10.48 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

There are gems that speak of moonlit shores, of ancient traders and royal treasuries, and this exquisite brown moonstone embodies that long and storied lineage. From the historical mines of Ceylon, Sri Lanka, where gem cutting and appreciation have been refined over centuries, this translucent round moonstone carries the quiet dignity of a gem that was once sought by kings and mystics alike. At 10.48 carats, its presence is substantial without being flamboyant, offering a measured grandeur that suits those who favor pieces with heritage and restraint. As a representative of the natural world and the timeless craft of gem cutting, this moonstone invites you to become part of its ongoing story, a narrative preserved and presented to you by The Natural Gemstone Company.

Examining its physical attributes, you find details that confirm its classic quality and enduring appeal. The stone is round in shape, with dimensions of 12.99 x 12.85 x 9.14 mm, proportions that translate into a comfortable and versatile size for many types of jewellery. It is cabochon cut, a traditional style that highlights the internal glow and adularescence for which moonstones are celebrated, while also offering a smooth, tactile surface that promises a lifetime of wear. Clarity is graded as very slightly included at eye level, an indication that the stone remains clean to the unaided eye, while retaining natural character and authenticity. The color intensity is light, a gentle brown tone that reads as earthy and sophisticated, and the finish is completed with an excellent polish, producing a luminous surface. Importantly, there has been no enhancement, the gem is untouched by treatments, and its origin from Ceylon, Sri Lanka, gives provenance that collectors and connoisseurs appreciate.

For those who cherish classic design and generational value, this moonstone adapts beautifully to settings that emphasize lineage and understatement. Consider a low bezel setting in warm yellow gold, where the brown undertone and soft transillumination will resonate with the metal, evoking antique signet rings or heirloom pendants. A delicate halo of small brilliant cut diamonds can add a whisper of contrast without overshadowing the moonstone, permitting the stone to remain the focal point while introducing a timeless frame. In white metals such as platinum or white gold, the light brown will take on a cooler, almost ethereal mood, ideal for designs that lean toward vintage elegance. For a wearable everyday piece, a cabochon ring with a secure bezel and a smooth profile will protect the stone, while as a pendant the dimensions and weight make it prominent enough to command attention when worn close to the heart. This moonstone is particularly well suited to jewellery that values continuity, such as family gifts, commemorative pieces, or curated additions to a classic collection.

Caring for a gem with such heritage is straightforward, and the practices echo the respect it deserves. Because it is natural and untreated, avoid harsh chemicals and extreme temperature changes, do not use ultrasonic cleaners, and clean with warm soapy water and a soft brush, followed by gentle drying with a soft cloth. Store the moonstone separately from harder stones like diamonds to prevent scratching, and consider a soft pouch or lined box for safe keeping.
