7.34 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing describes one beautiful translucent 7.34 carat round brown moonstone, with measurements of 12.42 x 12.06 x 7.41 mm, cabochon cut, and an excellent polish. The stone exhibits a medium light color intensity, presenting a warm, soft brown tone that reads as elegant and subtle under a range of lighting conditions. Clarity has been graded as very slightly included evaluated at eye level, indicating that the gem has minor internal features that are not intrusive to the overall appearance or to the visual adularescence that moonstone collectors appreciate. There has been no enhancement of this material, and the piece is a natural, untreated example from Ceylon Sri Lanka, a region renowned for yielding moonstones with refined optical effects and clean crystal habits. The round shape and symmetrical cabochon profile maximize the surface sheen, allowing for pleasing movement of light across the dome when the gem is tilted.

From a gemological perspective, moonstone is a member of the feldspar group, and the characteristic sheen known as adularescence is caused by the interaction of light with fine alternating layers within the crystal structure. Sri Lankan moonstones often display particularly soothing and well defined adularescence, and the cabochon cut is the traditional and most effective shape to reveal this property. A clarity grade of very slightly included evaluated at eye level means that when examined with the unaided eye the inclusions are minimal and do not detract from the gem clarity or its translucent quality. Under standard magnification small inclusions or growth features might be more apparent, yet they remain typical of naturally occurring moonstone and can even add to the gemological individuality of the piece. The excellent polish speaks to careful lapidary work, ensuring that the dome is smooth and reflective, which contributes both to visual appeal and to how easily the gem can be set in quality jewelry.

For the informed buyer this moonstone combines desirable attributes that support both aesthetic pleasure and long term value. The weight of 7.34 carats and the near 12.4 mm diameter make this a substantial example suitable as a central stone in a pendant or a statement ring, where the cabochon profile will sit comfortably and present well. The untreated status is an important factor, because many collectors and connoisseurs place a premium on natural, unenhanced gems, especially when the piece retains pleasing color, clarity, and polish without modification. Origin from Ceylon Sri Lanka adds provenance value, since trade history and documented sources matter to those seeking well proven material. In practical terms moonstone has a Mohs hardness of approximately 6 to 6.5, so protective settings such as bezel or halo mounts are recommended for rings intended for frequent wear, while pendants and earrings can take fuller advantage of the rounded form. Avoid ultrasonic cleaners and harsh household chemicals, and clean gently with warm soapy water and a soft brush to preserve polish and surface integrity.
