How to Identify Rose Gold
Rose Gold is usually rose gold, pink gold, and coppery gold with a metallic luster and is opaque. It has a Mohs hardness of 3. A copper coin (Mohs 3.5) scratches it, but a fingernail does not. Its streak is rose-gold metallic. It is most often confused with Bronze, Gold, and Copper; the tests below separate them.
Rose Gold identification checklist
| Color | Rose gold, Pink gold, Coppery gold, Warm pink | Look at a clean, dry surface in daylight. Color zoning, banding or spots are as diagnostic as the hue. |
|---|---|---|
| Luster | Metallic | Turn it under a lamp: a true metallic shine reflects like polished metal and stays opaque at thin edges. |
| Transparency | Opaque | Hold a thin edge up to a bright light and note whether light passes through. |
| Mohs hardness | 3 | A copper coin (Mohs 3.5) scratches it, but a fingernail does not. |
| Streak | Rose-gold metallic | Drag a corner across unglazed porcelain (the back of a bathroom tile) and check the powder color. |
| Cleavage | None | |
| Fracture | Ductile to uneven | |
| Specific gravity | 15 | Very heavy, metallic heft (specific gravity about 15). |
