1.79 Ct. Cabochon Alexandrite from Madagascar

When you are searching for a gemstone that ends a long quest for rarity and beauty, this translucent 1.79 carat oval alexandrite answers that search with confidence. Carefully selected by The Natural Gemstone Company, this stone measures 7.17 by 6.14 by 4.26 millimeters, an impressive size for an alexandrite with such remarkable translucency and presence. The cabochon cut enhances the gem by presenting a broad, even surface that reveals the depth of its color change from greenish to brownish with a smooth, glowing effect. Clarity is very very slightly included when evaluated at eye level, which means the gem reads clean to the viewer while retaining the natural character that collectors value. Intense color intensity and an excellent polish combine to deliver a visual experience that is rare among alexandrites of comparable weight and shape. Best of all, this piece is free of enhancements, and its origin in Madagascar adds a layer of provenance that discerning buyers appreciate. If you are seeking a centerpiece stone for an engagement ring that will draw conversation, or a singular addition to a connoisseur collection, this alexandrite meets both needs with a rare balance of size, color, and natural integrity.

What sets this alexandrite apart in the marketplace is the uncommon pairing of size and color. Alexandrite is prized for its color change, and many available examples that show pleasing tones are either much smaller or have paler transitions. Finding a cabochon of 1.79 carats that consistently presents a greenish hue in one light and a warm brownish tone in another, with intense saturation, is highly unusual. Most alexandrites at this size show less dramatic shifts, or they display muted or mixed tones that lack clarity. This gem, by contrast, offers a vivid and well defined shift, made more striking by the cabochon cut which concentrates and displays the color rather than dispersing it through facets. For collectors who compare alexandrites side by side, this piece will hold its own because of its exceptional color intensity and polished surface. In addition, its translucency allows light to move through the stone in a way that emphasizes the color change without revealing excessive internal features, so the very very slightly included clarity grade actually contributes to the gem story rather than detracts from it. From a rarity standpoint, Madagascar is known for producing fine alexandrite material, but stones with this combination of weight, hue, and cabochon presentation are scarce. When similar stones appear on the market they often have been treated to enhance color, or they are smaller and less impactful. This alexandrite is neither treated nor undersized, which makes it a standout option for buyers who demand authenticity and presence.

Choosing this alexandrite from The Natural Gemstone Company means selecting a stone that resolves the common compromises buyers often face, such as choosing between size and color, or between untreated material and visual appeal. It is ideal for a bespoke engagement ring where the wearer desires a gem with depth and personality, and it is equally perfect as a collector piece that anchors a cabinet of rare color change gems. The cabochon form lends itself to a variety of settings, including bezel mounts that protect the high dome and showcase the color shift, and classic four prong or halo designs that provide a contemporary presentation while preserving the cabochon silhouette. From an investment perspective, the market for natural, unenhanced alexandrites remains tight, particularly for pieces that combine weight and intense color, so this stone is likely to retain or increase its desirability over time. As your gemstone advisor at The Natural Gemstone Company, I can arrange detailed imagery, lighting demonstrations, and consultation on setting options to ensure the final piece fulfills your vision. If your pursuit has been for an alexandrite that is both rare in size and rare in color, this 1.79 carat Madagascar cabochon is the solution that lets you stop searching with confidence.
