Sterling Silver vs. Brass-and-Plate: What's Actually Underneath Your Jewelry

"Gold plated" tells you almost nothing on its own. It doesn't tell you what's underneath the plating, how thick the plating is, or whether the stones set into the piece are glued in or actually set. Those three things are the real difference between jewelry that holds up and jewelry that doesn't — and they're rarely on the product page. Here's what to actually look for, using our own Southwest collection and a couple of well-known brands as reference points.

What's actually underneath the plating

"Plated" jewelry is a thin layer of gold (or rose gold, or rhodium) over a base metal. That base metal is the part that determines how the piece ages, and it's usually one of two things:

• Brass or another base-metal alloy. Cheaper to produce, and the reason a lot of affordable plated jewelry eventually discolors, "brasses" through at the edges, or turns skin green — the plating is the only barrier between your skin and the base metal, and plating wears with everyday contact.
• Sterling silver (92.5% pure silver). A genuine precious-metal alloy. Plating still wears the same way over time, but the metal underneath is itself a jewelry-grade metal rather than a coated base alloy — which is why sterling-silver-based pieces are generally categorized as demi-fine rather than costume jewelry.

The catch: you usually can't tell which one you're getting just by looking, and "gold plated" or "gold vermeil" on a product page doesn't specify the base metal by itself (vermeil is a legally regulated term in the US requiring a sterling silver base and a minimum gold thickness — but plain "gold plated" carries no such requirement and can be layered over anything).

What we found when we checked a few popular brands

We got curious how this actually breaks down across the brands people compare us to, so we looked at what each brand states about its own materials:

• Gorjana states in its own FAQ that its jewelry is made from a mix of brass and sterling silver, plated in options including gold vermeil, with gemstones concentrated in a separate "Fine" tier rather than their everyday fashion line.
• Mejuri states its jewelry is sterling-silver-forward (925, 92.5% pure silver), with vermeil (a 2.5-micron gold layer, by their stated spec) and solid 14k/10k gold options; brass is not listed among their stated base metals.
• Sugar Bean: every piece in our Sterling collection is disclosed on its own product page as sterling silver with 18k gold, rose gold, or white rhodium plating — no brass base, on any piece, at any price point.

None of this makes one brand "better" across the board — brass-based jewelry has its place, especially at a lower price point, and plenty of people replace fashion jewelry often enough that plating wear isn't a dealbreaker. But if longevity matters to you, the base metal is the single most useful thing to check, and it's usually one search away on any brand's own materials or FAQ page.

Hand-set stones vs. glued stones

The other detail that rarely makes it onto a product page: how the stones are attached. Mass-produced stone-set jewelry very often uses glue — the stone sits in a shallow setting and is adhered rather than mechanically secured, which is faster and cheaper to produce but means the stone can loosen or fall out with wear over time. Hand-setting — placing each stone individually into prongs or a pavé setting and securing it mechanically — is slower and more labor-intensive, which is exactly why it's uncommon at accessible price points. It's also why a lot of "sparkle" jewelry skips it in favor of smooth, stone-free designs, or uses glued accents instead.

Every stone we set, including the cubic zirconia in our Southwest collection's pavé pieces and the genuine lab-grown diamonds and green spinel in our palm tree pieces, is hand-set. We think that's worth knowing whether or not you buy from us — it's a reasonable question to ask about any stone-set piece you're considering.

How to check any piece of jewelry yourself

• Search "[brand] materials" or "[brand] FAQ." Most brands disclose base metal somewhere, even if it's not on the product page itself — Gorjana and Mejuri both do, for example.
• Look for "vermeil" specifically if you want a sterling silver guarantee. It's a regulated term in the US; plain "gold plated" is not, and can mean gold over anything.
• Check the stone-setting language. "Set with," "prong-set," or "pavé-set" generally implies a mechanical setting. "Adorned with" or no description at all is worth a closer look, or a question to customer service.
• Ask about plating thickness if it's not listed. A thicker plating layer (measured in microns) wears more slowly. Brands that are confident in their plating usually state the number.

FAQ

Is brass-based jewelry bad?

Not inherently — it's a reasonable choice at a lower price point, and plenty of people are happy replacing fashion jewelry every year or two. It's just a different category than sterling-silver-based demi-fine jewelry, and the two are often priced similarly enough that it's worth knowing which one you're buying.

What's the difference between "gold plated" and "gold vermeil"?

Gold vermeil is a legally regulated term in the US requiring a sterling silver base and a minimum gold thickness. Plain "gold plated" has no such requirement and can be layered over any base metal, including brass, at any thickness.

Does hand-set mean the stones will never fall out?

No setting is completely failure-proof with enough wear and impact, but a mechanically hand-set stone is generally more secure over time than a glued one, which can loosen as the adhesive breaks down.

Is Sugar Bean jewelry sterling silver all the way through, or just plated?

The base metal itself is sterling silver (92.5% pure silver) on every piece in our Sterling collection. The gold, rose gold, or white rhodium color is a plating layer on top of that sterling silver base — not a coating over a different base metal.
