This 4.51ct ruby gemstone features a classic oval cut and vibrant strong red colour. Measuring 10.4mm x 8.1mm x 6.1mm, it has an SI2 clarity grade, with visible inclusions when viewed by eye.
The stone exhibits strong red fluorescence under UV light and high thermal conductivity consistent with the corundum family (ruby/sapphire mineral group). These properties are often associated with both natural and synthetic rubies.
The gemstone is accompanied by a certificate from GISA (Gemology Institute of Southern Africa), offering independent verification of its physical and optical characteristics.
