1.20 Ct. Alexandrite from Madagascar

This alexandrite is a beautifully transparent 1.20 carat cushion shape gemstone, showing dimensions of 7.09 by 6.05 by 3.36 millimeters, cut as a mixed brilliant to combine lively scintillation with broad color presentation. The stone exhibits a medium color intensity, with a distinct yellowish green to reddish green color change when viewed under different lighting, and is graded as eye clean at normal viewing distance, meaning no inclusions are visible to the unaided eye. The polish is excellent, which maximizes light return and ensures the surface is smooth and bright, and importantly this gem has no enhancements, being entirely natural in its state. Origin is Madagascar, a recognized modern source for fine chrysoberyl alexandrite, and the proportions work well for both rings and pendants since the depth of 3.36 millimeters on the given length and width yields a balanced profile, approximately 51 percent by depth relative to the average of the length and width, which favors consistent light performance in a cushion form.

For an educated buyer the value of this alexandrite derives from a combination of factors that are easy to verify and appreciate, namely the clarity, color change, cut quality, and natural origin. Alexandrite is a rare color change variety of chrysoberyl, notable for its ability to shift from greenish hues in daylight to reddish hues under incandescent light, a property related to complex absorption in the stone and to pleochroic behavior in some examples, and even with medium intensity this specimen shows a pleasing and noticeable transition that will delight connoisseurs who understand the phenomenon. The mixed brilliant cut has been executed to balance brilliance and color, so the stone returns lively flashes while still preserving the color zones that create the change, and the excellent polish ensures no detracting surface features. Being eye clean increases desirability, because inclusions that are not visible to the naked eye maintain aesthetic purity without the premium reductions associated with visible flaws, and being untreated adds a premium in today’s market where natural, unenhanced stones are increasingly prized by collectors and fine jewelers. Madagascar origins are respected in the trade, offering a modern, verifiable source that many buyers prefer, and the chrysoberyl species itself is durable, with a Mohs hardness of about eight and a half, making this alexandrite well suited to daily wear when set properly.

When imagining this alexandrite in a custom piece the interplay between metal choice, setting style, and accent stones will greatly influence how the color change is perceived and how striking the final piece becomes. For maximum versatility a classic halo setting with small white diamonds will provide high contrast against both the green and the red states, white diamonds amplifying brilliance and making the color appear cleaner and more saturated. If you want to emphasize the green phase, a pairing with vibrant green tsavorite garnets or demantoid garnets will create a lush, monochromatic palette for daylight wear, while pairing with warm pink sapphires or rhodolite garnets will play up the reddish green phase under warmer light, creating a complementary contrast that feels lively and intentional. Metal choice also matters, because a white metal such as platinum or white gold tends to cool and accentuate green tones, while rose gold and yellow gold warm the visual field and will lean into the reddish aspects of the stone, making it feel softer and more vintage. Consider a three stone design with tapered white diamond or pink sapphire shoulders to frame the alexandrite, or an offset design where a small cluster of tsavorites sits at one corner to nod to the green phase, while a pavé band of warm colored melee accents supports the red phase. For daily wear prong settings allow more light to reach the pavilion and encourage stronger color change, whereas a low bezel can protect the cushion shape for active lifestyles while still leaving the table exposed enough to allow the color shift to read well.

From a practical purchasing and design perspective I recommend documenting the gem with a reputable third party report if you prefer additional assurance, and The Natural Gemstone Company is happy to assist with lab grading referrals and with bespoke design services that incorporate CAD sketches and metal and accent choices. For care, routine cleaning with warm soapy water and a soft brush is safe, avoid harsh chemicals and heavy mechanical shocks even though chrysoberyl is quite hard, and periodic professional inspection of prongs and settings will protect your investment. If you are considering a matched pair for earrings or a coordinating pendant we can source compatible accent stones and propose metal and setting options that preserve the color change effect while delivering a coherent design language. Please contact The Natural Gemstone Company to discuss design sketches, metal and accent combinations, or to arrange viewing under multiple light sources so you can appreciate the yellowish green to reddish green transition in person, and we will provide detailed provenance information, condition notes, and personalized recommendations to ensure this 1.20 carat Madagascar cushion alexandrite becomes the centerpiece of a truly exceptional custom piece.
