0.59 Ct. Moonstone from Ceylon (Sri Lanka)

This listing describes a beautiful, transparent 0.59 carat emerald cut white moonstone, with precise measurements of 6.41 x 4.11 x 3.23 mm, originating from Ceylon Sri Lanka, and supplied by The Natural Gemstone Company. The stone is fashioned in an emerald cut, a classic geometric step cut characterized by a broad flat table and parallel facets that emphasize clarity and directional light. The moonstone is colorless in color intensity, and carries a clarity grade of very slightly included, evaluated at eye level. The polish is excellent, and there has been no enhancement applied to alter the stone, which preserves its natural optical properties and contributes to its intrinsic value. These objective attributes together define the gem for an informed buyer, and the exact dimensions and weight provide the practical information needed for design and appraisal.

The emerald cut geometry is a deliberate and functional choice for this moonstone, designed to allow maximum light play while maintaining a clean, architectural aesthetic. Emerald cut stones are cut with long step facets that run parallel to the girdle, forming a sequence of concentric planes that reflect light in broad, linear flashes. For transparent moonstone, which displays adularescence due to the interplay of orthoclase and albite lamellae, the step faceting accentuates the directional shimmer and creates an elegant hall of mirrors effect. The broad table of the emerald cut gives a clear window into the interior of the gem, showcasing the quality of the feldspar layers and the clarity grade. Because the facets are larger and more planar than small brilliant facets, they promote larger, longer reflections and permit a more controlled, dramatic presentation of the moonstone sheen, rather than scattering light in many tiny sparkles. The result is a gemstone that reads clean and sophisticated, yet alive with ethereal internal light.

From a grading and valuation perspective, this specimen offers several attributes an educated buyer will appreciate. Transparency in moonstone at this size is uncommon, and combined with a colorless body tone it allows the adularescent effect to appear pure and uncolored, which is highly regarded. The clarity grade of very slightly included at eye level indicates there are only minimal internal features visible to the unaided eye, preserving visual appeal while remaining realistic about natural inclusion content. Origin from Ceylon Sri Lanka is significant, as Sri Lankan feldspar is known for producing fine, translucent to transparent moonstones with a clean body color and a lively sheen. The absence of enhancements means the gem trades on natural quality alone, which is preferred by collectors and connoisseurs who value authenticity. Excellent polish ensures the facets meet smoothly and reflect consistently, adding to the stones ability to deliver a strong, unified light response. Taken together, these factors make this emerald cut moonstone appealing for high end jewelry applications and for collectors seeking stones with documented natural quality and refined cutting.

For practical considerations, this 6.41 x 4.11 x 3.23 mm emerald cut moonstone is well suited to a variety of settings where the step cut and table orientation can be used to best effect. A bezel or low profile prong setting will protect the girdle and corners while allowing the table to face upward and capture environmental light, maximizing the adularescent display. For rings, a protective setting is advisable because moonstone is a relatively soft gemstone compared with sapphires and diamonds, and secure mounting will reduce the risk of abrasion and chipping. For pendants and earrings, the orientation of the stone can be varied to emphasize linear or central sheen, depending on design intent. The Natural Gemstone Company provides exact measurements and photographic documentation upon request, and can offer further guidance on setting styles and mounting tolerances appropriate for the stones proportions and mechanical characteristics. For buyers concerned with provenance and grading, we supply the factual data needed to compare specimens, and we welcome inquiries for independent lab reports if desired. This emerald cut, colorless, transparent moonstone from Ceylon Sri Lanka represents a refined expression of feldspar geometry and optical phenomenon, ideal for those who value both scientific clarity and aesthetic subtlety.
