1.09 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This cushion shape yellow sapphire weighs 1.09 carat, and its weight is a defining attribute of both its presence and market value. The gem measures 6.37 x 6.26 x 3.41 mm, and the proportions produced by its mixed brilliant cut yield a balanced face up presentation with notable brilliance. The stone is transparent, with a clarity grade of slightly included when evaluated at eye level, and it benefits from an excellent polish that enhances light return across the pavilion and crown facets. The color presents at medium intensity, a tone that allows the yellow hue to read clearly under a variety of lighting conditions while maintaining a refined, classic appearance. There has been no enhancement to this sapphire, and its recorded origin is Ceylon, Sri Lanka, a provenance that is well regarded for a long history of producing high quality yellow sapphires. The Natural Sapphire Company stands behind the factual details of this gem, and the combination of weight, cut, clarity, and origin describes a stone that is straightforward in its gemological character and attractive in its face up performance.

The carat weight of 1.09 is particularly meaningful for this sapphire, because weight in corundum is a core determinant of rarity and pricing dynamics. Carat weight corresponds directly to the physical mass of the crystal lattice, and as weight increases material of gem quality becomes exponentially less common. A gem that crosses the one carat threshold retains a psychological and commercial significance that often results in a proportionally higher price per carat relative to smaller sizes of similar quality. In practical terms the 1.09 carat weight here preserves enough material to support a well proportioned cushion cut with generous facet development, which in turn optimizes brilliance and scintillation without sacrificing weight to overzealous faceting. For an unenhanced sapphire from Ceylon the absence of treatment further amplifies the stone’s rarity profile, because many comparable stones in the market are heat treated to intensify color and improve clarity. The combination of natural, unenhanced material and a weight slightly above one carat places this sapphire in a tier where demand can outpace supply among collectors and fine jewelry makers who prioritize untreated origin material. Clarity inclusions are present but slight at face up inspection, and in this weight range such inclusions are consistent with natural Ceylon material and do not materially diminish the stone’s intrinsic value when considered alongside its color, cut, and polish.

From a practical perspective the dimensions and carat weight create a versatile physical presence suitable for single stone rings, pendants, and bespoke settings where the balance between table size and depth is important. At 6.37 x 6.26 mm the cushion shape will sit with a comfortable visual footprint on most fingers, and the mixed brilliant faceting pattern provides a play of light that reads larger than the raw millimeter measurement might suggest. Weight contributes to perceived value in the mounting phase as well, because a 1.09 carat sapphire offers more structural substance to support secure prong work and bezel applications without requiring excessive metal coverage that can obscure the gem. The medium color intensity renders the stone adaptable to a range of metal choices, and the excellent polish will help maintain a bright, lively face up appearance over time. For those assessing long term value, an untreated Ceylon sapphire of this weight benefits from both the tangible rarity associated with preserved carat mass and the less tangible premium that collectors attribute to documented origin and treatment status. The Natural Sapphire Company provides full disclosure of these attributes, and the factual combination of 1.09 carat weight, cushion shape, mixed brilliant cut, slightly included clarity at eye level, medium color intensity, excellent polish, absence of enhancement, and Ceylon Sri Lanka origin defines a gem that is technically well described, demonstrably rare relative to treated material, and practically suited to fine jewelry applications where weight and provenance are important considerations.
