1.83 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent 1.83 carat oval yellow sapphire measures 7.79 x 5.98 x 4.48 mm, and it has a mixed brilliant cut that balances scintillation with focused color, producing lively fire and strong face up brilliance. The clarity is described as very very slightly included, assessed at eye level, which means the stone is effectively eye clean to most observers while still retaining natural internal characteristics under magnification. The color intensity is intense, presenting a clean, saturated yellow that benefits from the precision of the cut and the excellent polish. Origin is Ceylon Sri Lanka, a classic source renowned for producing sapphires with bright, pure tones and lively transparency. Enhancement is beryllium diffusion, a deliberate high temperature treatment that introduces trace elements to modify and stabilize color deep into the corundum structure. This enhancement can yield vibrant and evenly distributed hues that are stable in normal wear, and full disclosure of this treatment is an important part of responsible gem description and valuation.

Owning this sapphire is an investment in both beauty and craftsmanship, because the gem combines desirable physical attributes with reliable provenance and professional finishing. Corundum is one of the hardest gem materials, which means a well set and properly cared for yellow sapphire can be enjoyed daily with minimal risk of wear, while the mixed brilliant cut was specifically chosen to optimize light return and color saturation for this size and shape. Collectors and educated buyers value intense, well proportioned stones from Ceylon, and buyers should understand that beryllium diffusion alters market classification and pricing relative to untreated material, while offering a visually striking result that is long lasting. At The Natural Sapphire Company we emphasize ethical sourcing, transparent reporting of origin and treatments, and expert cutting and polishing, so this sapphire is offered with the kind of documentation and expertise that supports long term appreciation. Whether mounted as a center stone for a custom ring, or held as part of a curated gemstone collection, this yellow sapphire is an enduring statement of natural beauty and skilled lapidary work, backed by provenance and full disclosure from The Natural Sapphire Company.
