two-colour Sapphire 1.02ct

Two colors. One stone. One heart.

What might sound like a creative concept is, in this case, simply nature at work. This 1.027-carat sapphire displays two clearly distinct color zones within a single crystal – blue and yellow, or depending on the light, a bluish green and yellow. The GLA and ALGT have each issued their own report and describe the color slightly differently, which only underscores how lively and shifting this stone's appearance truly is.

The heart cut is not a gimmick here – it is a considered choice that gives shape to the stone's inherently emotional quality. At 6.02 × 6.26 mm, the heart is nearly perfectly proportioned, marginally wider than tall, resulting in a balanced and harmonious silhouette.

Very minor inclusions, untreated – the ALGT explicitly confirms no indications of thermal treatment. Bicolor sapphires develop through natural color zoning during crystal growth. What you see here was shaped entirely by the earth, without human intervention.

For someone looking for a sapphire that stands apart – and has something to say.

The appraisal for this blue sapphire has been issued by the Gemological Laboratory Austria (GLA). A replacement value of €800 has been determined.
