2.08 Ct. Cabochon Moonstone from Madagascar

This listing presents one beautiful translucent 2.08 carat round blue flash moonstone, expertly cabochon cut, with dimensions of 9.17 by 9.30 by 3.28 millimeters, a clarity grade of very slightly included evaluated at eye level, medium light color intensity, and an excellent polish. The stone displays a pure blue adularescence that appears as a striking flash across the dome, balanced by a clean translucent body that allows light to interact with the internal lamellar structure. No enhancement has been applied, and the gem is of Madagascar origin, a source known for producing moonstones with especially clean, cool blue flashes. The piece is presented by The Natural Gemstone Company, and it is offered as a natural, untreated example that will appeal to collectors and designers who prioritize provenance and optical performance.

From a gemological perspective, this moonstone is notable for the combination of size, translucency, and blue adularescence. Moonstone is a potassium feldspar with alternating microscopic layers that scatter light to create the ethereal sheen known as adularescence, and in this specimen the effect is well defined because of the excellent polish and minimal internal disruption. The very slightly included clarity grade means that inclusions are present but are not intrusive at normal viewing distance, allowing the blue flash to remain the dominant visual feature. Many blue flash moonstones at this price point and size exhibit either heavier clouding, smaller dimensions under eight millimeters, or weaker adularescence. A 2.08 carat round cabochon with this level of translucency and a medium light yet vivid blue flash is therefore uncommon, making this stone rarer than the majority of comparable moonstones on the market.

For the educated buyer, this moonstone represents an attractive balance of aesthetic rarity and technical quality. The natural, untreated origin from Madagascar enhances its collectible value, and the round cabochon format makes it versatile for bespoke jewelry settings that preserve the dome and maximize the adularescence, such as bezel settings or soft prong mounts. Care is straightforward, avoid ultrasonic cleaners and harsh chemicals, clean gently with mild soap and warm water, and store separately to protect the polished dome. As offered by The Natural Gemstone Company, this moonstone is a rare combination of size, color, and clarity that will serve well as a focal gem in a fine jewelry commission or as a highlight in a curated mineral collection.
