0.37 Ct. Moonstone from Ceylon (Sri Lanka)

If you are seeking a gemstone that transforms a custom piece into a statement of refined taste, this transparent 0.37 carat emerald cut rainbow moonstone from Ceylon Sri Lanka is a solution that resolves your search. Offered by The Natural Gemstone Company, this moonstone presents a rare combination of clarity, polish, and a delicate light color intensity that suits both classic and contemporary commissions. The proportions are precise at 5.09 by 4.22 by 2.69 mm, and the emerald cut emphasizes clean lines and elegant symmetry, inviting jewelers to design with confidence. With a clarity grade of slightly included when evaluated at eye level, the stone retains a natural character that many collectors and bespoke jewelry clients appreciate, while the excellent polish ensures crisp facet edges and lively surface reflection. There is no enhancement to this gem, which means the subtle play of rainbow adularescence you see is wholly natural, and the origin in Sri Lanka is a hallmark of quality sourcing that reassures connoisseurs and sentimental buyers alike.

For custom jewelry designers and clients who know that size and shape determine how a gem will live in a setting, this 0.37 carat emerald cut moonstone offers exceptional versatility. Its compact dimensions are ideal for an elegant solitaire engagement ring intended for someone who prefers a refined, understated center, and the elongated emerald outline also lends itself beautifully to horizontal or east west settings that feel modern and personal. The facet arrangement of an emerald cut creates a step cut effect that showcases the moonstone's inner light, allowing the rainbow flash to appear as a calm, directional shimmer rather than a chaotic sparkle, which makes it perfect for halo designs that amplify size without overpowering the stone. In a pendant, the measured proportions create a poised drop that sits close to the collarbone, and as a pair of matched stones the shape and size are well suited to delicate drop earrings, ear climbers, or bezel set studs that protect the gem while highlighting its color. For those imagining a three stone ring or a custom band with accent diamonds, the stable geometry of the emerald cut gives designers a reliable blueprint for symmetry, channel settings, and gallery work, making the creation process smoother and the finished piece visually cohesive.

Choosing this moonstone from The Natural Gemstone Company means you are selecting a gem ready to be set without alteration, accompanied by the reassurance of ethical sourcing and meticulous selection standards. The slightly included clarity is an honest attribute that confirms natural formation and offers a unique fingerprint, and the excellent polish means the cutter invested time to maximize the gem's optical performance. For clients looking for a protective approach in everyday wear, we recommend settings that shield the table and corners, such as a low bezel or a sophisticated prong design that supports the corners while allowing light to enter the pavilion. If your priority is to showcase the adularescence, a minimal prong setting on a slender band will allow movement to reveal flashes of rainbow color with changing light. Our team can assist with design consultations, matching stones for paired projects, high resolution images and videos, and guidance on metal choice so that warm gold enhances the moonstone warmth while cool white gold or platinum emphasizes the silvery adularescence. When you want a gemstone that ends the search for balance between size, shape, and authentic beauty, this emerald cut 0.37 carat rainbow moonstone is the precise answer, and The Natural Gemstone Company is ready to help you realize the custom piece that turns that answer into an heirloom.
