I agree, I'll try it.You should sell your jewelry on TikTok!
Make short, fun videos showing how you make the jewelry. People love watching that kind of stuff. You could even do live streams to answer questions and show off your latest pieces.
Would it be an infringement if the same design is displayed on TikTok or Instagram?How well known is your brand? For expensive jewelry you need to spend a lot on your branding. People just don't trust a newer brand that easily.
Try low ticket products. Create same designs but with cheaper material. Like stainless steel with pvd gold plating or other metals.
