WHOA - that's gorgeous! maybe you can put a few coats of a matte finish on to protect from scratches?
i've only tried the fimo gloss varnish (they may be better brands which dont do this) but i've found that once scratched the varnish looks worse than the polymerclay
the varnish starts to peel off at the site of the scratch and adding another coat of varnish over the top leaves 'tide' marks unless you varnish the entire thing again
small scratches arnt too noticeable but a big gouge or deep scratch is. very. the bangle style bracelets seem more prone to scratches (i guess because they stick out more) but unless its a big one the scratches them selves dont seem as noticeable on that style of bangle, the cuff bracelets dont seem to get scratched as easily but because the visible surface is much larger the marks seem more noticeable.
