Description from the seller
Exceptional 2.20 ct Natural Pigeon's Blood Ruby – GUILD Certified, Unheated, Mozambique
Offered for auction is a truly rare and investment-grade gemstone: a 2.20 carat faceted natural ruby, accompanied by a full Engagement Report from the prestigious GUILD laboratory (No. 3109969438).
This ruby possesses the most coveted and prestigious color grade in the gemstone world – Pigeon's Blood. Per the certificate, the color is graded as "Vivid to Deep Red," giving it incredible saturation and fire.
The cut is a Cushion Modified Brilliant, which maximizes the gem's brilliance. Its dimensions are 8.12 x 7.29 x 4.61 mm, giving it an excellent presence.
Crucially: The certificate explicitly states "No indication of thermal enhancement." This means the ruby is completely unheated, and its superb color and clarity were not achieved through heat treatment, making it exceptionally rare and valuable to collectors.
This is the perfect centerpiece for a high-end engagement ring or a valuable addition to any collection.
