1.31 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This 1.31 carat yellow sapphire presents as a transparent, emerald cut shape with exact dimensions of 6.99 by 4.89 by 3.98 mm, sourced from Ceylon Sri Lanka and heat treated to optimize tone and clarity. The stone displays intense color intensity, and a clarity grade of very slightly included when evaluated at eye level, indicating minor internal characteristics that do not interrupt the visual field or compromise light transmission. The emerald cut employs broad step facets and a generous table, creating linear flash patterns and a hall of mirrors effect, while the pavilion steps have been proportioned to return light evenly and to preserve saturation. The excellent polish and precise facet junctions reveal expert lapidary work, and the combination of proportion control and facet alignment results in crisp facet planes, predictable light return, and a sizeable visual face up area for its carat weight.

Compared to more common yellow gemstones such as citrine and yellow topaz, this Ceylon sapphire stands apart by virtue of higher density, stronger refractive properties, and a more stable, saturated hue, producing broader, deeper flashes rather than the feathery dispersion typical of lower index stones. Against brilliant cut stones and diamonds, the emerald cut sapphire emphasizes broad flashes of color and high contrast reflections rather than the intense scintillation and fire seen in high dispersion materials, this quality is an advantage for buyers seeking elegant, architectural sparkle. The intense yellow saturation maximizes perceived brilliance within the sapphire s lower dispersion by providing vivid body color and pronounced contrast between table and step facets. For setting, an open prong or low bezel with an open gallery will allow maximum light entry to the pavilion and enhance the step facet flash, whereas a heavy closed setting may reduce apparent luminosity. At The Natural Sapphire Company this gem is presented with attention to provenance, cutting quality, and natural characteristics, making it ideal for a refined solitaire or a bespoke design where clarity, color saturation, and the distinctive step cut aesthetic are the primary considerations.
