11.09 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional Sri Lankan blue sapphire from The Natural Sapphire Company is an impressive 11.09 carat oval, measuring 14.84 by 12.21 by 7.22 mm, with a mixed brilliant cut that balances scintillation and depth, intense color intensity that reads as a vivid medium to strong blue, and an excellent polish that optimizes light return. Clarity is described as very very slightly included as evaluated at eye level, which to an educated buyer means minimal visible inclusions and outstanding transparency for a natural sapphire of this size, delivering both brilliance and a clean face up appearance. The stone has been heat treated, a stable and widely accepted enhancement that improves color saturation without compromising durability, and its Ceylon origin is important to collectors because Sri Lankan sapphires are renowned for their lively cornflower to velvety blue tones, and historically strong market demand, which supports both aesthetic and investment value.

For customization this sapphire is particularly versatile, the generous oval spread and 7.22 mm depth make it ideal for a wide range of settings from classic solitaires to intricate bespoke designs, it will sit beautifully as the centrepiece of an engagement ring, where a four or six prong setting will showcase the table and allow maximum light, or in a halo design to amplify perceived size and contrast the intense blue, it also adapts well to three stone rings, pendant necklaces, or a bold cocktail ring. The mixed brilliant cut gives excellent fire when paired with white metals, and the intense blue benefits from warm yellow gold to add richness, or platinum and 18 carat white gold to emphasize crisp brilliance, bezel settings offer extra protection for everyday wear while prong settings maximize light performance, and custom mounting can account for the stone depth to ensure correct girdle placement for secure, low profile, or high crown designs. Commissioned combinations are straightforward, we can recommend complementary side stones such as certified diamonds for a classic look, or colored gem accents for a modern palette, and we will provide exact measurements and mounting diagrams to ensure secure, proportional, and wearable designs that respect the sapphire frame.
