Engagement rings

[millymollymomoooo]

YIPPIE! My other half proposed the other day, I'm over the moon, super happpppy!

But, he used my mothers ring, which is beautiful and so lovely, but it was only a temp until we get back home and I can choose one I like. Where do I start? Are there any websites? I want something vintage/classic. Oh, and we live in Sydney! So any recommendations for places there? Thanks!
