WTB Any Aussie members looking to sell a round brilliant solitaire ring?

Before I take the leap and purchase my ACA solitaire from Whiteflash I thought I'd try my luck and see if there are any Aussies here who are thinking of selling a round brilliant solitaire. Ideally I would want an ACA 0.7-0.9 carat (or larger depending on price) but I'm also open to other really well cut RBs as well. White gold would be my first choice, platinum would be second. Not really into yellow gold but still open to considering it if I love the setting.

Only reason Im looking for Australian sellers is the GST I need to pay on purchases over $1000 entering the country, and the whole customs process seems to be a bit of a pain!
