賣家描述
Natural Blue Sapphire 10.09 ct – Unheated – Pear Cut – GIA Certified
Impressive 10.09 ct natural blue sapphire, with no indications of heating, accompanied by an original GIA Sapphire Report.
A substantial natural sapphire weighing over 10 carats, featuring an elegant elongated pear shape and measuring an impressive 16.97 mm in length.
The sapphire displays a deep blue colour.
Its appearance varies considerably according to the direction and intensity of the light: under normal lighting it presents a deep, dark blue appearance, while stronger transmitted light reveals vivid and intense blue tones.
Gemstone details according to the GIA report:
• Species: Natural Corundum
• Variety: Natural Sapphire
• Weight: 10.09 ct
• Colour: Blue
• Transparency: Transparent
• Treatment: No Indications of Heating
• Shape: Pear
• Crown cutting style: Brilliant Cut
• Pavilion cutting style: Step Cut
• Measurements: 16.97 × 10.97 × 6.92 mm
• Geographic origin: Not Requested
• Laboratory: GIA – Gemological Institute of America
• GIA Report No.: 7531799686
• Report date: 30 October 2025
Particularly noteworthy is the combination of its large 10.09 ct weight and the absence of indications of heating, as documented by GIA.
Its elongated pear cut gives the gemstone a striking presence, while the faceting produces contrasting reflections and flashes of blue as the stone is moved through different lighting conditions.
The photographs show the actual gemstone offered for sale from multiple angles and under different lighting conditions. Some photographs demonstrate its normal deep-blue appearance, while photographs using transmitted/backlighting are included specifically to illustrate the blue colour visible when light passes through the gemstone.
As a natural gemstone, internal characteristics and inclusions may be visible under close examination and magnification. No attempt has been made to conceal the natural characteristics of the stone in the photographs.
The sapphire will be supplied together with its original GIA Sapphire Report.
An impressive large-format natural sapphire for collectors, gemstone enthusiasts or as the centre stone for a distinctive custom jewellery project.
Please examine all photographs and the GIA report carefully, as they form an integral part of the description.
