3.15 Ct. Blue Cabochon Sapphire from Ceylon (Sri Lanka)

This listing is for one beautiful translucent 3.15 carat oval shape blue sapphire, with exact dimensions of 9.07 x 7.73 x 4.43 mm, presented in a traditional cabochon cut. The cabochon profile enhances the stone's full color saturation and surface luster, producing a deep, inviting face up that reads as vivid in intensity under a variety of lighting conditions. Clarity has been graded as very slightly included when evaluated at eye level, which means that minor natural inclusions are present but do not detract from the visual impact to the unaided eye. These small inclusions are typical of natural corundum and can include fine silk or tiny mineral crystals, and in this example they contribute to the gemological fingerprint of a natural Ceylon sapphire rather than reducing its desirability. The polish is excellent, producing a smooth reflective dome that maximizes perceived depth and color uniformity, while the overall translucency allows light to travel through the stone enough to reveal nuanced blue tones without appearing opaque.

This sapphire is identified as originating from Ceylon, Sri Lanka, a historical source renowned for producing lively, bright, and often highly collectible blue sapphires. Ceylon provenance is recognized by connoisseurs because the island yields stones with characteristic brightness and evenness of hue, and this specimen exemplifies those traits with a vivid blue that has pleasing saturation and balanced tone. The stone has been heat treated, which is a widely accepted and stable enhancement in the trade, intended to improve color uniformity and clarity without compromising structural integrity when performed under proper conditions. Heat treatment is permanent under normal wear conditions, and full disclosure is provided in keeping with ethical practices. For an educated buyer, the combination of Ceylon origin, disclosed heat treatment, and natural inclusion characteristics often represents the best balance of desirability and value, because it provides the visual qualities associated with premium stones at a more accessible price point than comparable untreated material.

From a practical and investment perspective, this 3.15 carat cabochon sapphire offers several advantages. The carat weight and the oval cabochon dimensions make it well suited to a variety of settings, including bezel set rings, pendants, and signet or men's rings where a low profile and durable mounting are preferred. Sapphire is corundum with a Mohs hardness of 9, second only to diamond, which makes it an excellent choice for everyday wear, and the cabochon cut further reduces the risk of surface chipping by presenting a continuous dome. For a buyer informed about gem grading, the vivid color intensity combined with very slightly included clarity evaluated at eye level and excellent polish translates into strong visual appeal and good marketability. The Natural Sapphire Company stands behind transparent disclosure of origin and treatment, and we can provide additional high resolution images, setting recommendations, and independent gemological reports upon request. Care recommendations include routine cleaning with warm soapy water and a soft brush, avoidance of prolonged exposure to harsh chemicals, and periodic inspection of the mounting to ensure longevity.
