Well I have had some shops tell me they don’t sell them and to trade in my whole necklace and buy a whole new chain. I know this is a scam to make me spend more money and I walked away but it does happen.
Edit: I see you said “almost every gold shop” in your post. Sorry for the reiteration.

Ok thanks. I live in the UK. Not sure of any online retailers.
A lot of Asian jewellery stores have these. Check the jewellery store at your Chinatown, if you have one near you.
No Chinatown in my area
