1.78 Ct. Alexandrite from Madagascar

Discover one exceptional gemstone from The Natural Gemstone Company, a transparent 1.78 carat cushion shape alexandrite that measures 8.51 by 6.90 by 3.43 millimeters, a remarkable example of nature at its most enchanting. This stone has been masterfully faceted with a mixed brilliant cut, designed to balance the deep, shifting hues with lively scintillation, and has an excellent polish that allows every facet to return light with a crisp, clean flash. Evaluated at eye level as eye clean, this alexandrite shows no visible inclusions to the unaided eye, preserving the purity of its appearance and enhancing its wearable beauty. With a medium intense color intensity and a breathtaking color change that shifts from yellowish green to reddish green, this gem offers a dynamic presence that few other stones can match, and it is completely natural, with no enhancement. Sourced from Madagascar, a region increasingly known for producing fine alexandrite, this gem carries provenance that collectors and connoisseurs value, and it arrives to you with the integrity and care that define The Natural Gemstone Company.

For those seeking color drama and sophistication, the color change itself is the defining characteristic, and this alexandrite performs beautifully in that regard. In daylight or cool white light the stone reveals a yellowish green persona, fresh and lively, reminiscent of new growth in a sunlit garden. Under incandescent or warmer light the stone shifts toward a reddish green, a softer, more romantic character that seems to come alive as warmth and candlelight play across the facets. That dual personality is not a surface effect or a coating, it is a result of the gem absorbing and reflecting wavelengths of light in a way that few minerals can achieve, an optical phenomenon that commands attention and invites conversation. The medium intense saturation ensures that both color states are distinct and pleasing, avoiding the washed out look of pale examples while remaining wearable for everyday settings. For someone choosing an engagement ring or a signature piece, this alexandrite offers an emotional experience, a daily reminder that subtlety and surprise can coexist in one remarkable jewel.

When comparing brilliance and sparkle to more common gemstones, this alexandrite stands apart for reasons beyond its color change. Diamonds are renowned for exceptional fire and sparkle due to their high refractive index and dispersion, and a well cut diamond will scatter white light into brilliant flashes, which is why they have become the benchmark for brilliance. Sapphires and emeralds often present a rich, saturated face up color but usually lack the same level of scintillation that a mixed brilliant cut can provide. Tourmalines and garnets display their own lively colors, yet they do not possess the dramatic shift in appearance that defines alexandrite. The mixed brilliant cut of this cushion shape alexandrite has been chosen to maximize both color and light return, combining the depth and soft silhouette of a cushion profile with the faceting strategy that enhances scintillation and flash. Because the stone is eye clean, light moves through the crystal with minimal interruption, translating into a lively play of light without the dulling that inclusions can cause. The excellent polish further refines that performance, allowing each facet to reflect and refract cleanly, which intensifies the perceived brightness and makes the color transitions more vivid. In practical terms the result is a gem that captures attention like a fine sapphire when viewed face up, yet reveals the emotional drama of a ruby in warm light, and it accomplishes this while retaining a brilliance that outshines many stones of similar size in everyday settings.

This alexandrite is presented by The Natural Gemstone Company as the perfect solution for customers who have been searching for something that combines rarity, beauty, and wearability. For couples seeking an engagement ring that stands apart from traditional choices, this gem offers a daily surprise, a conversation piece that changes with the light and with the mood. For collectors, the combination of natural origin, no enhancement, and eye clean clarity makes this example a responsible and desirable acquisition, fit for a curated cabinet or a legacy design. Its 1.78 carat weight and balanced cushion proportions make it suitable for a variety of settings, from classic four prong mounts that allow light from all angles, to halo settings that accentuate the color change and increase perceived size. Caring for it is straightforward, gentle cleaning with warm soapy water and a soft brush will maintain its polish, and periodic professional inspections will keep any setting secure. We at The Natural Gemstone Company stand ready to assist with selection, custom design, and certification guidance, because we understand that finding the right gemstone is a personal journey, and we believe that with this alexandrite, your search can end here. If you are drawn to a stone that combines the unusual and the wearable, the lively and the romantic, this Madagascar alexandrite offers a rare opportunity to own a jewel that truly answers the heart.
