Sensible Sourcing

Recognizing the challenges associated with providing precious materials in a responsible manner, it is our goal to continually work closely with our suppliers in order to ensure our products are produced in the most ethical way possible.

Sensible Sourcing


Gold and other precious metals should be mined and refined in a sustainable and responsible manner that respects both the needs of humanity and our environment.

Our position on responsible mining procedures goes much further than the gold mining process itself. It encompasses all aspects of gold: appropriate mining methods on conservation, remediation and fair labor practices. It also includes proper refining; correct handling of aqua regia acid, scrubbing fumes, and clean emissions.

Only specific, branded gold bars and grain are acceptable in our production operations. And we internally recycle up to 98% of raw materials used in our production.

We require that our vendors maintain policies and procedures, which mandate social and environmental responsibility for both themselves and their suppliers.

SCS Certification

As proof of our commitment to sustainability, Stuller has earned a recycled content certification in an SCS audit. SCS is a global leader in verification of environmental and sustainability claims with internationally recognized standards, and their certification ensures that all of Stuller's manufactured metals—gold, silver, platinum, and palladium product—is certified 100% recycled content.

Stuller sources the majority of its diamonds directly from sources that manufacture rough diamonds from Canada, South Africa, Russia, Botswana and Namibia.

No Conflict Diamonds

We are committed to selling diamonds ethically and with integrity, giving you confidence in the diamonds you purchase. We believe it is completely unacceptable to tolerate conflict diamonds and/or human suffering in any way and we fully support the Kimberley Process. Stuller Inc. offers this commitment to you. In turn, it can act as your commitment to your customers. All rough and polished diamonds sold by Stuller Inc. comply with the Kimberley Process. The Kimberley Process ensures that rough diamonds are:

  • Exported and imported with a government validated Kimberly Process certificate stating the diamonds are conflict-free.
  • Transported between signatory countries in a sealed and tamper-proof container.
  • Sold with a statement from the seller (known as a warranty) on all invoices guaranteeing that the diamonds being sold are conflict-free.

Synthetic Screening Policy

When you buy diamonds from Stuller, you can buy with confidence. We do not tolerate undisclosed synthetic diamonds in our inventory. In July 2014, we acquired the De Beers Automatic Melee Screening Device (AMS), which screens all diamonds 1.4mm+ for synthetics in accordance with De Beers’ protocols. We require all our loose diamond and diamond set jewelry suppliers to warrant that they are not supplying us with synthetics. For additional security, we further stipulate that our vendors screen all diamonds from .20+ carats for synthetics.

Diamond Manufacturers and Importers Association of America

We are proud member of the DMIA.

Established in 1931, the mission of DMIA is to promote the highest standards of ethics, integrity and professionalism in the American marketplace. The DMIA, remains at the forefront in addressing domestic and world diamond industry issues, acts as a representative for the American diamond industry together with other industry organizations, governmental bodies, and the diamond consuming public.

The DMIA is dedicated to advancing and ensuring consumer confidence in diamonds and diamond jewelry.

Canadian Diamond Code of Conduct

The Code establishes a minimum standard based on records and a chain of warranties required to validate a Canadian diamond claim. Retailers who abide by the Code demonstrate to consumers their commitment to ensure authenticity of Canadian diamond claims. The Code allows Canadian diamonds to be traced from the Canadian mine to the diamond jewellery retailer, providing consumers a method to authenticate Canadian diamonds sold by a Code member.


Stuller continues to adhere to strict protocols in regards to the sourcing of gemstones. As a natural resource, gemstones can be found almost anywhere and are exchanged too frequently to keep an absolute accurate account of their exact origin.

However, we engage in several practices to ensure the integrity of the stones we purchase. For example:

  • Experts from both our US and Bangkok offices frequently visit our suppliers/cutters in order to make certain socially responsible practices are being followed in those locations.
  • All of our suppliers have provided written verification stating their compliance with the US Patriot Act.
