73.71 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This exceptional opaque 73.71 carat oval black moonstone measures 32.73 x 26.50 x 11.60 mm, with a classic cabochon cut chosen to maximize its intrinsic optical charm, clarity, and surface luster. Graded eye clean when evaluated at eye level, this stone shows no visible inclusions that would distract from its rich, dark body color and subtle internal sheen, qualities that are highly prized by informed collectors and connoisseurs. The polish is excellent, delivering a smooth, reflective surface that enhances light movement across the gem, and the piece is completely untreated, no enhancement, preserving its natural character and provenance. Originating from Ceylon Sri Lanka, a locality renowned for producing fine feldspar specimens, this moonstone carries both geographic pedigree and gemological integrity, attributes that add measurable value for educated buyers.

For an engagement ring this stone offers a compelling alternative to traditional choices, combining substantial presence with a quietly sophisticated aesthetic. At 73.71 carats, the weight and dimensions allow for a bold yet elegant setting that makes a statement while remaining versatile in design, from bezel settings that emphasize durability, to halo or mixed metal designs that elevate the cabochon silhouette. Moonstone is a feldspar mineral with moderate hardness, and thoughtful mounting will ensure longevity for everyday wear, making it a practical option for couples seeking a meaningful and wearable center stone.
