Using virtuemart 1.1.8 and a custom template i made myself for my wifes jewellery website.
Your website looks quite good. It will have better look if you will make some additions. I suggest you to add header(as example you can make jQuery header slide-show using your top products). Also try to make logo for your jewerly store, it will help your visitors to remeber your online shop
It would be better if it can have the column line.
changed the template so have another look, you might like it
