1.00 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

One of the finest expressions of Ceylon sapphire craftsmanship, this transparent 1.00 carat radiant shape yellow sapphire measures 7.06 x 5.05 x 3.02 millimeters, and is offered by The Natural Sapphire Company. The stone displays an intense color intensity that reads as a vivid sunshine yellow, with a clarity grade described as very very slightly included when evaluated at eye level, and an excellent polish that gives each facet razor sharp definition. The radiant cut, chosen for this gem, unites the lively brilliance of a round cut with the elegant octagonal silhouette of a step cut, and the result is a gem that balances color, depth, and sparkle with remarkable poise. This sapphire has been heat treated, a widely accepted enhancement that stabilizes and amplifies the gem's natural hue while preserving its integrity, and its Sri Lankan origin contributes a provenance prized by collectors for bright, clean tones and consistent crystalline quality.

What truly sets this sapphire apart in the market is the geometric faceting that the radiant shape allows, and the way that faceting maximizes light play compared with many alternate options. Radiant faceting uses a complex pattern of small, precisely angled facets on both the crown and pavilion, creating a mosaic of light return that produces intense scintillation and broad flashes of color. Against stones that are simply large or deeply colored, this gem demonstrates that superior cutting geometry can deliver greater perceived size and liveliness per carat. Compared with emerald and baguette shapes that emphasize linear reflections and hold color in broad flashes, the radiant cut scatters light across many facets to generate lively sparkle from most viewing angles. Compared with round brilliants, which can sometimes sacrifice face up color for maximum white light return, this radiant yellow sapphire preserves strong, saturated color while still offering lively brilliance, making it ideal for a setting where color presence matters as much as fire. The gem sits at a depth that translates to approximately fifty percent relative to its face dimensions, a proportion that helps concentrate color in the table face while maintaining excellent return of white and colored light, a balance not always found in shallower or deeper cuts.

From a value and rarity perspective, this sapphire represents a superior choice for buyers who want both immediate visual impact and long term satisfaction. Many yellow sapphires on the market compromise either clarity, color, or cut to hit a price point, leaving the wearer with a stone that looks flat or shows distracting inclusions. This gem's very very slightly included clarity means that at normal viewing distances the stone reads as eye clean, so the intense yellow is uninterrupted by visible inclusions, and the excellent polish ensures that facet junctions act as tiny mirrors rather than light traps. Origin matters, and Ceylon sapphires are consistently sought after for their pure and vivid tones, making this gem more desirable than comparable stones from less established sources. Heat treatment is disclosed and stable, enhancing the stone without disguising its natural character, and when paired with a skilled setting it outperforms many untreated stones that lack precision cutting. For those considering mounting options, the radiant geometry works exceptionally well in both solitaire and halo designs, where its faceting produces strong reciprocal brilliance with surrounding accent stones, and in more modern bezel or tension settings that showcase the gem's octagonal silhouette. When you choose this sapphire through The Natural Sapphire Company, you are selecting a gem that stands above common market offerings in terms of cut quality, optical performance, and overall presentation, and our gem specialists can assist with setting recommendations that preserve the stone's maximum light play and color saturation.
