21.93 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This extraordinary, opaque black moonstone from Ceylon, presented by The Natural Gemstone Company, is a rare statement gem chosen for collectors and discerning lovers of unique gems, weighing 21.93 carats, measuring 23.16 by 11.75 by 10.37 millimeters, and cut in a classic oval cabochon to showcase its deep, enigmatic surface. The gem is eye clean when evaluated at eye level, unenhanced and fully natural, with a dark color intensity that reads as a refined, velvety black under varied lighting. The cabochon cut and an excellent polish create a luminous, glass like surface that reflects light with a quiet, internal glow, giving the stone both presence and subtlety. Sourced from Sri Lanka, historically prized for producing gemstones of exceptional character, this black moonstone stands apart as an objet d art for bespoke jewellery, limited in number and exceptional in pedigree.

As an engagement option this moonstone offers a compelling alternative for those who seek a meaningfully different and highly personal symbol of commitment, a jewel for someone who embraces depth, mystery, and individuality. Its substantial 21.93 carat weight and generous oval proportions make it ideal for a bold solitaire, a minimal bezel that celebrates the stone itself, or an artisan design that pairs it with discreet accents to preserve its monochrome drama. Because the gem is free from enhancements, the wearer can be assured of its natural origin and enduring character, qualities that translate beautifully into an heirloom engagement piece meant to be treasured for generations. Owning this black moonstone is an invitation to join a select circle of collectors who value rarity and authenticity, and The Natural Gemstone Company stands ready to assist with bespoke setting suggestions, private viewings, and tailored design services to transform this singular gem into an engagement ring that is as exclusive and unforgettable as the love it represents.
