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

This translucent 2.92 carat oval blue sapphire measures 9.31 by 6.57 by 4.73 millimeters and is presented in a classic cabochon cut, a shape and finish that emphasizes color and surface luster. The gem exhibits a vivid color intensity, with a deep, saturated blue that remains lively across the dome of the cabochon, and an excellent polish that produces a smooth, reflective surface. Clarity has been graded as very slightly included at eye level, meaning the stone is visually appealing and free of any inclusions that distract at normal viewing distances, while internal characteristics consistent with natural corundum are present under closer inspection. Origin is Ceylon, Sri Lanka, a provenance long associated with some of the finest and most collectible blue sapphires in the gem trade. Enhancement has been disclosed as heat treatment, a widely accepted and stable practice used to improve color and clarity without compromising structural integrity when performed to trade standards.

For an educated buyer, the combination of cabochon form, vivid saturation, and Sri Lankan origin is significant. Cabochons are traditionally chosen for stones with exceptional tone or for those that display a pleasing translucency rather than facetable brilliance, and this piece demonstrates exactly that quality, delivering an even, rich color field with soft internal light diffusion. The very slightly included clarity grade, evaluated at eye level, indicates that the stone presents cleanly to the naked eye, and the inclusions that do exist are minor and do not materially affect the gem’s visual appeal or durability. Corundum, the mineral species for sapphire, rates nine on the Mohs hardness scale, which makes this stone suitable for everyday jewelry when properly set. The excellent polish enhances both the apparent depth of color and the gem’s surface condition, a detail that reflects careful cutting and finishing by experienced lapidaries.

Heat treatment is disclosed, and it is important to understand what that means for value and longevity. Heat treatment is the most common and accepted enhancement in trade for sapphires, used to deepen or stabilize color and to reduce the visibility of certain inclusions. When performed correctly, the treatment is permanent and does not require special care beyond normal gemstone maintenance. Ceylon origin further supports the stone’s market appeal, as Sri Lankan sapphires are prized for their clean, bright blues and are often differentiated from stones of other origins by lighter to medium tones combined with strong saturation. Origin can influence collector and market preferences, and many buyers place a premium on well-documented provenance. At a weight just under three carats and with the given dimensions, this oval cabochon offers versatility for bespoke designs, from elegant pendants and statement rings to distinctive men’s jewelry or vintage-inspired pieces where a domed sapphire is desirable. A bezel setting is especially sympathetic to cabochons, protecting the girdle and highlighting the gem’s silhouette, though skilled designers can incorporate this stone into numerous mounting styles.

From an investment and collector perspective, the value drivers here are clear and factual. The sapphire’s vivid color intensity is the primary determinant of aesthetic and monetary value, supported by an attractive size and the positive reputation of Ceylon origin. The very slightly included clarity and the excellent polish mean the gem requires no further treatment to be bridal or exhibition quality, aside from the standard disclosure of heat enhancement. Buyers who appreciate transparency and long-term value will find this combination compelling, as fine, natural Ceylon sapphires with strong color and sound integrity are consistently sought after in the marketplace.
