Hi Marta,
Glad to have you on board!
Yes, we have a lot more jewelry on the site than any other products, but that doesn't mean your products will get lost. Our new products sub-categories allow people to find very specific products. So if you have products that match their replacement criteria, they'll find them!
Also, all jewelry pages atract jewelry seekers. So once people arrive on the site, there is a chance they'll explore other jewelry pages. Hope this helps.
