What Determines Jewellery Prices?

A ¥3,000 Earring vs a ¥8,000 One — Where's the Difference?
METAL · PLATING · STONE · CRAFTSMANSHIP

They can look almost identical, yet cost more than double. It's a question everyone pauses on. This isn't about "expensive = good" — the price gap has clear reasons that are hard to see from the outside. Let's break down what's inside the price, through four lenses: metal, plating, stone and craftsmanship.
- Metal: common metal like brass, or a precious metal like silver 925 — the material cost differs by an order of magnitude.
- Plating: thickness and "what's underneath" decide its life. Over silver 925, even worn plating sits on precious metal.
- Stone: three tiers — glass, cubic zirconia, natural stone. And natural stones have grades too.
- Craftsmanship: setting, posts, chain — the price lives where the photo doesn't show.
Metal — The Base Is Where Price Begins
Base Metal
The base metal is broadly either common metal like brass or zinc alloy, or a precious metal like silver 925. Silver trades on international markets as a precious metal, with a large gap in material price from brass. For the same design, silver 925 costs several times more in material.
Bigger than price is the relationship with the skin. Silver 925 is known as a low-allergy material, while cheap alloys may contain nickel and the like. One reason low-priced pieces are coated in thick plating is to keep the base metal from touching the skin — which is why skin trouble often appears after the plating wears off.
Surgical steel is also an excellent industrial material — tarnish- and allergy-resistant — but it is not a precious metal, and its raw material price is in a different league from silver. Yet it's sometimes sold at the same price as precious-metal jewelry. Choosing for design or brand is lovely. But knowing how much of that price the material accounts for changes the meaning of the choice entirely.
Plating — You're Buying "Time Until It Wears"
Plating Quality
One thing that decides a plated piece's life is coating thickness. The flash plating common in fast fashion is under 0.5 microns — so thin the color can fade in weeks to months. For reference, the US FTC standard for gold vermeil is a gold layer of 2.5 microns or more — several times the thickness, which translates into "how long the shine lasts."
Just as important is "what's under the plating." Plating over brass ends when it wears through. But rhodium, 18K or 14K plating over silver 925 sits on precious metal even as the coating thins. Two "plated products" that look the same can be structurally entirely different.
Rhodium in particular is a rare platinum-group metal — sometimes trading above the price of gold. Hard, tarnish-resistant, and keeps silver's shine for long. It's the opposite of the "plating = cheap" image — a luxurious coating.
Stones — Glass, Zirconia, and Natural Stone
Stones
Stones fall into three groups: the cheapest glass or resin imitation; cubic zirconia, a man-made stone with excellent hardness, shine and consistent quality; and natural stone, where no two are alike.
Even within natural stones, quality varies greatly. The same opal can cost many times more depending on the vividness of its play-of-color, transparency, and freedom from flaws. And as covered before, stones treated by dyeing or doublet-bonding are worth less than untreated ones. "Uses natural stone" alone tells you nothing about quality — whether the type and any treatment are disclosed is the reliable signal.
Hidden Craftsmanship — Setting, Post, Chain
Craftsmanship
The last difference is where the product photo barely shows. First, the setting. What matters is less "which method" than whether the right method for the stone is done carefully. Faceted stones suit prong or bezel settings; pearls and flat-based stones suit adhesive setting (even the world's fine jewelry sets pearls with adhesive). Trouble comes not from the method but from rushed, cost-cut work. A wobbly stone or excess glue reveals the maker's care — or lack of it.
For earrings, the post material matters. Even with a beautiful body, the post alone is often a cheap alloy. The part that touches the skin most deeply is exactly where you want to check the material. For necklaces, chain quality also affects price — the clasp, the evenness of the links, resistance to breaking. Whether the chain's material and origin are disclosed, as with Italian silver chain, is another measure of a maker's honesty.

What's Inside SMUK's Prices
SMUK Standard
SMUK's jewelry uses silver 925 as the base, with reliable plating finishes — rhodium, 18K gold, 14K white gold. Stones are selected natural stones, with type and material stated on each product page. Our pieces are designed nickel-free and lead-free, with metal-allergy care in mind.
What we aim for isn't to be the cheapest. It's to never betray the promise of "this quality, at this price," whenever you buy. If anything about the materials concerns you, please feel free to ask.
Knowing what's inside the price is the first step to choosing well. May that eye help you choose the piece that's right for you.
