Trying to create a ring like in the pic.. Help please!

[AJM2021]

Hello all,

Since I've got some raw gem stones and would like to make a ring like this in those pics,
been searching for Blank Claw Ring (BTW is the name correct??)



Do you know reliable UK seller that sells blank ring like in the pic?
Preferably UK seller as I'm worried about Import duty but... overseas seller is fine as long as they are reliable or you've used before.

I've searched on eBay, Etsy but have not really found the item/seller unless I am typing the keyword wrong?


-- I prefer just 4 claws
--18k Gold 9K Cold, or 925 Silver



Thanks in advance
