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

This listing describes one opaque blue sapphire, weighing 9.12 carats, presented in an oval shape with dimensions of 14.53 x 9.43 x 6.41 mm. The gem has been fashioned as a cabochon cut, a form chosen to emphasize depth of color and surface luster rather than faceted brilliance. The cabochon profile is well executed, maintaining balanced proportions across the length, width, and height, and delivering a smooth dome that reads as substantial in hand. The overall appearance is intentionally classic and restrained, consistent with traditional treatments used to showcase the intrinsic tonality of a deep blue sapphire, and this example is offered through The Natural Sapphire Company.

The sapphire grades as very slightly included when evaluated at eye level, a clarity assessment that indicates only minor internal features that do not materially affect the gem when viewed in typical presentation conditions. The surface finish is described as excellent polish, which contributes to a glossy, reflective face across the cabochon. Color intensity is characterized as dark, producing a saturated blue that favors depth over brightness, and the opaque character limits light transmission while enhancing the perception of uniformly deep tone. Under direct lighting the stone presents a rich, concentrated blue with subtle variations in depth across the dome, and the even polish aids in consistent visual appeal from multiple angles.

This stone has undergone heat treatment, an established and stable enhancement applied to sapphires to optimize color and clarity without compromising structural integrity. Heat treatment is a widely accepted practice within the trade, and when performed in a controlled manner it yields enduring results that are stable under normal wear and cleaning conditions. The origin is identified as Ceylon Sri Lanka, a source noted historically for producing sapphires with a characteristic palette that can include vivid and deep blues. The combination of Ceylon origin, cabochon form, and heat treatment results in a gem that carries the regional character in an accessible, polished presentation.

Recommended applications for a sapphire of this size and configuration include use as a focal element in a bespoke ring, a substantial pendant, or a statement piece that benefits from a smooth, domed surface. The cabochon format lends itself particularly well to bezel settings or low profile mounts that protect the surface and complement the stone ecology of light absorption and surface sheen. Routine care can be performed with warm, soapy water and a soft cloth, avoiding abrasive cleaners and prolonged exposure to harsh chemicals, and professional cleaning is advised if the setting design accumulates residue.
