Shipping A Refining Lot

Advice to help jewelers get the best return

(Originally published October 2021)

Note: This primer on when and how to send in a refining lot is adapted from the digital publication A Refined Approach: Tips for Capturing Precious Metals, Choosing a Refiner, and Maximizing Returns (MJSA Press, 2021). The book offers a comprehensive approach to ensuring you can effectively manage your metal inventory, capture metal waste, and prepare your lot for refining. It also explains the sampling and assaying processes, as well as provides an overview of witnessing (in which you or a representative can see the lot being sampled) and umpiring (in which an independent party is brought in to test a sample and settle a dispute).
