A diamond certificate is a formal report issued by an accredited independent gemological laboratory, which lists gemological information about the diamond’s characteristics such as carat weight, measurements, cut, colour, and clarity. 

Diamond certificates provide all consumers with a degree of confidence that the diamond is genuine and has been accurately presented by a jeweler. Some laboratories also issue light performance certificates, grading diamonds on light reflection parameters (e.g. Sarine Light™).


How are Diamonds Certified?

Diamonds are sent to an independent gemological laboratory. Details such as company names, initials, logos or other information that may lead personnel to be biased in the certification process are omitted.


Certification Houses

Diamonds from Love & Co. are certified by reputable certification houses in the world, for instance International Gemological Institute (IGI) and De Beers Group Institute of Diamonds (IOD).


De Beers Group Institute of Diamonds (IOD)

A world leading corporation, De Beers Group is probably the most long standing company active within the diamond industry – from exploration, mining, trading, and retail. In 2017, they pioneered their own certification house – known as the De Beers Institute of Diamonds. Love & Co is the first Asia Pacific partner to collaborate with De Beers for certified diamonds.


Review a Sample Certificate Report (IOD)

Familiarise yourself with the look and orientation of a Diamond Grading Report by IOD to know which diamond is the best choice for you. Do note of the different areas of the report, which would tell you:

  • 4Cs of a Diamond
  • Accurate measurements of the diamond solitaire
  • Graphical display of the diamond inclusions
  • Actual hearts and arrows image of the diamond (only Love & Co.’s Lovemarque has this)
