5.09 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

Moonstone has been cherished through the ages for its ethereal glow and lunar associations, and this 5.09 carat oval blue flash moonstone carries that heritage with every gentle turn. Mined in the storied hills of Ceylon Sri Lanka, this stone is an authentic piece of geological history, expertly shaped into a classic cabochon to reveal its signature adularescence. Measuring 11.04 x 9.46 x 6.25 millimeters, the stone presents a soft, opaque body tone with a delicate light color intensity that allows the blue flash to float across the dome like moonlight on calm water. The clarity is graded very slightly included at eye level, a mark of natural character rather than alteration, and the finish is an excellent polish that enhances the stone’s serene surface. No enhancements have been applied, so what you see is the natural beauty of a fine Ceylon moonstone, prepared to be cherished for generations.

The timeless silhouette and subtle luminosity of this moonstone make it infinitely versatile, equally suited to everyday wear and formal occasions. Set in a simple bezel for casual elegance, it harmonizes with denim and linen, bringing a whisper of sophistication to daytime looks. Paired with a refined platinum or yellow gold mounting for evening, the blue flash becomes a focal point, reflecting candlelight and complementing tailored silhouettes. Its oval cabochon form lends itself to classic ring designs, statement pendants, and delicate earrings, and because the gem is unenhanced and exhibits excellent polish, each setting will showcase its natural depth and movement. At The Natural Gemstone Company we present this moonstone not only as an item of adornment, but as a piece of legacy, an heirloom in the making that connects contemporary style with ancient reverence. Whether you seek an understated token of elegance or a centerpiece for a refined jewelry design, this Ceylon blue flash moonstone offers enduring charm and a quiet, lunar luminosity that transcends trends.
