Palladium (Pd) is a chemical element that plays two different roles in jewelry: on its own, as a standalone metal, and inside gold, as the alloying metal behind "palladium white gold," which is never a pure metal by itself. Both leave a bright white finish at the counter, yet they diverge on density, hardness, purity marking and price once a scale or a loupe gets involved. This page compares standalone palladium jewelry with palladium white gold across those measures, then prices both against today's palladium market.
Palladium vs White Gold at a Glance#
Standalone palladium jewelry and palladium-alloyed white gold differ across density, hardness, melting point and purity marks, even though palladium sits inside both. Palladium belongs to a six-metal family with its own comparison hub, platinum group metals compared, but the table below isolates only the two forms a buyer is most likely to confuse at the jewelry counter.
| Property | Standalone palladium | 18K white gold | 14K white gold |
|---|---|---|---|
| Density (g/cm3, 20°C) | 12.007 | ~14.7-16.9 (alloy-dependent) | ~12.6-14.0 (alloy-dependent) |
| Hardness | Mohs 4.75; Vickers 400-600 MPa annealed | Alloy-dependent: nickel-alloyed harder, palladium-alloyed softer | Alloy-dependent: nickel-alloyed harder, palladium-alloyed softer |
| Melting point | 1,554.9°C (1,828.05 K) | Varies by alloy; base gold melts at 1,064.18°C | Varies by alloy; base gold melts at 1,064.18°C |
| Fineness mark | UK: 500, 950 or 999 | 750 (18 of 24 parts gold) | 583/585 (14 of 24 parts gold) |

What Is Palladium White Gold?#
Palladium white gold is an 18K or 14K gold alloy that uses palladium, instead of nickel, as its whitening metal, a substitution jewelers have made since 1939. Both karats sit on the same gold scale, 75.0% gold at 18K and 58.5% gold at 14K, with palladium filling part of the remaining alloy alongside silver, zinc or copper depending on the manufacturer.
Readers arriving here from a broader search often want a three-way answer among platinum, white gold and palladium, but this page covers only the palladium-versus-white-gold half; the platinum leg is answered on platinum vs white gold and the palladium-versus-platinum leg on platinum vs palladium.
Palladium White Gold vs Nickel White Gold#
Nickel white gold is harder, whiter and cheaper; palladium white gold is softer, grayer, more expensive and non-allergenic, the two families jewelers mean whenever they say "white gold." Both alloys start from the same 75.0% (18K) or 58.5% (14K) gold base; only the whitening metal, and the properties that come with it, differ.
| Attribute | Nickel white gold | Palladium white gold |
|---|---|---|
| Color | Whiter, cooler tone | Slightly grayer tone |
| Hardness | Harder | Softer |
| Allergen risk | Contains nickel, a common contact allergen | Non-allergenic |
| Plating need | Usually rhodium-plated to hide its warmer tone | Needs no rhodium plating |
| Relative cost | Cheaper | More expensive |
Why Palladium White Gold Needs No Rhodium Plating#
Palladium white gold needs no rhodium plating because palladium alloys to a naturally white color, while nickel white gold is usually plated to hide its warmer tone. Rhodium itself is a separate platinum group metal, electroplated onto white gold and sometimes platinum purely for a bright, reflective surface; that thin layer wears away with ordinary use, which is why nickel white gold eventually needs replating and palladium white gold does not.
Palladium vs White Gold: Density, Hardness and Purity#
Pure palladium is 12.007 g/cm³, denser than 18K white gold's 14.7-16.9 g/cm³ range and 14K white gold's 12.6-14.0 g/cm³ range, both of which vary by the specific alloy. That density gap means a standalone palladium ring feels noticeably heavier than a white gold ring of the same design, before either metal's fineness enters the comparison. The full density, hardness, melting point and fineness figures for all three forms are in the table above.
