18.72 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This delightful peach moonstone from Ceylon Sri Lanka is a rare and elegant example of a warm toned, semi translucent gem, weighing 18.72 carats, and shaped into an oval that measures 19.98 by 15.78 by 7.72 millimeters. The cabochon cut enhances the soft, soothing glow that peach moonstones are prized for, and the stone displays a very light color intensity that reads as delicate peach and cream under natural light. The overall appearance is calm and versatile, making it a superb choice for a statement pendant, a refined cocktail ring, or a unique pair of designer earrings. At The Natural Gemstone Company we present this gem with careful photography and honest description, so you know exactly what to expect when composing your finished piece.

In terms of clarity and finish, this moonstone is graded as very slightly included when evaluated at eye level, which means small inclusions are present but do not detract from the gem when set and viewed in typical jewelry use. The polish is excellent, giving the cabochon a smooth, lustrous surface that catches highlights and soft shimmer in movement. There are no enhancements, the stone is untreated, and its natural qualities have been preserved from the mine through to your bench. Origin plays a role in the character of moonstones, and Ceylon Sri Lanka material is known for its pleasing pastel tones and fine internal structure, qualities that contribute to the subtle chatoyance or adularescence that you may observe when light glides across the dome.

When designing with this oval cabochon, consider settings that embrace the stone and allow light to interact with the domed surface. A low bezel will protect the perimeter while a slightly raised bezel can showcase the dome, allowing full visibility of the internal glow. Prong settings with a secure gallery can lift the gem and enable backlighting when desired, which can enhance the apparent depth of color and translucency. Because of its generous dimensions and weight, this moonstone will sit beautifully as a central focal point, especially in pieces that favor organic, soft metalwork or filigree that complements the gentle tone. Its semi translucent nature means that metal choice will influence the perceived color, so warm metals such as rose gold will emphasize the peach warmth, while soft yellow gold will create a vintage inspired warmth, and a neutral white metal will keep the presentation light and modern.

To care for and preserve this moonstone, avoid harsh chemicals, prolonged exposure to sunlight that could fade delicate tones over many years, and rapid temperature changes that can stress the internal structure. Clean gently with a soft cloth and warm soapy water, rinse well, and dry with care. Ultrasonic cleaners and steam should be avoided for moonstones with internal inclusions, and it is best to consult with your jeweler when setting the cabochon to ensure a secure mount that protects the dome from knocks.
