Where to buy birthstone earrings for pre-teens

[1stMrsF]

I want to buy some birthstone ear studs for DHs goddaughter and her sister (13 and 9) - can anyone suggest a good place to buy (online)?

thanks

Argos used to do them.

Yes Argos

I think Avon used to do them as well. 20 years ago anyway.

Thank you, I hadn't thought about Argos as an online shop. I will have a look.
