Stainless Steel vs Plated Jewellery — What Actually Lasts
Most jewellery described as "gold" or "silver" isn't solid gold or silver. It's a base metal — usually brass, zinc alloy, or copper — with a thin coating applied on top. The coating is what you see. The base is what you're stuck with when the coating wears through.

Understanding this distinction changes how you buy jewellery and carry tools.
The three categories
Solid precious metal — actual gold, silver, or platinum all the way through. Expensive. Won't tarnish or wear through because there's nothing to wear through. The forever option if you can afford it.
Electroplated — base metal (usually brass or zinc) with a thin metal layer deposited electrically. Looks identical to solid metal initially. The plating is typically 0.5–2.5 microns thick. High-friction areas wear through first — clasps, chain links, pendant bails. Lifespan: weeks to months depending on wear frequency and body chemistry.
PVD-finished stainless steel — machined stainless steel base with a Physical Vapour Deposition coating. The finish bonds at the atomic level under vacuum. Much thicker and harder than electroplating. Stainless base means if the finish ever does wear at an edge, the base isn't reactive or visually jarring — it's just brushed steel.
Why PVD on stainless is the practical choice
For daily-wear pieces — pendants, bracelets, rings worn constantly — PVD-finished machined stainless steel is the durability sweet spot below solid precious metal. The reasons:
- machined stainless steel is hypoallergenic and non-reactive. Body chemistry, sweat, and water don't affect it.
- PVD finishes are 3–5x harder than electroplating. They resist scratching and wear at friction points.
- If the finish does wear at an edge eventually, the brushed stainless underneath isn't ugly. Electroplated pieces that wear show brass or copper — noticeably worse.
- Stainless holds up in water. Electroplated pieces should be removed before showering — the moisture accelerates delamination.
How to spot which category you're buying
Look for these terms in product listings:
- Signs it's PVD stainless: "machined stainless steel," "PVD finish," "IP coating" (Ion Plating, same process), explicit mention of machined stainless steel as the base material.
- Signs it's electroplated: "Gold-plated," "18k gold filled" (different from solid 18k), "rhodium-plated," any mention of brass, zinc alloy, or copper base material.
- Red flags: No mention of base material, "stainless look," price significantly below comparable solid-metal pieces with no explanation of construction.
For carry tools specifically
Carry tools — pendants, spoons, tools worn daily — take more friction than decorative jewellery. They contact pockets, bags, and other metal objects. The case for PVD stainless over electroplating is even stronger here. A powder spoon necklace that's in daily use for a year needs a finish that can handle it.
GoBlow uses machined stainless steel with PVD finishes across the entire product range — the same standard used in premium hardware and premium watchcases. It's the right material for something you carry every day.
