maximizes fire and color shift, it is transparent with a clarity grade described as very very slightly included evaluated at eye level, the color change runs from a greenish blue in daylight or fluorescent lighting to an orangish red under incandescent light, the color saturation is intense and the polish is excellent, there has been no enhancement and the origin is Ceylon Sri Lanka. Compared to the majority of alexandrites on the market this piece is notable first for its size and second for the purity and intensity of its color change, most alexandrite material in circulation is under one carat and shows only a muted or partial color change, a 4 carat gem that swings dramatically from greenish blue to a warm orangish red is extremely rare and commands attention from collectors and connoisseurs alike. The mixed brilliant cut was chosen to balance table brightness with deep pavilion facets that enhance the chromatic shift, the facet pattern allows the gem to read with a lively greenish blue in cool light and transform to rich orangish red in warm light, this is a more pronounced and desirable phenomenon than the soft or muddy changes often seen in smaller or poorly cut examples.

When comparing this alexandrite to other options available in the market the advantages become clear, many stones offered as alexandrite are either too small to exhibit a dramatic color change or are heavily included which dulls the effect, others have undergone heat or diffusion treatment to improve tone or clarity which can reduce long term value, this Ceylon alexandrite is natural and untreated which preserves both its beauty and investment potential. Russian alexandrite is historically prized for strong color change, yet fine Russian material in sizes over two carats is virtually unobtainable today and carries a premium well beyond that of similarly performing stones from other origins, Sri Lankan alexandrite like this one often exhibits a warm, wearable color palette and in this instance displays an unusually intense transition that rivals the best material from traditional sources, the clean eye level clarity and excellent polish further distinguish it from many commercial pieces which rely on heavy cutting to mask inclusions. For buyers seeking a centerpiece gem for a bespoke engagement ring or a museum quality collector piece this alexandrite delivers a rare convergence of size, clarity, cut and color change, this combination is what elevates it above run of the mill alexandrites and places it in a class sought after by experienced gem buyers.

Value and long term desirability are central to how we present this gem at The Natural Gemstone Company, a large, untreated alexandrite with a vivid greenish blue to orangish red change is not only visually spectacular but also structurally valuable because it is so scarce, inscribed and certified stones may be compared by weight and dimensions, yet few match the performance in color and the transparent clarity that this specimen shows, when stacked against synthetic alexandrite simulants and lesser grade natural stones this gem stands apart because it requires no explanation or enhancement to dazzle, its mixed brilliant cut ensures maximum brilliance and the excellent polish heightens the perception of depth, the slightly included clarity evaluated at eye level means that under normal viewing conditions the stone appears clean to the naked eye, this enhances desirability for wearable jewelry and reduces the need for heavy bezels or hidden settings that are sometimes used to conceal less perfect material. Collectors will appreciate the documented Ceylon origin because Sri Lankan alexandrites have a distinct character that often reads as more pastel green to warm red under different lighting, this particular specimen retains intensity in both color states which is uncommon, for investors the natural untreated status is an asset because treatment history can materially affect resale and appreciation.

Presentation and service are important to ensure this rare alexandrite fulfills its potential once purchased, we at The Natural Gemstone Company are equipped to provide additional close up imagery, lighting comparison photos showing the greenish blue to orangish red transition, and guidance on settings that best showcase an oval mixed brilliant cut, an open prong or low bezel with warm metal choices such as yellow gold or rose gold will emphasize the orangish red shift, while white metals will play up the greenish blue state for a cooler look, because of its 10.24 x 7.73 x 6.03 mm dimensions the stone sits prominently in most ring or pendant designs without appearing oversized, our team can advise on proportions for halo or solitaire mounting to retain the gem as the focal point. Every gem we offer is curated for origin and treatment, and we back this alexandrite with the reputation and service standards of The Natural Gemstone Company, if you are seeking a rare, wearable, and investment worthy alexandrite this 4.03 carat oval is a superior option when compared to the small, treated, or poorly performing alternatives commonly available, please contact us for viewing options, certification details, and custom setting recommendations tailored to maximize the color change and visual impact of this extraordinary gem.
