Hi Sazkat
A few things that I noticed.
The image on your homepage is very over dominating and as it's not a high resolution image it's not really a massive selling point for you. What would be better would be a small rotating selection of top selling items, or specials for the month.
Your logo banner does not return you to the homepage, you have to click on home, which is also giving random errors. It's fairly conventional to have your logo clickable and for that to return customers to the homepage so it would be a good thing to accomodate.
Everything from delivery downwards should be on your top navigation bar not your left, this is best left as your products particularly as you have a long category list.
Free postage on orders over £1000 is really high, and not really much of an incentive, consider setting it at £50 or £100, or something much lower, your average customer is not going to spend £1000 online so its just not going to be a selling point for them.
Personally I don't like the colour scheme at all, but thats my personal opinion but I find it a bit dull, the site doesn't standout, I think a better, brighter, more curvy template would be a better choice.
Your navigation bar is cutting off the end of the words on the real orchid jewellery & terms and conditions, which makes the site look less professional.
It takes a lot of click to actually buy an item, if I click on Buy Now, I can't actually buy now at all, I still have to add it to the cart and then I still have to checkout and then when I get there I'm immediately irritated to find the dreaded register first section. Customers do not want to register first in order to buy an item, they want to add to a basket and then checkout, this should all be streamlined into one process, the more clicks it takes a customer to purchase the more chance you have that they will just abandon their shopping basket and go elsewhere. Customer registration should be taken as part of them giving their delivery and invoice details in order to make it smoother. Yes you want them to be able to login and see their orders and to have that detail captured for newsletters etc, but that should not require prior registration.
Even at registration stage I can see that I still have 5 more stages to go before I have paid and can leave the site, and it's taken 3 click just to get to the registration, I would have most likely left the site by now unless I really really wanted the item.
Hotmail address as other have said is a huge no no, I would not buy jewellery from a site which only uses a hotmail address and which has no postal address. Also it is now a legal requirement to put your company registration and address details on your site and there is a sweep of internet retailers due to be carried out starting form this month to check that all the Distance Selling Act regulations are being complied with & correct terms and conditions are being displayed which includes a no quibble returns policy.
