I'm a jeweller and I have sold a few in gold and white gold the past months.
Only to people who want to have a lot of hidden valuables on them if ever they would need money.
But this kind of jewelry is really not cost effective for consumers to buy. It costs me about 400€ in gold to make 1 stay, and I sell 2 for 2000€.
The work is ridiculous, you can buy gold sheet yourself. Sawing them and buffing them will take 15 minutes.
