Terms and Conditions

Last update 05 04 2017.

IDGL generates and sells grading certificates (the "Report") for loose diamonds and gem stones and said items mounted or incorporated into items of jewellery (the "Item"). Each Item is individually assessed.

A Report is not a guarantee. A Report is issued by an independent laboratory using our method of evaluation, based on the Gemological Institute of America grading system.

The weight of a mounted stone is calculated from measurements of the stone, and may differ from its actual weight. The grades issued can differ depending upon when, how and by whom the diamond is examined.

Our contractual obligations are with our customer, that is the business, limited company, agency, dealer or individual which comissions and purchases the Report. When or if the Item is sold, gifted or transfered in ownership by this party to a third party, our obligations remain with our customer. Our staff are always willing to field enqueries regarding any Report; however in the first instance any question regarding a Report and its relevance to the Item acquired should be made to the place or individual from whome the Item was acquired.

A Report is copyrighted and may not be reproduced in any form whatsoever. Any attempt to tamper with the presented data on the Report invalidates the Report. All data used to generate the Report is digitally archived and both locally and remotely backed up, and may be retrieved in case of dispute.

A copy or copies of the Report can be requested by our customers. This may be generated from our archived data, or from the Item being reassessed at our laboratory. A charge for such a service will be made at the discretion of IDGL. A copy or copies of the Report can be requested by a third party in posession of the Item and its Report, or such representatives they have appointed. This may be generated from our archived data, or from the Item being reassessed at our laboratory. A charge for such a service will be made.
