1.45 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This 1.45 carat cushion shape yellow sapphire presents a precise combination of weight, proportions, and optical quality, attributes that are central to its value and desirability. Weighing 1.45 carats, this stone moves beyond ordinary sizes for yellow sapphires and into a range where scarcity and market demand begin to elevate per carat value. The dimensions 6.58 x 6.54 x 3.80 mm produce a near square face up presentation that maximizes visible surface area for a given weight, allowing the 1.45 carat mass to read larger to the eye than stones with less favorable proportions. The mixed brilliant cut complements the cushion outline by combining larger facet surfaces on the crown with precision lower girdle facets, delivering balanced brilliance and scintillation while preserving weight in the pavilion. For collectors and for fine jewelry applications the specific weight of this sapphire contributes directly to both its presence on the finger and to its monetary value because weight is a primary determinant in how the market prizes colored gemstones.

Clarity and transparency are important when assessing how effectively a gemstone’s weight translates into visual impact, and this sapphire has a clarity grade of very very slightly included when evaluated at eye level. In practical terms the stone appears transparent and eye clean in normal viewing, with only minute inclusions detectable under magnification. This high level of clarity allows light to travel through the 1.45 carat body without significant obstruction, so the stone’s weight contributes to brightness and depth rather than masking or clouding the color. The excellent polish enhances light return from all facets and accentuates the mixed brilliant cut, ensuring that the additional milligrams represented by the carat weight are expressed as clean, lively sparkle rather than lost to poorly finished surfaces.

Color and enhancement are essential components of overall value, and this sapphire exhibits a vivid yellow color intensity that benefits materially from the stone’s 1.45 carat weight. Vivid saturation in yellow sapphires is less common than more muted tones, and when vivid color is present in a stone of this size the combination is comparatively rare. The sapphire has been treated by beryllium diffusion, a widely recognized enhancement process that produces or intensifies yellow and orange hues by introducing trace elements into the gem during high temperature treatment. Full disclosure of this beryllium diffusion is provided because enhancement type affects market valuation and future care considerations. Untreated sapphires with similar hue and saturation at comparable weights typically command a premium, while a beryllium diffused sapphire of this quality offers the advantage of vivid color with a different price positioning. Buyers should consider that the 1.45 carat weight elevates the significance of the enhancement in pricing discussions, because larger stones with vivid color and documented treatments occupy specific segments within the trade.

Origin and presentation complete the technical profile of this sapphire, which is sourced from Ceylon Sri Lanka, a locality historically prized for producing bright and lively sapphire colors. The origin adds provenance value and contextualizes the stone within Sri Lankan material types known for clarity and attractive saturation. At 1.45 carats the gem is well suited to serve as a focal center stone for engagement or fashion rings, where the balance of face up area and depth will read elegantly on the hand, and where the confluence of vivid color, high clarity, and excellent polish will be immediately appreciable. The Natural Sapphire Company stands behind the accurate description and disclosure of this gem, and can provide detailed imaging and certification on request to confirm dimensions, weight, cut attributes, clarity observations, enhancement disclosure, and origin. For buyers and designers seeking a yellow sapphire where weight meaningfully contributes to visual presence and rarity, this 1.45 carat cushion shaped gem represents a considered and well documented choice.
