1.45 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This striking transparent yellow sapphire from Ceylon, Sri Lanka combines precise dimensions with exceptional visual appeal, making it a refined choice for the conscious collector. We present a single 1.45 carat emerald cut sapphire, measured at 6.88 x 4.89 x 3.97 mm, with an elongated step cut that emphasizes both depth of color and clarity. The gem has been assessed as eye clean when viewed at normal reading distance, which means that no inclusions are visible to the unaided eye. The intensity of the yellow is classified as intense, producing a saturated golden hue that remains lively under daylight and artificial lighting. An excellent polish enhances the stone interactions with light, allowing the plane like facets of the emerald cut to produce broad flashes and a smart, architectural elegance. This sapphire has been heat treated, a standard and widely accepted enhancement in the trade that stabilizes and intensifies color while leaving the fundamental structure of the corundum intact. At The Natural Sapphire Company we disclose this treatment because transparency in origin and enhancement is a cornerstone of value for educated buyers.

From a gemological perspective, this Ceylon yellow sapphire is notable for attributes that informed buyers prioritize, beginning with color chemistry and moving through cutting standards and finish quality. Yellow coloration in sapphire is commonly imparted by trace iron, and in material from Sri Lanka it often yields a warm, clear yellow rather than a muddy or overly brown tone. The emerald cut chosen for this gem is particularly effective at presenting even color distribution across the table, and it rewards careful faceting with large, even planes of color rather than a play of small scintillating facets. Because the clarity is eye clean, the emerald cut becomes an asset rather than a liability, showcasing the pure color without distraction from internal features. The excellent polish is a technical consideration that affects durability, light return, and the apparent crispness of the faceting. For collectors interested in longevity and wearability, this stone scores highly, given corundum hardness, the stable nature of heat treatment, and the professional finishing that reduces the risk of abrasion during setting and wear. The gem sits in a size range that is versatile for both solitaire settings and as a refined accent stone in bespoke designer pieces, offering balance between visual impact and everyday practicality.

Ethical sourcing and traceable supply chain practices are central to the value proposition of this sapphire, and at The Natural Sapphire Company we prioritize responsible procurement from the mine to the finished gem.
