18.57 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent 18.57 carat oval shape brown moonstone, with dimensions 17.41 x 12.43 x 11.50 mm, presents a warm, even tone and a smooth, classic cabochon cut that highlights its silky surface and internal glow. The stone is graded very slightly included when evaluated at eye level, offering excellent visual clarity for its size, and it displays intense color intensity with an excellent polish that catches light evenly across the dome. This moonstone has no enhancement, and its natural origin is Ceylon Sri Lanka, a source known for producing high quality feldspar gems. The weight and size make this piece substantial and versatile, ideal for designers and collectors who value natural, untreated material, and the cabochon shape lends itself to settings that show off the stone body and subtle internal light play.

At The Natural Gemstone Company we present this moonstone as a refined choice for bespoke jewelry and museum quality collections, because its combination of size, color saturation, and untouched origin creates a rare balance of presence and purity. Consider this gem for a statement ring set in a warm metal that complements the brown tones, or a pendant where the cabochon profile can be admired from multiple angles, and for designers who work with mixed materials this stone pairs beautifully with both yellow gold and rose gold, as well as with subtle accent diamonds or colored gemstones. For clients seeking a showpiece that retains its natural character, this moonstone requires minimal maintenance, it benefits from occasional gentle cleaning and careful storage, and since it is unenhanced, its beauty will endure as a true expression of its Ceylon heritage.