Palladium's own hardness, Mohs 4.75 with a Vickers figure of 400 to 600 MPa annealed, sits between the two white gold families: harder than palladium-alloyed white gold and softer than nickel-alloyed white gold, since jewelry-grade alloys are always harder than either metal's pure annealed form once other elements are mixed in.
How to Tell If Jewelry Is Palladium#
Jewelers identify standalone palladium jewelry by its hallmark: UK law permits 500, 950 and 999 palladium fineness marks, with 500 as the legal minimum. Palladium hallmarking became compulsory in the UK on 1 January 2010, so pieces sold there after that date carry one of the three marks by law.
- Look for a struck fineness mark reading 500, 950 or 999.
- Check for an assay office mark alongside the fineness stamp.
- Confirm the piece is not stamped 14K or 18K, marks that belong to gold alloys, including palladium white gold, rather than to standalone palladium.
Palladium vs White Gold: Which Costs More?#
Palladium traded at $1,354.00 per troy ounce on Kitco's spot series, 5 August 2026, while white gold's precious-metal value comes from its gold content, 58.5% at 14K or 75.0% at 18K, priced against the separate gold market on the same date. The two metals never share one price line: a buyer comparing them prices palladium content and gold content separately, then adds each alloy's fabrication cost and, for white gold, its recurring rhodium plating cost.
Today's palladium price today tracks that first number in troy ounces, grams and kilograms, updated through the trading day rather than fixed to a single date.
Palladium vs White Gold: Allergies and Long-Term Wear#
The allergy risk in white gold jewelry comes from nickel, not gold, which is why the EU restricts nickel release from jewelry under REACH Annex XVII, entry 27, and why palladium white gold avoids the issue entirely. Nickel contact allergy is among the most common contact allergies in the general population, and it is the nickel in nickel white gold, not the gold itself, that triggers a reaction in sensitive wearers.
Rhodium plating offers only a temporary barrier against that nickel: a typical plating layer runs 0.75 to 1.25 micrometers thick, lasts 1 to 3 years of wear, and costs $35 to $150 to reapply in the US once it wears through. Palladium white gold needs none of that maintenance, since it carries no nickel and no plating layer to begin with.
Compare Palladium and White Gold at Today's Price#
Palladium's price and palladium white gold's gold content move independently, so buyers compare them against today's separate metal prices rather than one combined figure. Checking both prices on the same day is the only way to compare a standalone palladium piece with a palladium white gold piece on equal terms.

Palladium vs White Gold FAQ#
Is palladium worth more than white gold?#
Whether palladium is worth more than a specific white gold piece depends on the piece's gold content and weight, not a single price comparison, since white gold is a diluted alloy and the palladium price quoted here is for pure metal. A heavy 18K white gold ring can hold more precious-metal value than a light standalone palladium piece even while palladium and gold trade at different prices per ounce.
How can you tell if jewelry is palladium?#
Jewelry is identified as palladium by its fineness hallmark (500, 950 or 999 in the UK); a home acid or magnet test is not a method this knowledge base has sourced data to recommend. The hallmark, not a home test, is the reliable identifier.
Why might someone avoid white gold?#
Some buyers avoid nickel white gold specifically because of nickel contact allergy, one of the most common contact allergies, not because of the gold in the alloy. Switching to palladium white gold removes that specific risk while keeping the same white color and karat system.
What are palladium's downsides as a jewelry metal?#
Standalone palladium jewelry's main downside is market thinness: global palladium jewelry demand has fallen to roughly 0.8% of total palladium demand, so retail selection and resale channels are narrower than for gold or platinum. Johnson Matthey puts 2025 palladium jewelry demand at 2.5 tonnes (83 koz), down from a 2005 Chinese peak of 37 tonnes.
What is palladium's symbol, atomic number and CAS number?#
Palladium has the symbol Pd, atomic number 46 and CAS number 7440-05-3, with a density of 12.007 g/cm³ at 20°C. Its full properties, uses and identity data beyond this comparison are covered on palladium (Pd), element 46.
