Frequently asked questions

What is the price of cerium?

In 2024, the reference price for cerium stood at around 2.8 USD/kg, compared with 3.5 USD/kg in 2023. Prices vary with purity, form (oxide or metal) and traded volume; the full history is charted above.

How can a client hold physical cerium?

Cerium is held in a specified form (metal, oxide or compound) and purity, backed by a certificate of analysis for the lot. Procyon Metals works through wealth advisers and family offices: it sources from vetted counterparties, documents the lot and arranges transport and storage with a specialist custodian.

Why is cerium a strategic metal?

Foundation of automotive emissions control. Growing demand from hydrogen fuel cells and advanced glass manufacturing.

Which countries produce cerium?

Cerium production is highly concentrated: China (70%), Australia (12%), Myanmar (8%).

How liquid is physical cerium?

Less liquid than listed products: there is no exchange price for cerium that a private holder can trade on. Resale is negotiated with industrial buyers or traders, and the price and timing depend on form, purity, lot size and demand at that moment. It should be treated as a long-horizon holding.
