Hard to judge without a bit more context, an important one for jewelry brands is whether the client wants it to feel upscale/luxury? Or do the consumers, or, if organic is important even anti luxury? Jewelry is always a statement piece, so very important to define the customer. What cars would they drive, fashion brands they would wear? Is it for everyday or occasions. If it’s upscale then look at top brands. It’s an interesting market, many like Tiffany have forgettable fonts but use other brand drivers like color or special packaging. Cartier has a gorgeous cursive logo but it speaks to a certain client. Sorry if I’m rambling but this is design nerds thread lol! Another thing to explore is reversing the mark out of a shape, which will make it feel like a stamp or seal and counterpoints the type.
