EXAMPLE HGDL DIAMOND CERTIFICATE

  • London's Hatton Garden Diamond Laboratory (HGDL) certificate provides an independent verification of the grading of smaller carat weight natural mined diamonds used in diamond-set jewellery. These are also referred to as "melee diamonds."

  • Each certificate provides details of the precious metal of the jewellery item, the combined diamond carat weight, shape, colour and the clarity grouping, for example F-G/VS.

  • By nature of the size of melee diamonds, the amount of information provided is less extensive than for larger certified diamonds.
