0.99 Ct. Alexandrite from Madagascar

Among the handful of truly remarkable stones that pass through our hands each year, this alexandrite stands apart, and The Natural Gemstone Company is pleased to present it as a rare opportunity for the collector who seeks a singular expression of nature and craftsmanship. Weighing 0.99 carat, and measuring 6.45 by 5.31 by 3.65 millimeters, this oval gem carries an intimate presence that is both wearable and collectible, a jewel that reads as classic and discreet, while holding a secret spectacle within its depths. Its color shift from a greenish hue in daylight to a warm orangish tone under incandescent light is the characteristic that makes alexandrite legendary, and this Madagascar origin specimen exhibits that phenomenon with a medium color intensity that is immediately captivating. No enhancement has been applied, and the stone has been left in its untouched natural state to preserve the integrity and provenance of the material. Ownership of a natural alexandrite of this quality is uncommon, and acquiring it places the buyer among a select group who value authenticity, geological story, and the quiet prestige of a gemstone that reveals itself differently with each change of light.

The cut of this gem is a mixed brilliant cut, executed in an oval outline, and the cutting choices here are purposeful, refined, and performance oriented. A mixed brilliant cut combines the fire and scintillation of a faceting scheme based on brilliant geometry on the pavilion, with a more classical step or modified pattern on the crown, and in this piece that combination creates a three dimensional interplay of light that both preserves color and amplifies life. The oval form lengthens the path of light through the body of the stone, allowing the greenish to orangish tones to mingle and emerge depending on source and angle, and the pavilion facets have been balanced to return light toward the table and crown in a controlled, lively manner. Excellent polish ensures that each facet edge rides cleanly through the passage of light, producing crisp flashes and soft glows without stray diffusion, and the careful facet alignment inherent in a well executed mixed brilliant design enhances the gem capacity to display both bright white sparkle and separated spectral flashes, a duality that in alexandrite translates into vibrant color play and apparent depth.

Clarity is described as very slightly included, evaluated at eye level, and that assessment speaks to a clarity character that is reassuringly transparent while retaining the natural signature of the stone. Because of the mixed brilliant cut, inclusions that may be present at a microscopic level are often masked by the complex internal reflections, and instead of interrupting the beauty of the gem, they can provide individuality, subtle fingerprint, and a story of origin. The dimension ratio and depth to table relationship in this oval have been calibrated to support both optical performance and clean face up appearance, which means that at normal viewing distances the gem reads as luminous and almost free of distraction. Medium color intensity here is an advantage, as the gem does not appear overly saturated and therefore allows the color change to be more legible under varying light sources. Under daylight the greenish notes are fresh and botanical, with cool undertones that feel precise and elegant, and under warm light the orangish glow becomes tender and embracing, creating an emotional shift that resonates differently for each wearer and each moment.

From a connoisseurship perspective, the origin and the untreated nature of this alexandrite raise its desirability considerably. Madagascar has become increasingly recognized for producing alexandrite material with interesting color change and clean crystals, and this piece exemplifies those qualities while remaining wholly natural, with no heating or diffusion or other treatments applied. The excellent polish indicates that the cutter took time and intention to finish each facet to a reflective high, and that level of finishing directly translates to performance when mounted. For those who commission bespoke settings, this gem rewards thoughtful design that allows the table and crown to capture ambient light, and settings that incorporate open galleries or prongs that permit light ingress will maximize apparent brilliance and color change. The untreated nature of the stone means that it will patina and age as a natural object of beauty, and because it is rarely possible to find well cut, eye pleasing alexandrite under one carat with no enhancements, this is an acquisition that speaks to refined taste and long term value.

At The Natural Gemstone Company we offer this alexandrite as part of a very limited selection of loose stones, and we handle each enquiry with discretion, personalized consultation, and the option to view the gem in hand by appointment.
