What Is Gold Vermeil?
DEFINITION · FTC STANDARD · vs GOLD PLATING
Vermeil is jewelry that meets a special standard — a high-purity gold coating over a silver 925 base. Unlike ordinary gold plating, it's an honest design made to last.
- Vermeil = gold-coated jewelry meeting all three FTC standard conditions.
- Conditions: ① silver 925 base ② gold 10K+ ③ gold layer 2.5μm+.
- Structurally different from ordinary gold plating (0.5–1μm, brass/steel base).
- SMUK exceeds the standard: 18K and 3 microns. The base that touches skin is silver 925.
What Is Vermeil?
Definition
Vermeil (from the French) refers to gold-coated jewelry that meets a specific quality standard. Unlike plain "gold plating," a piece can only be called "vermeil" when all three conditions of the US FTC (Federal Trade Commission) standard are met.
The three FTC conditions:
- The base material is silver 925 (only high-quality material of 92.5%+ pure silver)
- The gold purity is 10K (41.7%) or higher (a minimum purity is required)
- The gold coating is 2.5 microns or thicker (several times ordinary gold plating)
Only when all three conditions are met can a piece be labeled "vermeil." If even one is missing, it's treated as ordinary "gold plating."
Standards by Country & SMUK's Spec
Standard
Vermeil cross-section — a thick gold layer over silver 925
Vermeil standards vary by country. The US FTC standard (2.5 microns+) is the most widely known, though details differ in some countries. Japan has no legal "vermeil" definition yet, but trustworthy brands reference the FTC standard.
| Item | FTC Standard | SMUK's Spec |
|---|---|---|
| Base material | Silver 925 or above | Silver 925 (92.5% pure silver) |
| Gold purity | 10K (41.7%) or higher | 18K (75%) — well above the standard |
| Coating thickness | 2.5 microns or more | 3 microns — above the standard |
SMUK references the FTC standard while adopting a higher spec. Gold purity is 18K, not the 10K minimum, and the coating is 3 microns, above the 2.5-micron standard — a design that doesn't compromise on quality where it's close to the skin.
Features of SMUK's Vermeil
Features
- Shower- and swim-friendly — the thick 18K coating and silver 925 base are designed for everyday contact with water
- Safe to wear 24/7 — since the part touching the skin is silver 925, allergy care is built in from the base material
- Allergy-conscious materials — no nickel or cobalt; a silver 925 base
- A thick finish made to last — the 3-micron 18K coating is several times more durable than ordinary gold plating
SMUK's vermeil is designed with "being wearable 24/7" as one of its standards. That said, environments with strong chemicals — seawater, hot springs, bleach — can affect the coating.
vs Ordinary Gold Plating
vs Gold Plating
Much of the gold-colored jewelry on the market is gold plating over a base of stainless steel or brass. It's easier on cost, but depending on the base material, metal-allergy risk can rise.
| Category | Ordinary Gold Plating | Vermeil (SMUK) |
|---|---|---|
| Base material | Stainless steel, brass, etc. | Silver 925 (pure silver) |
| Coating thickness | About 0.5–1 micron | 3 microns (above the standard) |
| Gold purity | No requirement (low purity OK) | 18K (75%) |
| Allergy care | Depends on base (nickel, etc.) | Cared for via silver 925 base |
| Durability | Thin, so peels easily | Thick — suited to long-term wear |
The base material against the skin, the coating thickness, the gold purity — none of these show in a piece's appearance, yet they're the most essential factors deciding whether it can be worn safely for a long time. SMUK keeps choosing specs that exceed, not just meet, the minimum standard.
However thick the coating, it can change little by little over time. Areas repeatedly touched by sweat, friction and cosmetics are especially prone to discoloration and wear. For long enjoyment, we recommend regular care.
Because the base is silver 925, even when the surface coating thins, what touches the skin is 92.5% silver. Metal-allergy care is designed in from the base material.
Jewelry made to last, for you. SMUK's gold vermeil is designed to blend into your everyday style while being something you can wear with confidence for a long time.
