🔍 What Makes a Metal “Expensive”?

The price of a metal is driven by:

• Rarity: How scarce it is in Earth’s crust.

• Industrial Demand: Use in cars, electronics, medicine, or jewelry.

• Extraction Costs: Some metals are extremely hard or dangerous to mine.

• Geopolitical Supply: Controlled by a few countries (e.g., Russia, South Africa).

• Market Speculation: Investment trends and tech developments can skyrocket prices.
