Go through The Hidden Cost of Jewelry Report to find out whether the company you are researching owns manufacturing plants or facilities (i.e. if it integrates manufacturing into its operations).

If the company is not part of the Report, browse the Corporate Social Responsibility section of the company's Website and look for the information.

Usually, documents entitled Statement on Gemstone Sourcing, Conflict Minerals or Corporate Social Responsibility Report, may contain information about it.

• If you find that the company owns manufacturing plants or facilities, select “Yes”.

• If you find that the company has plans to acquire manufacturing plants or facilities, select “In Development”.

• If the company clearly states that it does not owns manufacturing plants or facilities, select “No”.

• If you cannot find information on this regard, select “Unknown”.
