For many years, IPGL has been a source of trust and authority in the testing and certification of the finest gemstones and diamond jewellery. Our reputation for quality is what brings customers back year after year as their needs for diamond jewellery change.

As part of IPGL’s commitment to our customers, we recognize the concerns our customers have regarding the purity and authenticity of the diamond they are purchasing for their wedding, engagement, or anniversary. This has prompted us to develop methods for providing information regarding diamond buying, and our methods for analyzing and certifying them.
