Gold and silver dominate much of the precious metals market, but they are not the only metals attracting attention. Platinum, palladium, rhodium, ruthenium, iridium and osmium each have unique properties, industrial applications and supply challenges that influence their value.
For investors interested in understanding the broader precious metals market, these six metals offer an insight into the relationship between scarcity, industrial demand and global supply.
The Six Metals and Their Uses
1. Platinum (Pt)
Platinum is used in fine jewellery, automotive catalytic converters, chemical processing and emerging hydrogen technologies. It is also available in physical investment bars and coins, making it one of the more established precious metals for investors.
2. Palladium (Pd)
Palladium is particularly important in automotive catalytic converters, which help reduce harmful vehicle emissions. It is also used in electronics and dentistry. Its price can be heavily influenced by automotive demand, substitution by platinum and supply conditions.
3. Rhodium (Rh)
Rhodium is a rare and valuable metal used primarily in vehicle emissions control, chemical catalysts and specialist plating. Its relatively limited market can result in substantial price movements when supply and demand become unbalanced. However, it can be difficult to buy and sell compared with gold and silver.
4. Ruthenium (Ru)
Ruthenium has specialist applications in electronics, electrical contacts and chemical catalysts. Its importance is largely industrial, and it has a more specialised market than the major investment precious metals.
5. Iridium (Ir)
Iridium is exceptionally rare and highly resistant to corrosion and extreme temperatures. It is used in specialist electronics, high-temperature equipment and certain electrolysers involved in hydrogen production. Its specialised applications make it important to several advanced industrial processes.
6. Osmium (Os)
Osmium is an extremely dense metal with niche applications in specialist alloys, scientific instruments and research. Although it attracts interest from some collectors and specialist buyers, its market is considerably less established than those for gold, silver and platinum.
Which Metals Are the Most Valuable?
There is no permanent ranking of these metals by price. Their relative values change according to industrial demand, available supply, purity and broader economic conditions.
Rhodium has historically traded at prices substantially higher than gold during periods of severe supply constraints. Iridium can also command high prices because of its rarity and specialist applications, while platinum and palladium have more established commercial markets.
However, a high price per ounce does not automatically make a metal a better investment. Market liquidity, transaction costs and the ability to resell physical holdings are equally important considerations.
Where Are These Metals Mined?
The production of platinum group metals is concentrated in a relatively small number of countries.
- South Africa: The world’s leading source of platinum group metals, with major deposits in the Bushveld Complex.
- Russia: A significant producer of palladium and other platinum group metals.
- Zimbabwe: An important producer of platinum and associated metals.
- Canada: Produces platinum group metals, often as a by-product of nickel and copper mining.
Because production is geographically concentrated and extraction and refining can be complex, supply disruptions can have a substantial impact on individual metal markets.

What Should Investors Consider?
Although all six metals are often grouped under the precious metals umbrella, they do not all serve the same purpose in an investment portfolio.
Platinum, palladium and rhodium receive the most attention in commercial precious metal markets, largely because of their industrial importance. Ruthenium, iridium and osmium have more specialised applications and less accessible markets for many investors.
Before considering any of these metals, it is worth examining:
- Supply and production: How much metal is produced annually, and how concentrated is that supply?
- Industrial demand: Which industries rely on the metal, and how might new technologies change consumption?
- Market volatility: How sensitive is the price to supply disruptions and changing demand?
- Liquidity: How easily can physical metal be purchased, verified and resold?
- Trading costs: What premiums, refining charges and resale discounts may apply?
The Bigger Picture
Gold and silver remain the best-known physical precious metals, but understanding platinum group metals helps illustrate a broader point: scarcity alone does not determine value. Industrial demand, supply constraints, market accessibility and investor confidence all play a role.
For anyone researching physical precious metals, it is important to understand not only what a metal is worth today, but also how practical it is to own and sell.
