1.24 Ct. Green Grandidierite from Madagascar

This exquisite transparent green grandidierite weighs 1.24 carat, and is fashioned in a classic cushion shape with dimensions of 7.26 by 5.64 by 3.99 millimeters, making it a generous and visually striking gem for a feature piece. The cutting style is faceted with a mixed brilliant cut, and the stone displays an intense color intensity that draws immediate attention. Clarity has been graded as included at eye level, which means that while internal characteristics are present and visible under direct inspection, they sit within a gem that remains transparent and lively. The polish of the stone is excellent, allowing light to enter, refract, and return with the lively flashes and subtle scintillation that are desirable in a high quality colored gem. This specimen is untreated, with no enhancement, and originates from Madagascar, a source renowned for producing fine grandidierite specimens. At The Natural Gemstone Company we present this gem as a rare opportunity for collectors and designers who prize natural color, thoughtful cutting, and verifiable provenance.

For an educated buyer seeking both beauty and technical quality, it is important to understand what the grading details mean for performance and value. The mixed brilliant cut used on this cushion shape optimizes both scintillation and face up color. The crown and pavilion facet arrangement provides a balance between lively flashes and broad color windows, which helps the intense green to read strongly even when the gem is viewed on the finger or in a pendant. Included clarity evaluated at eye level indicates that inclusions are visible without magnification, yet the inclusions in transparent grandidierite often do not compromise structural integrity, and can add to the stone character for collectors who appreciate natural origin. The excellent polish enhances the gem presence, minimizing surface features that could soften the visual impact. Because the gem has not been subjected to heat or other enhancement methods, its intense color reflects natural trace element chemistry and the original geological environment, factors that educated buyers value highly.

Origin and material properties further underscore why this stone is ideal for a statement piece. Madagascar is recognized among connoisseurs for yielding some of the most vividly colored and well crystallized grandidierite specimens, adding a layer of desirability and narrative to the gem. Grandidierite exhibits notable pleochroism, so the apparent hue can shift under different viewing angles, creating a dynamic presentation as the wearer moves. When set with the pavilion and table oriented to favor the strongest color plane, the gem will present its green tone with exceptional depth, taking full advantage of the mixed brilliant cutting strategy. The dimensions and carat weight in this example are particularly suitable for a bold solitaire ring, an elegant pendant, or a center stone surrounded by a halo of complementary diamonds or colored stones to amplify presence. While grandidierite has moderate hardness and requires attentive care, its size and clarity make it practical for wearable statement jewelry when set thoughtfully to protect the girdle and long axis.

From a conservation and care standpoint, the untreated nature and visible inclusions suggest a conservative approach to cleaning and maintenance, which also resonates with discerning buyers who prefer longevity and preservation. We recommend routine gentle cleaning using warm water, mild soap, and a soft brush, avoiding harsh chemicals and forceful ultrasonic methods that may stress internal features. For setting, open prong or bezel styles that allow light to travel through the stone will showcase the intense color and mixed brilliant cut to best advantage, while protective mounting options can reduce the risk of damage during daily wear. At The Natural Gemstone Company we can provide detailed images, viewing angles, and documentation of origin on request, so you may evaluate the stone fully before finalizing a purchase. For an educated buyer seeking a combination of rarity, natural saturation, excellent polish, and a substantial face up footprint, this 1.24 carat cushion green grandidierite represents a compelling choice for a signature statement piece.
