I went in today for a look, but they didn't have it in the Perth store. They also told me they are not going to get it in the Perth store but that they would try to order it in for me - no promises. Apparently it's only available in the Eastern States. That's a bit strange considering it's available to buy from the website. I wouldn't order it from the website though because being such a big/wide ring it's so hard to guess the size. I just had to do the best I could to guess from trying on other big rings in the store today!
So anyway fingers crossed. If I do get it, I'll be posting pics here for sure!
