The thing is if they are handmade in the uk you cannot expect the lower prices of big retailers with massive and established factories in China. I don't know how technically difficult those earrings are but UK made, artisan made are always 3x+ times the price of a Shein or Next equivalent.
I would not but them because my hair would tangle in them, I can just see it. I don't know their retailer but it reminded me of museum shops jewellery that have very expensive artsy pieces. They want a certain client where £180 is like £18 to them.
They look like they could be £12 or £320 depending on who is wearing them and how.
