Dupe jewellery where to find ?

[juless77]

Anyone know of any websites I can find dupe jewellery please ?

What do you mean by dupe? Things like cubic zirconia and crystal instead of diamond, or fake Chanel?

Fake but not illegal a bit like Etsy sites ?

Do you mean counterfeit Tiffany , Chanel etc ?
My understanding is that if it copies a recognised design it will be illegal.
We have a local boutique selling fake Chanel brooches and I've no idea how they are getting away with it.
Or do you mean costume jewellery?
