19.77 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

From the rugged hills of Ceylon, Sri Lanka, where ancient rivers cut through layers of feldspar and the earth folds carry secrets of light, this yellow moonstone began its long journey. Local miners, many guided by knowledge passed down through generations, traced veins of orthoclase and adularia by feel and sight, selecting only the rough nodule pieces that promised a warm, honeyed translucence. The stone weathered slowly in the earth, bathed by monsoon and sun, developing the soft, diffuse glow that moonstone lovers seek. In the villages near the mines artisans and families shared stories about moonstones, calling them gifts of the moon and linking them to calm evenings and hopeful beginnings. At The Natural Gemstone Company we respect that lineage, and we work closely with those who extract and prepare these gems, ensuring that the stone we offer carries not only geological rarity, but also the human stories of its origin.

Careful selection and thoughtful cutting transformed this material into the finished gemstone that you now see. The gem is a single, translucent, 19.77 carat oval yellow moonstone, with dimensions of 23.78 x 11.49 x 9.66 mm. It has been shaped into a classic cabochon cut, a style that honors the nature of moonstone by smoothing the surface into a dome that lets light pass and play within, producing a soft internal glow rather than a sharp sparkle. Evaluated at eye level, the clarity grade is very very slightly included, meaning the inclusions are minute and do not distract from the gem overall beauty. The color intensity is medium light, a gentle, sunlit yellow that is serene and versatile, and the polish is excellent, reflecting a mirror like finish on the dome and a comforting, tactile smoothness when held. This moonstone has received no enhancement, a pure example of natural beauty, and its origin is Ceylon, Sri Lanka, which has a long standing reputation for producing moonstones with character and charm.

The path from raw stone to a ready to set gem speaks to craftsmanship at every stage, and to the way a stone like this can become part of a life. The cutter chose the oval cabochon for its balance and for the way the shape enhances the stone natural translucence, allowing a broad surface to catch ambient light and reveal subtle internal layers. Mounted, this gem would sit gracefully in a ring, pendant, or bespoke piece, the warmth of the yellow moonstone complementing metals such as yellow gold for a sunlit harmony, or soft rose gold for a modern romantic look, and even white metals when contrast is desired. As a salesperson and a student of gemstones, I find that pieces like this speak to those who value quiet luminosity over flash, and who want an honest stone with its story intact. The Natural Gemstone Company is pleased to offer this gem with detailed information about its weight, shape, measurements, clarity, color intensity, cut, polish, enhancement status, and origin, and we are happy to assist with custom design suggestions, secure setting advice, and care recommendations to preserve the stone for generations.

Owning this moonstone is a way to carry a fragment of Sri Lanka landscape and culture into daily life, to hold a gem that was coaxed from the earth by hands that respect tradition and finished by artisans who understand how to reveal inner light. For care, avoid harsh chemicals and sudden temperature shocks, clean gently with mild soap and water, and store separately to maintain that excellent polish. If you are considering this stone for an engagement ring or a signature piece, imagine the way morning light will soften across its surface, or the way evening lamplight will make the color glow. At The Natural Gemstone Company we welcome questions, and we can provide additional photographs, measurements, and guidance to help you envision the final piece. This yellow moonstone is offered as a single 19.77 carat oval cabochon, a natural, unenhanced treasure from Ceylon, Sri Lanka, ready to be set into a design that will become part of your story.
