Three parts to read separately
- The stone
Moissanite is silicon carbide. It is a different gemstone from natural or laboratory-grown diamond.
- The base
S925 denotes sterling silver with a silver fineness of 925 parts per thousand: 92.5% silver.
- The surface
18K gold plating describes a surface layer over the silver base. It does not mean the whole piece is solid 18K gold. White gold is a gold alloy, different from platinum.
The finish, from base to surface
These are FUGUI’s stated finishing sequences for the relevant S925 pieces. Follow the finish identified for your product and selected color. The specification is manufacturer-supplied; it is not an independent test report for your item.
Swipe or scroll the table sideways if needed. All measurements keep their stated units.
| Order | Material | Metal-plating thickness |
|---|---|---|
| 1 | S925 sterling silver base | — |
| 2 | Silver plating | 3 µm |
| 3 | Palladium plating | 0.03 µm |
| 4 | Rhodium plating | 0.03 µm |
| 5 | 18K white gold plating | 0.03 µm |

| Order | Material | Metal-plating thickness |
|---|---|---|
| 1 | S925 sterling silver base | — |
| 2 | Silver plating | 3 µm |
| 3 | Palladium plating | 0.03 µm |
| 4 | 18K gold plating | 0.03 µm |
| 5 | Protective electrophoretic lacquer (e-coating) | — |
A micrometer (µm) describes very thin layers. E-coating is an additional protective lacquer; the thickness column describes metal-plating layers. A dash does not specify a thickness.
Back to contents ↑Silver and plated finishes need care
Sterling silver can tarnish, and plated surfaces can wear with abrasion and chemicals. The rate depends on use and care. Remove jewelry before bathing, swimming, exercise or household cleaning, and put it on after perfume and lotions have dried.
Read the jewelry-care guide for gentle cleaning and storage.
Back to contents ↑Know which document you are requesting
GRA moissanite grading documentation is included at no extra charge; one report is included per pair of earrings. It describes the moissanite. Sample report images show a format and are not reports already issued for your order.
S925 silver material testing is a separate, optional paid service, available on request. Fees and turnaround time are quoted separately. Ask about a product and option before arranging a test.
