6.65 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

If you are searching for a unique center stone for an engagement ring, or a rare, high quality gem to add to a curated collection, this moonstone answers that need with quiet confidence, and grace. This translucent grey moonstone weighs 6.65 carats, and measures 15.74 by 8.55 by 6.72 millimeters, presented in an elegant oval shape with a cabochon cut that enhances its inner glow. Sourced from Ceylon Sri Lanka, the stone shows a light color intensity and a subtle adularescence that will appeal to a buyer who wants something unconventional, yet refined. The clarity is graded as very slightly included when evaluated at eye level, and the polish is excellent, giving the surface a smooth, reflective finish that looks beautiful alone, or set into a bespoke piece.

Imagine this gem as the focal point of a modern engagement design, where its soft grey tones allow creative combinations with warm yellow gold, cool white gold, or contemporary rose gold, depending on the emotional tone you want to express. For collectors, its natural origin and the fact that there is no enhancement make it an attractive acquisition, a genuine example of fine Ceylon moonstone with integrity and provenance. The cabochon cut maximizes the gem’s optical character, offering a gentle, moving sheen that invites touch and contemplation. With dimensions that make it substantial without being oversized, it sits comfortably on most ring profiles, pendants, or custom brooch settings, lending an air of understated luxury.
