10.52 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

As a gemstone specialist at The Natural Gemstone Company I am pleased to present a single, beautiful translucent 10.52 carat oval yellow moonstone, a gem that stands out for its natural purity and classic cabochon presentation. This piece measures 16.17 by 13.44 by 6.65 millimeters, and its oval shape is a timeless choice for fine jewelry. Evaluated at eye level it carries a clarity grade described as very very slightly included, which means you enjoy a largely clean appearance with only the most minor internal features visible under close inspection. The color intensity is faint and delicate, giving the stone a soft warm glow rather than an overt yellow saturation, and the excellent polish enhances surface smoothness and the gentle light play typical of moonstone. Importantly this gem is untreated, no enhancement, and originates from Ceylon Sri Lanka, a provenance known among connoisseurs for producing high quality feldspar specimens.

When compared to other moonstones on the market this Ceylon yellow moonstone offers distinct advantages in both quality and integrity. Many yellow moonstones available online are heat treated to intensify color, or they are assembled with adhesives or doublets that reduce longevity and resale value. Some sellers offer pieces that are heavily included or cloudy, which diminishes the ethereal glow that collectors seek. By contrast this cabochon is natural and untreated, preserving its original tonal subtleties and structural stability. The translucency of this stone allows light to diffuse gently through the body, producing a serene internal luminescence that is more refined than the harshly colored or overly opaque specimens often marketed as premium. The oval cabochon cut itself is superior for maximizing this effect, because the smooth domed surface and balanced proportions at 16 by 13 millimeters allow a pleasing play of light across the surface, which faceted cuts cannot replicate for moonstone.

Value is another area where this gem excels relative to alternatives. At 10.52 carats it carries significant presence without moving into the rarified price tiers of exceptional rare color varieties, making it an excellent option for a distinctive central stone in custom jewelry. Compared to smaller stones that require pairing to achieve visual impact this single substantial cabochon avoids the complexity and additional cost of matching paired stones. When set in a well designed piece it will offer equity that tends to hold better than treated or composite stones. In addition the Sri Lankan origin adds market desirability because Ceylon moonstones are recognized for their balanced tone and clean material. For buyers seeking natural gemstones with transparent treatment history this moonstone represents honest value, and at The Natural Gemstone Company we emphasize traceable origins and truthful grading so buyers can invest with confidence.

From a design and wearability perspective this stone is versatile and suited to a range of settings, and it presents advantages over many mass market alternatives. The faint yellow hue harmonizes beautifully with warm metals such as yellow gold and rose gold while contrasting softly against white metals for a modern look. Because it is a cabochon, it is ideal for bezel settings that protect the girdle and edges, a recommended mounting approach for moonstone which has moderate hardness. It is also an excellent choice for statement pendants or the central piece of a cocktail ring where the 16 by 13 millimeter face will command attention without appearing bulky. Compared with molded glass simulants that can look too glossy or synthetic, this natural moonstone has a subtle depth and tactile warmth that only genuine mineral specimens provide. The excellent polish on this cabochon ensures that reflections are clean and smooth, and the minimal inclusions help the surface radiance remain undisturbed under everyday lighting.

Practical considerations and care are important for any moonstone owner and this gem compares favorably when handled properly. Moonstone rates about 6 to 6.5 on the Mohs hardness scale, so it is softer than sapphire and topaz but harder than many organics. That means it will wear well in protected settings, and it will maintain its polish and surface integrity with normal care. Avoiding sharp blows to the stone and limiting exposure to harsh chemicals will preserve its appearance, and professional cleaning or gentle soap and water will keep the cabochon looking its best. Compared to softer or treated materials that can suffer color fading or delamination, this solid natural moonstone retains its character over time when cared for. At The Natural Gemstone Company we provide guidance on mounting and maintenance and we are available to advise on bezel thickness and protective design elements to ensure your investment remains beautiful through regular wear.

If provenance authenticity treatment history and superior material qualities matter to you this 10.52 carat Ceylon yellow moonstone is a compelling choice. It combines the desirable physical dimensions and cabochon shaping that maximize moonstone aesthetics, with the reassurance of no enhancement and a clarity that reads very very slightly included at eye level. Compared to treated stones composite pieces or heavily included specimens this gem offers a balance of natural beauty longevity and value that will appeal to collectors and jewelers alike.
