1.01 Ct. Orangish Yellow Sapphire from Ceylon (Sri Lanka)

This transparent 1.01 carat orangish yellow sapphire presents itself in a radiant shape with precise dimensions of 6.06 by 5.07 by 3.60 millimeters, offering a compact and highly wearable size that performs exceptionally well in most fine jewelry settings. The gem displays an intense color intensity that sits squarely in the desirable range for yellow and orange sapphires, and its excellent polish allows the surface to act as a clean window into the gem. When measured against its average face dimension, the pavilion depth works out to approximately 65 percent, a proportion that is well suited to balanced light return and lively face up appearance. This particular stone has been evaluated as very very slightly included at eye level, meaning that to the unaided eye it presents as essentially clean, while minute inclusions may be revealed only under magnification. Origin is Ceylon Sri Lanka, a source well known for producing lively yellow and golden sapphires, and the stone has undergone beryllium diffusion enhancement to achieve and stabilize its vivid orangish yellow hue.

The radiant cut of this sapphire is a deliberately geometric and technical approach to faceting that combines the best attributes of step cuts and brilliant cuts, and is engineered to maximize light play. The cut features trimmed corners and an array of crown and pavilion facets that break incoming light into numerous small flashes of brightness and color, producing both scintillation and a strong sense of depth. The precise angling and symmetry of the facet junctions are fundamental to the gem's optical performance, with tight facet alignment and a well controlled table directly contributing to lively return of light rather than leakage into dark areas. Additionally, corundum's inherent optical properties, including a refractive index in the range expected for sapphire and a notable dispersion, work in concert with this facet geometry to intensify fire and brilliance. The result is a stone that radiates visual energy from multiple viewing angles, making the radiant faceting especially effective for a vivid orangish yellow that benefits from both flash and uniform color presentation.

Clarity and finish are important technical factors that influence both aesthetics and value, and this sapphire's very very slightly included grade indicates exceptional clarity for its class. Evaluated at eye level, the inclusions are minimal and do not interrupt the gem's overall transparency or brilliance, and the excellent polish further reduces surface diffusion of light so that the internal faceting can perform optimally. The origin of Ceylon Sri Lanka adds context to the stone's character, as sapphires from that region are often prized for their clear, bright tones and attractive saturation, and collectors and connoisseurs frequently seek Ceylon pieces for their classic color profile. It is also important to be explicit about treatments. This sapphire has been subjected to beryllium diffusion to enhance its orangish yellow tone. Beryllium diffusion is a well established treatment in the trade that can produce vibrant and stable color diffusion into the crystal lattice. Because treated stones may be priced differently than naturally colored, untreated material, full disclosure accompanies every sale, and documentation regarding treatment is available to support transparent valuation and comparison.

For practical considerations, this 1.01 carat radiant sapphire is an excellent candidate for a center stone in a ring, a pendant, or a bespoke piece that benefits from concentrated color and scintillation. Corundum's hardness of nine on the Mohs scale renders it durable for daily wear when set responsibly, and the radiant cut with its trimmed corners lends itself well to prong or bezel settings that protect vulnerable edges while still showcasing the stone's optical performance. Care recommendations include gentle cleaning with warm soapy water and a soft brush to maintain the polish and clarity, and consultation with a professional jeweler is advised before subjecting any treated sapphire to ultrasonic or steam cleaning.
