About IDGL

IDGL - International Diamond & Gem Laboratory - specializes in diamond grading and gemstone identification. We help individuals and jewelry professionals understand the materials they handle through gemological examination, laboratory reporting, and accessible education.

Behind every enquiry is a practical question. A buyer wants to understand a diamond's quality. A family wants to identify an inherited gemstone. A jeweler needs clear documentation to support a product description. These situations differ, but they share the same starting point: a need for information that can be understood and used.

Our purpose

Our purpose is to make diamond and gemstone information clearer. A stone's beauty may create the first impression, but its identity and characteristics deserve a closer look. Laboratory information helps connect what a person sees with a more precise description of the material.

We believe that a useful report should be accompanied by a clear understanding of what it covers. Knowing the limits of an examination is part of understanding its results.

More than a name on a document

For many people, technical terms are the most difficult part of reading a report. A carat weight is not a measurement of visible size. A natural-origin statement does not necessarily mean a gemstone is untreated. A geographic origin opinion is not the same as a complete ownership history.

Our website brings these distinctions into focus. Through service information, report guides, and educational articles, we help readers approach gemological questions with greater confidence.

For owners and buyers

Whether you are exploring a first purchase or learning about a stone you already own, you deserve to understand the information presented to you. We encourage you to read complete reports, preserve supporting records, and ask about any wording that is unclear.

The right enquiry does not need to begin with expert terminology. Tell us what the stone has been described as and what you would like to know.

For the jewelry trade

Clear material descriptions support clearer communication between businesses and their customers. Reports can help organize discussions of identity and quality, while accurate disclosure keeps treatment and origin information connected to the item.

For professional enquiries, share your materials, submission requirements, and intended use of the reports so that the available service can be discussed in the right context.
