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

One beautiful translucent 3.87 carat oval blue sapphire is offered by The Natural Sapphire Company, presented with precise dimensions of 9.37 by 7.02 by 5.39 millimeters, double cabochon cut, vivid color intensity, very slightly included clarity as evaluated at eye level, and an excellent polish. This is a gem that balances size and presence with the tactile, organic appeal of a cabochon finish, making it well suited to both classic and contemporary jewellery designs. The weight and dimensions place this stone in a category where the color and body tone can be fully appreciated without overwhelming the setting, and the oval outline provides a pleasing visual elongation when set in a ring or pendant. The translucent character allows light to penetrate and interact with the internal features of the sapphire, producing depth and color movement that cabochon lovers prize, while the excellent surface polish ensures a smooth, reflective finish that highlights the gem color and surface transparency.

Color is the principal driver of value in a blue sapphire, and this stone displays a vivid blue intensity that commands attention, yet remains natural in saturation and distribution. The term vivid in gemmological usage refers to strong saturation and balanced tone that deliver a lively visual impact without appearing inky or over dark, and that quality is evident here. Origin matters to educated buyers because geological source often correlates with certain color profiles and textures, and this sapphire comes from Ceylon, Sri Lanka, a region historically renowned for producing sapphires with lively cornflower blue tones and floral like sparkle. In this case the Ceylon origin contributes provenance that is both romantic and market relevant, and buyers who understand origin premiums will appreciate the nuance that a Sri Lankan source can add to desirability and comparability within the broader market.

The double cabochon cut is a deliberate choice that emphasizes the body color and the internal glow of the stone, rather than faceted brilliance, and it provides a symmetrical dome on both crown and pavilion that enhances visual depth and color saturation. Cabochon cutting is often selected for grenades with interesting inclusions or for gems whose color is best shown with surface curvature, and here the cut preserves weight while presenting the intense blue surface that cabochon collectors value. Clarity graded as very slightly included at eye level indicates that the stone is essentially clean to a quick visual inspection, with minor inclusions that do not detract from overall beauty or structural integrity. Those small internal features can in fact add character, and when paired with an excellent polish the result is a visually clean, silky surface that reflects light evenly and presents a stable, refined appearance suitable for everyday wear.

Disclosure of treatments is essential for trust and value assessment, and this sapphire has been heat treated, which is the most common and widely accepted enhancement in sapphires. Heat treatment in sapphires is used to improve color uniformity and remove or reduce color zoning, and when properly performed it is generally considered stable and permanent. Educated buyers should know that heat treated sapphires are standard in the market, and that disclosure is what separates reputable suppliers from the rest, which is why The Natural Sapphire Company lists the enhancement openly. Heat treatment does not necessarily reduce value when the resulting color and clarity are attractive, but origin, cut, size, and overall eye appeal remain primary determinants of price, so this stone benefits from a combination of vivid color, attractive cabochon form, and clear origin documentation.

From a practical perspective the double domed oval profile measures well for a statement ring or a pendant bezel, where the cabochon is protected and its color can be admired from multiple angles, and the 3.87 carat weight provides a substantial presence without requiring an overly large mount. For daily wear choose secure settings that protect the girdle and edges, such as bezel or halo styles, and for cleaning use warm soapy water and a soft brush to maintain surface luster, avoiding harsh chemicals and rapid thermal shocks which can affect any stone with internal features. For buyers interested in certification, The Natural Sapphire Company can assist with independent gemmological reports that document origin, treatments, and measured characteristics, which is useful for insurance and future resale. Finally this sapphire represents a strong choice for collectors and clients seeking a natural Ceylon blue with vivid color and classic cabochon appeal, and we are happy to provide additional images, magnified views, and setting recommendations to ensure the gem meets your expectations.
