WTB: white metal setting for 6.1mm round stone <$500

[SMC]

I'm looking for a white metal setting for my 6.15mm 0.91ct round parti blue-green Montana sapphire. I'd prefer it not look like an e-ring (so no plain solitaire settings). Ideally something that looks vintage, but I'm really open to ideas. Need something that can be sized to a 6.

I don't really want to pay more than $500, but if there's an exceptional setting in that price range, I'd definitely consider it.

I was going to buy this setting from jewelryhoo, but I wanted to check to see if anyone has anything preloved first.

Thanks!
