Natural Big Yellow Sapphire 21.39ct Cushion Cut Lead-Glass Filled

This bold lead-glass filled African sapphire makes a striking visual statement at over 21 carats, presenting a vivid warm orange-amber colour that glows richly through the large cushion-cut face. The colour is deep, warm, and saturated, transitioning between golden amber and bright orange tones across the substantial 15x14.2mm face. The cushion cut suits the stone's generous proportions beautifully, and the lead-glass filling has significantly improved the visual clarity to produce an eye-catching appearance at an accessible price point for this carat size.

Lead-glass filling is a clarity enhancement treatment applied to heavily included corundum, using leaded glass to fill surface-reaching fractures and dramatically improve transparency. This treatment is fully disclosed and should be considered when purchasing. The stone requires gentle care, avoiding steam cleaning and acid exposure. From Africa, this sapphire is a bold choice for statement cocktail rings, large pendants, and display pieces where size and warm colour are priorities.
