AI-assisted summary
Description from the seller
Natural Brillant 0.31 ct – IGI “Ideal Cut” – sealed untouched since certification
A real, naturally grown diamond – formed millions of years ago deep in the earth and not a lab diamond. Cut to perfection and, since its examination by the renowned International Gemological Institute (IGI), originally sealed: No one has touched or replaced this stone since then.
What makes this diamond special – simply explained:
• Highest cut grade + “Ideal Cut”: IGI rates the cut, polish, and symmetry as “Excellent,” the top grade, and explicitly notes “Ideal Cut.” The cut determines how strongly a diamond flashes – here it is designed for maximum fire.
• Clarity VVS2 – top tier: Very, very small inclusions, invisible to the naked eye and extremely difficult to detect even for experts under 10x magnification.
• No fluorescence: No risk of a milky shimmer in sunlight – the stone stays clear and brilliant.
• Color J – near colorless: A fine, warm tone that looks particularly noble in yellow and rose gold settings and sparkles vividly in any setting.
• Tamper-evident sealed & engraved: Original in the IGI CertiCard security case sealed (with CertiEye security code) and laser engraving of the certificate number on the girdle. Always verifiable online at igi.org.
Certificate details:
• Certificate number: 502144444
• Place: Antwerp
• Date: 01.12.2021 (1 December 2021)
• The certificate contains further information.
