0.68 Ct. Moonstone from Madagascar

This white moonstone is a precisely measured example of natural feldspar, weighing 0.68 carat, with oval dimensions of 6.60 x 4.74 x 4.07 millimeter, semi transparent in bodytone and near colorless in hue. The gemstone has been fashioned in a mixed brilliant cut, combining a carefully faceted crown with complementary pavilion geometry to maximize light return and to emphasize adularescent effects. Clarity has been evaluated as slightly included at eye level, which is consistent with natural moonstone habit and which does not substantially detract from visual appeal. The polish is excellent, and the piece has received no enhancement, retaining its natural surface integrity and optical character. The origin is Madagascar, a provenance respected for producing clean, near colorless moonstone material with fine internal layering.

The mixed brilliant faceting on this oval has been executed to balance scintillation and internal sheen, employing smaller crown facets to break light into precise flashes while preserving larger pavilion facets to reinforce the stone structure and to channel the adularescence toward the table. The length to width ratio creates an elegant oval outline that enhances directional light return when set in either a north south orientation or east west orientation, depending on design intent. Proportion analysis indicates a pavilion and overall depth relationship that is moderately deep, approximately seventy two percent when measured against the average of length and width, which increases internal reflection events and strengthens the soft moonstone glow, at the cost of optical spread when compared to shallower cuts. This trade off has been intentionally managed by the cutter to prioritize a pronounced internal sheen and balanced brilliance, resulting in a gem that appears lively under both diffuse natural light and directional artificial light.

Clarity characteristics are typical for feldspar based moonstone, with planar micro layering and fine inclusions that are visible under close inspection but unobtrusive at normal viewing distances, supporting the slightly included grade recorded at eye level. These internal features are not flaws in the conventional sense, they are structural properties that scatter light to produce the classic moonstone adularescence, and in this specimen they contribute to a subtly dynamic play of light across the table and crown facets. The near colorless body allows a neutral backdrop for that adularescent sheen, producing cool white and faint blue flashes without the interference of color zoning. The excellent polish enhances surface light transmission and ensures strong facet demarcation, while the absence of any enhancement means the optical performance and stability of the stone are entirely natural, a key consideration for collectors and connoisseurs who prioritize untreated material.

Owning this moonstone is an investment in both beauty and craftsmanship, because it embodies selective cutting decisions, natural optical phenomena, and untreated provenance from Madagascar. For designers and collectors the value lies in the combination of a disciplined mixed brilliant faceting approach, consistently executed finishing, and the rarity of a clean, near colorless specimen of this weight and proportions. The gem is well suited to bespoke settings that showcase its adularescence, such as low bezel mounts that protect the girdle and preserve light interaction, or open prong designs that allow light to enter the pavilion freely, enhancing internal reflections. As part of a curated collection this moonstone offers long term appeal due to its stability, natural state, and distinctive optical character, and The Natural Gemstone Company stands behind its selection for patrons who seek technically refined, untreated gemstones that resonate with both aesthetic and investment sensibilities.
