1.70 Ct. Moonstone from Madagascar

This white moonstone from Madagascar brings together rarity and refined cutting in a way few moonstones on the market can match, a transparent oval weighing 1.70 carat, measuring 8.33 by 6.67 by 5.26 millimeters, set in a mixed brilliant cut that maximizes both internal light return and the soft, silvery sheen moonstone lovers prize. At eye level this gem grades as very slightly included, a clarity that allows clean transparency for light to play through the stone while retaining a natural, authentic character that lab grown or heavily treated alternatives simply cannot replicate. The near colorless body color is especially valuable because it provides exceptional versatility for modern jewelry, allowing the adularescence to read pure and clean rather than muddied by a stronger body tone. The excellent polish ensures every facet carries bright, crisp reflections, and the fact that this stone is entirely natural and untreated adds to its desirability and rarity on a market where many moonstones are modified to improve appearance. At The Natural Gemstone Company we place these practical details front and center because knowledge empowers choice, and this moonstone stands apart as a transparent, faceted example that blends classic moonstone charm with contemporary brilliance.

The origin of this moonstone in Madagascar significantly raises its profile and intrinsic value, because Madagascar has become renowned for producing moonstones that combine fine clarity with strong, well defined adularescence. Geological conditions there create crystal growth environments that favor fewer inclusions and cleaner body colors when compared to many sources that yield more common, heavily included material. While Sri Lanka and India remain famous for historic blue and rainbow sheen stones traditionally cut as cabochons, Madagascar has recently supplied gem cutters and collectors seeking facetable, near colorless material with translucence bordering on true transparency. This provenance matters to collectors and designers because origin correlates with a predictability of optical performance, and because responsibly sourced Madagascar gems often come from small scale operations where the story of the mineral, the mine, and the cutter can be traced with greater clarity. At The Natural Gemstone Company we document origin and provide background on sourcing no less carefully than we evaluate cut and clarity, because a moonstone from Madagascar brings not just physical beauty, but a provenance that supports both aesthetic appeal and long term desirability.

Compared to other moonstones offered across the market this specimen offers several concrete advantages in quality, value, and uniqueness. Many moonstones are presented as translucent cabochons to hide plate like inclusions or to emphasize a single, soft sheen, and while those have their place, they do not deliver the same lively interplay of facet brilliance and adularescent shimmer that a mixed brilliant cut produces. The mixed brilliant approach here yields superior light performance while preserving the moonstone character, creating a jewel that photographs well, sparkles in movement, and still gives that ghostly, floating sheen unique to moonstone. In addition this stone is untreated, contrasting with stones that are routinely heat treated, fracture filled, or even assembled from multiple pieces to improve eye appeal. From a value perspective, buyers often compare moonstone to other near colorless choices such as white sapphire or colorless topaz, and this Madagascar moonstone presents a unique alternative that offers warmth, personality, and a softer, more ethereal look, at a price point that can be more attractive than higher graded alternatives in other gem species. When you factor in the clean transparency, the very slightly included clarity at eye level, the excellent polish, and the natural origin, this moonstone represents a superior balance of rarity and wearable beauty.

For designers and private buyers seeking a focal gem for a ring, pendant, or bespoke piece this Moonstone is exceptionally well suited, offering a size and shape that adapts easily to both classic and modern settings, and a hardness and toughness that, with normal care, will wear beautifully when set with protective design choices. Its near colorless face and transparent clarity make it ideal for a halo or solitaire style, and the oval outline reads larger than the weight might suggest once mounted. At The Natural Gemstone Company we support each purchase with full disclosure about the gem, and we are happy to provide additional photos, mounting recommendations, and guidance on care to ensure longevity. Unlike mass produced alternatives, this piece arrives as a single, identifiable gemstone, not a batch item, which appeals to collectors who value individuality and traceable origin. If you are seeking a moonstone that elevates a jewelry design while offering the assurance of natural, untreated material from a reputable Madagascar source, this 1.70 carat transparent oval is a compelling choice, and we invite you to contact The Natural Gemstone Company to discuss how this gem can be incorporated into your next treasured piece.
