3.01 Ct. Cabochon Moonstone from Madagascar

This translucent round blue flash moonstone weighs 3.01 carats, and measures 8.91 by 8.85 by 5.50 millimeters, presented in a classic cabochon cut that optimizes the characteristic adularescence of orthoclase feldspar. The stone exhibits a medium light body color that allows the internal blue sheen to float across the surface when illuminated, and the excellent polish enhances the silky luster that collectors and designers prize. Clarity is graded very slightly included at eye level, indicating minor internal features that do not detract from overall visual appeal but do confirm natural origin to an informed buyer. No enhancements have been applied to this material, and the gem is sourced from Madagascar, a locality known for producing high quality moonstones with attractive blue flashes, making provenance a meaningful part of its valuation. The cabochon dome and dimensions produce a depth ratio that is approximately sixty two percent, a proportion that balances visual presence on the finger or in a pendant, while preserving the internal layering that creates the floating blue light effect.

For an educated purchaser, the value proposition of this piece rests on several objective factors. The weight of just over three carats is substantial for a blue flash moonstone, and because moonstone is primarily evaluated on the strength and uniformity of adularescence rather than traditional color saturation, a clear, well centered blue sheen is a principal determinant of desirability. The medium light body color serves as an effective backdrop for the blue flash, improving contrast without overwhelming translucency. The very slightly included clarity grade, assessed at eye level, indicates natural growth textures and small inclusions that are consistent with untreated Madagascar material, and these features corroborate authenticity rather than detract from it. The excellent polish minimizes surface blemishes, which is important because light reflection across a smooth dome intensifies adularescence. Because there has been no enhancement, the stone carries the additional market premium associated with natural, untreated gems, especially from a reputable source such as The Natural Gemstone Company, which documents origin and treatment status for transparency with discerning clients.

When planning a custom setting, consider combinations that will both protect the cabochon and showcase its blue flash. A low bezel setting in white gold or platinum offers secure protection for the domed outline while allowing the surface to present unimpeded adularescence, and a thin halo of small, colorless melee diamonds will introduce scintillation that contrasts elegantly with the moonstone silk, creating a modern yet classic statement. For richer color harmony, pair the moonstone with cornflower blue sapphires or pale aquamarines set as accent stones, these cool toned gems will echo the blue flash and amplify the visual theme without competing with the moonstone center. For warm metal choices, a rose gold bezel provides a pleasing contrast, the subtle warmth around the cool blue center yields a refined, contemporary look suited to cocktail rings or pendant pieces. In a more artisanal direction, consider combining this cabochon with small moonstone melee set alongside moonstone slices or with silver granulation for a bohemian aesthetic, while still preserving light access to the dome so the adularescence remains the focal point.

For practical considerations and long term enjoyment, recognize moonstone has a Mohs hardness around six to six and a half, and the cabochon profile makes it ideal for settings that reduce exposure to knocks. Bezel settings and protective gallery work are recommended for rings intended for regular wear. Cleaning should be gentle, using warm soapy water and a soft brush, and avoid ultrasonic or steam cleaning to preserve the structural layers responsible for adularescence. When commissioning a custom piece, share the exact measurements 8.91 by 8.85 by 5.50 millimeters and the 3.01 carat weight with your jeweler, along with the information that the stone is untreated and originates from Madagascar, so the setting can be designed to enhance the blue flash while safeguarding natural characteristics.
