Is 999 gold good for a charm you wear daily?

No. 999 gold is close to pure and very soft, so it scratches and bends with daily knocks. Keep it for display or occasional wear, or set it in a protective mount.

Can I put it on a bracelet?

It can hang from a bracelet, but the soft metal and small size mean it is safer on a display or a chain worn rarely. Check the jump ring and attachment before wearing it.

Is it solid gold or plated?

It is described as 999 gold, which means fine gold rather than a plated base metal. Ask for the weight and any assay or certificate before buying.

Is this an official Harry Potter collectible?

The design is a chocolate frog, a Harry Potter motif, but nothing here confirms an official license. Treat it as a themed gold charm, not a certified collectible.

What should I check before buying?

Confirm the exact weight in grams, whether a certificate or assay card comes with it, and the return policy for gold items, since many sellers restrict returns on precious metal.
