1.42 Ct. Moonstone from Madagascar

This is a beautiful semi transparent rainbow moonstone weighing 1.42 carats, a classic oval shape measuring 8.28 x 6.34 x 5.37 millimeters, finished in a mixed brilliant cut that maximizes both sparkle and the characteristic adularescence that defines fine moonstone. The gem is graded very slightly included at eye level, a clarity grade that reflects minimal internal features that do not interfere with the gem facing or the optical phenomenon of the stone. The bodycolor is medium light, a tonal range that complements the blue to silvery flash without competing with it, and the polish is excellent, ensuring a smooth, reflective surface that enhances wearability and longevity. There has been no enhancement applied to this stone, and its origin is Madagascar, a provenance renowned among connoisseurs for producing feldspar specimens with superior adularescence and clean crystal structure. The Natural Gemstone Company offers this piece with full disclosure of its measurements, grading, and origin, because transparency and provenance matter to discerning buyers.

To an educated buyer, each of these attributes conveys measurable value. The 1.42 carat weight combined with the oval outline and the dimensions given create a visually appealing table size that sits well in ring, pendant, or bespoke settings, offering a balanced presence without overwhelming most designs. The mixed brilliant cut is intentionally chosen to combine the light performance of brilliant faceting on the crown with controlled pavilion faceting, which stabilizes the stone and focuses the adularescent sheen into broad, mobile flashes. Clarity graded as very slightly included at eye level means that inclusions are minimal under normal viewing conditions, so the gem reads clean to the naked eye while retaining natural internal character when examined with magnification. The medium light color intensity is prized in moonstone because it allows the adularescence to be visible across the gem surface, without a heavy body color that would mute the optical effect. The excellent polish further increases the intensity and sharpness of the flash, improving perceived brightness and jewel quality. The lack of any enhancement amplifies the value proposition, since untreated moonstones, especially with a clear provenance such as Madagascar, are rarer and therefore more desirable for collectors and designers focused on natural materials.

Madagascar has a long standing reputation among gemologists and lapidaries for producing feldspar group gems with exceptional optical phenomena, and this moonstone fits that tradition. The geological environment in Madagascar produces well formed, relatively inclusion free crystals that can be cut to optimize adularescence, and historical trade routes have brought Madagascarn moonstone to markets in Asia and Europe for centuries. That provenance is meaningful for buyers who understand that origin influences crystal habit, typical inclusion patterns, and the strength of optical effects. For the practical jeweler or collector, this means predictable behavior when set into jewelry, consistent polishability, and a reliable aesthetic signature that aligns with other Madagascar sourced stones. The Natural Gemstone Company sources responsibly, and we document origin when it contributes materially to the gem story, because provenance is an important element of value for informed purchasers.

Moonstone carries a rich cultural heritage that enhances its appeal beyond pure gemological metrics, and this piece is part of that living tradition. Historically, moonstone was associated with lunar deities and thought to contain captured moonlight, a belief present in Roman, Greek, and South Asian lore. In India moonstone has long been used as a talisman to attract love and to bring calm to the wearer, and in Art Nouveau and Victorian era jewelry the stone was favored for its soft glow and symbolic connection to the night and to femininity. Contemporary designers and collectors continue to prize moonstone for these associations, using it in bridal jewelry to symbolize new beginnings, in meditation beads to support intuition, and in bespoke pieces that reference historical motifs. For the educated buyer, this cultural and historical lineage is part of the value equation, because provenance, cut quality, and the intangible story of a gem each contribute to desirability and market resilience.

This rainbow moonstone is well suited as a center stone for an understated yet elegant ring, as a focal point in a pendant that allows light to enhance the adularescence, or as part of a curated collection of natural, untreated gems. Care recommendations are straightforward, avoid ultrasonic cleaners and harsh chemicals, clean gently with mild soap and water and a soft cloth, and store separately to prevent abrasion from harder gems. If you would like documentation or to discuss mounting options, The Natural Gemstone Company can provide additional information on setting styles that protect cabochons and faceted moonstone, and we can advise on metals and designs that complement the medium light body color and the blue silvery flash. This moonstone represents a balance of aesthetic appeal, solid gemological grading, and meaningful provenance, attributes that an informed buyer will recognize as markers of enduring value.
