Postage is combined:When you pay for all the gems together you only have to pay the postage for one item, the item with the most expensive postage.

Not all cz is the same, cut and quality vary a lot. It is important to choose good quality cubic zirconia for your jewellery, as the price of the stone is relatively cheap compared to the price of the precious metal and time taken to make the piece. The difference between a good and bad quality cz can only be a few pence, yet a bad or medium quality cz can make a good piece of jewellery, that has cost a lot of money and time to make, look cheap for the sake of saving a few pence on the cz.

So why would you not get the best quality cz? Just replacing a bad quality cz with a good one can make so much difference, a cheap looking ring can be transformed into a beautiful one just by replacing the stone. If you want beautiful jewellery, then you need quality gems.
