How a product is defined
The assay defines it
A product is not a name. It is a specification on a lot, and a lot enters our catalog only when it passes four steps.
Step 01
Lot
A traceable lot, tied to a title and a producer.
Step 02
Assay
Independent laboratory assay on sealed samples.
Step 03
Documents
Origin, chain of custody and transport papers to bank standard.
Step 04
Offer
A written offer, and not before.

If you produce a mineral on this list, or need one delivered, use the pages for producers and for buyers. If your material is not listed, say so: the list follows the market.
The assay defines the product.
Nothing on this page is an offer. No price, quantity or availability is stated. The forms listed are those we work or intend to work; none is a statement of stock.
