Hi there!
I'm going to be honest from the get-go. I'm a versatile writer, and I know how to sell to a target market consisting of real people and not just soulless demographics. I've done a little fashion-related work, and as a woman, I think I know what I'm doing when it comes to fashion and accessories.
My final "qualifications" would include the fact that my partner is a jeweler, so I've learned a lot by listening to him talk shop. I've also done jewelry product descriptions for the occasional website and should be able to hunt down some examples.
Would I be the writer you need for your blurb? That's up to you to decide, but I should mention the fact that I'm a writer - no more, and no less. Trying to do more landed me the rotten review at the top of my profile page, but if you dig a little deeper, you'll find that I did really well before that.
So, much as I hate to add caveats when I'm selling myself as a writer, I will mention my limitations. I figure it's a bit like the "choking hazard" tag you get on a variety of toys and household products that nobody in their right mind would put in their mouth. It doesn't hurt to state the obvious.
Thanks for considering my bid :)
Andrea
