detailed Description

Blue like a deep evening sky – this 4.64-carat sapphire from Madagascar arrives with a color that commands attention immediately. The rich, vivid blue carries an intensity that is characteristic of sapphires from this origin – Madagascar is recognized as one of the most significant sources for strongly saturated sapphires in the world.

At 11.06 x 8.93 x 5.20 mm, it is a stone with tangible size and weight. The oval cut flatters the color beautifully – it offers light many paths through the stone, ensuring the blue reads evenly and with life. Medium inclusions are present, as is not uncommon in natural sapphires of this size – they speak to the stone's formation deep within the earth.

Particularly noteworthy: both GRS – Gemresearch Swisslab and GLA – Gemmological Laboratory Austria confirm no indications of thermal treatment. For a sapphire of this size, that is a statement worth noting – two of the most respected laboratories in the field, one clear result.

A blue sapphire with provenance, presence, and weight – for collectors and connoisseurs alike.
