How can you be sure that the diamond you bought has the quality it was advertised for? This is the mission and purpose of the diamond grading laboratories. They examine and measure the diamonds and provide a certificate that matches internationally agreed standards. The diamond certificate or diamond passport guarantees and describes the quality for each unique diamond.In the certificate you will find the values to capture the 4 c's of diamond quality : clarity , colour , carat and cut. The certificate also allows to identify each unique diamond and can be used in case of theft or loss to prove the diamond ( or engagement ring) is your property.
Around the world, IGI certificates bring confidence when buying or selling diamonds, gemstones and jewelry. Total commitment to understanding consumer concerns has motivated IGI to develop comprehensive analysis and clear documentation for consumers. This empowers jewelry buyers to focus on finding precisely what they want, with full assurance in the integrity and quality of the IGI certification. IGI is the largest organization of its kind, with operating laboratories & offices in Antwerp, New York, Hong Kong, Mumbai, Bangkok, Tokyo, Dubai, Tel Aviv, Toronto, Los Angeles, Kolkata, New Delhi, Thrissur, Jaipur, Surat, Chennai, Ahmedabad and Hyderabad
The HRD Antwerp diamond lab is the largest diamond lab in the world that issues reliable diamond certificates, grading and jewellery reports fully compliant with the rules for grading polished diamonds set by the International Diamond Council (IDC)
Established in 1931, GIA is the world’s foremost authority on diamonds, colored stones, and pearls. A public benefit, nonprofit institute, GIA is the leading source of knowledge, standards, and education in gems and jewelry.
We did not only select these because they are reputable diamond grading labs but in addition they provide the diamonds with a certificate and packaged in a sealed container.
Sealing guarantees that a given certificate and the corresponding diamond belong together, and it keeps the diamond safe from oil and dirt. The sealing is tamper-proof and will show when opened or tampered with.
Although all Diamond Grading Laboratories will inspect diamonds using microscopes at very high magnification ( 40x +) , the actual grading only occurs at 10x magnification, this is why HRD will not grade higher than 'Loupe Clean' ( LC).
Other Gemological Institutes ( IGI, GIA etc ), have opted for 'Internally Flawless' ( IF) as their highest grade. Since some diamonds may be slightly 'blemished' on their surfaces ( although this does not really affect the Clarity of the diamond ), GIA has added 'Flawless' to its grading in order to distinguish between the Internally Flawless ( Loupe Clean ) and those who are NOT only IF/LC but also totally 'unblemished'.
Once that a diamond is worn or handled, the chances are that it will lose its FL grading, since as soon as a diamond makes contact with any hard object, it will be slightly 'blemished'. As far as Clarity is concerned, IF and LC are the highest.
