Palladium is one of the world’s most important precious metals — critical to automotive industry, electronics, and increasingly relevant in fine jewelry. Here is what it is, why it has value, and how it compares to platinum and gold.
Quick answer: what is palladium?
Palladium is a rare, silvery-white precious metal in the platinum group metals (PGM) family, alongside platinum, rhodium, ruthenium, iridium, and osmium. Its chemical symbol is Pd and its atomic number is 46. Palladium is valued for its rarity, corrosion resistance, and exceptional catalytic properties — particularly its ability to facilitate chemical reactions at lower temperatures than platinum.
Palladium properties
Palladium is significantly lighter than platinum — approximately 12.0 g/cm³ density versus platinum’s 21.4 g/cm³. This makes palladium jewelry noticeably lighter to wear than equivalent platinum pieces. It is highly resistant to corrosion and tarnish in air and is naturally hypoallergenic, making it a good white metal option for people with nickel sensitivities. It has a relatively low melting point for a precious metal (1,554°C) and work-hardens quickly — relevant for jewelers working with the material.
What is palladium used for?
Catalytic converters account for the majority of global palladium demand — approximately 80% or more of annual supply. Palladium oxidizes carbon monoxide, hydrocarbons, and nitrogen oxides in gasoline engine exhaust systems. The rise of emissions regulations globally drove palladium prices from under $500/oz in 2016 to over $2,800/oz in 2022 before the market corrected. Electronics use palladium in multi-layer ceramic capacitors (MLCCs) used in smartphones and computers. Dentistry uses palladium alloys for dental crowns and bridges. Jewelry — palladium can be used in its pure form (950 palladium) for rings, settings, and other jewelry as a white metal alternative to platinum.
Palladium vs. platinum vs. white gold
Weight: Palladium (12 g/cm³) is much lighter than platinum (21.4 g/cm³); white gold (14k = ~13.2 g/cm³, 18k = ~15.2 g/cm³) sits between them. Price: Palladium spot has historically been close to platinum; both have been more expensive per gram than gold at various points — check current spot for accurate comparison. Allergy risk: Platinum and pure palladium are both naturally hypoallergenic; white gold may contain nickel (a common allergen) depending on the alloy formula. Maintenance: Platinum and palladium do not require plating; white gold requires periodic rhodium replating. Scratch behavior: All three metals scratch with use, but palladium and platinum develop a distinctive patina (scuffs redistribute metal rather than remove it) that many collectors prefer.
Why palladium is valuable
Palladium is primarily mined in Russia (approximately 40% of global supply) and South Africa (approximately 36%). Supply is inflexible — palladium is typically a byproduct of nickel and platinum mining and cannot be rapidly scaled. Demand from catalytic converter manufacturers is driven by global vehicle production and emissions standards. This supply-demand imbalance has created significant price volatility historically. Palladium prices peaked above $2,800/oz in early 2022 driven by supply concerns and sustained automotive demand, then declined as hybrid and EV adoption increased.
Palladium in jewelry: what buyers should know
Palladium jewelry is typically hallmarked as “950Pd” (95% pure palladium, 5% ruthenium or other PGM alloy). It is naturally white and does not require plating. It is lighter than platinum, which some buyers prefer for comfort in rings and bracelets. Work-hardening during wear means palladium rings can become slightly stiffer over time. Resizing is technically feasible but requires a jeweler experienced with palladium. Ask your jeweler to confirm their palladium experience before commissioning work.
How palladium and precious metals are valued
Palladium value is calculated the same way as other precious metals: weight × purity × current spot price. The spot price for palladium trades on the London Platinum and Palladium Market (LPPM) and major commodity exchanges. For jewelry, value may also include brand premiums, craftsmanship, and gemstones.

Frequently Asked Questions
What is palladium?
A rare platinum-group precious metal (Pd, atomic number 46) valued for industrial use in catalytic converters and for jewelry as a white metal alternative to platinum.
What is palladium used for?
Primarily catalytic converters (~80% of demand), followed by electronics, dentistry, and jewelry.
Is palladium better than platinum for jewelry?
Palladium is lighter and typically less expensive; platinum is denser and often considered more prestigious. Both are naturally hypoallergenic and do not require plating. Choice depends on budget, preference, and intended use.
Is palladium good for jewelry?
Yes — it is hypoallergenic, naturally white, durable, and does not require replating. Confirm your jeweler has palladium-specific experience for sizing and repairs.
Why is palladium so expensive?
Constrained supply (primarily from Russia and South Africa as a mining byproduct) combined with strong industrial demand from the automotive sector drives prices. Supply cannot be rapidly scaled.
