I am hoping that the copywriting was a favour, please tell me you didnt pay for that to be written.
Could I also add a few more things for you to look at when pushing the site.
I know ecommerce sites are a little more difficult to get to the top of google.
And I will open a slight can of worms especially as I am not a SEO specialist but here goes.
Meta Data...debates if this works or not but it wont harm having meta data in your site,
this is jo's meta data
<metaname="description" content="Unique hand crafted tiaras and jewellery. Stunning range of Wedding Jewellery, Bridal Tiaras and evening jewellery at affordable prices.

<metaname="description" content="Unique wedding Jewellery from Crystal Jewels. Each design comes in a range of colours and styles and is made exclusively for you" />
<metaname="keywords" content="crystal jewels" />
A bit of a difference.
I would also suggest that if you are getting peoples info like email addess contact details you need to have a terms of use and defo a privacy page to let the consumer know what you are doing with their information.
I would then look at Jo's site and again look at her sitemap and compare it to yours and take bits out that you like and think are relevant to your market. Looking at your sitemap and Jo's it is "being brutally honest" poles apart she has tenfold the amount of pages you have. Again one thing that makes yahoogle happy is content content content. That is updated on a regular basis.
I think the first and most important thing you should do is either market it for "Handmade Jewellery" or "Wedding Jewellery"
Like I think I stated earlier I think you will have a harder time getting to the top of "Handmade Jewellery" than you would "Wedding Jewellery".
But again that would be for an SEO specialist to say.
Oh and one final word of advice if you are going down an SEO route and you pick up the phone to a SEO company, if you hear the sentence.."We work very closely with Google" giggle and put the phone down and move on to the next. They are full of Rubbish.
