11.29 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing from The Natural Gemstone Company describes one translucent brown moonstone, oval shape, weighing 11.29 carats, with exact dimensions 17.79 millimeters by 11.51 millimeters by 8.17 millimeters. The length to width ratio is approximately 1.55 to 1, and the pavilion depth relative to length is approximately 45.9 percent, proportions that yield a balanced elongated oval profile ideal for both ring and pendant designs. The stone is cut as a high domed cabochon, exhibiting an even symmetrical dome and a well centered apex, with an excellent polish that produces consistent specular highlights across the surface. Clarity is graded very slightly included at eye level, indicating minor internal features that do not disrupt the overall translucency or surface luster. Color intensity is classified as intense for this brown tone, uniform across the body of the stone, and the specimen is unenhanced, preserving original material properties and long term stability. Origin is Ceylon Sri Lanka, a source noted for feldspar specimens with fine body color and clean material.

From a lapidary and gemological perspective this moonstone demonstrates refined craftsmanship. The cabochon profile has been shaped to maximize the interaction of light with the internal structure, producing the soft diffuse sheen associated with moonstone adularescence when viewed in motion. The even dome height and well executed transition to the girdle area minimize light leakage and enhance perceived color saturation when set, while the excellent polish minimizes surface abrasions that can obscure subtle optical effects. Minor inclusions are internal, low contrast, and positioned so as not to compromise durability or setting security. Because there has been no enhancement, standard jewelry fabrication practices apply, and the stone will respond predictably to protective settings, particularly bezels and low profile mounts that preserve the cabochon dome. For specification sensitive projects, the precise measurements and proportion data provided here support CAD fitting and prong or bezel planning, and the combination of intense body color, translucency, and superior polish makes this 11.29 carat oval an attractive technical choice for discerning designers and collectors.
