Trade Information


GemLab is proud to announce that it is one of only two New Zealand Jewellery Valuation Companies to have been granted membership to the International Association of Independent Jewellery Valuers.

If you are a Jeweller who would like to offer a professional independent valuation service to your customers, or who could use ethical independent documentation to help sell your stock, click here (opens online enquiry form)

As a Jeweller your mission is to make and sell Jewellery that your customers want to buy. And to provide the quality and service that your customers expect. You want to be seen as trustworthy and ethical in all your business dealings. This is where GemLab can help you achieve your goals. We are proud that our Diamond Reports and Jewellery Valuations are regarded as the most ethical, the most accurate, and the most independent in New Zealand. Reports that your customers can rely on.

We do not buy or sell diamonds or jewellery. GemLab is the only valuation company in New Zealand that explicitly prohibits trading in its employment agreements.

We will not provide misleading pre-rendered "insurance" type valuations on stock items to your competitors.

In addition to diamond grading and gemmology, we have a deep understanding of Valuation Science and how the Insurance of Jewellery really works.
