upgrading stone without replacing setting

[vintagestones]

Hi all! I have a question that I was hoping I could get some advice on. My engagement ring has a 5mm moissanite center stone in a basket setting with two small diamonds on each side. My fiancé and I are in a much better financial position now than when he bought the ring nearly two years ago, so we're thinking of upgrading the center stone to a diamond. I would really love a vintage old mine cut or old European cut stone, and I do really like the setting so I would like to keep the same setting but just switch out the center stone. My question is, will I have to find a diamond with the same dimensions as the current stone, or can the basket setting accommodate a slightly larger stone, say +0.2-0.5mm in diameter? I'm going to a jeweler next weekend, but I'm impatient and wanted to see if anyone has any knowledge to share. Thanks!

It depends on the setting, but most settings dont have much wiggle room in terms of stone size (unless it's a solitaire in which case sometimes the head can be replaced). So maybe .2mm? But you would need to ask a jeweler. Can we see a pic in the meantime?

Thanks for responding! I figured the size can't be changed that much, but I'm hoping there's some flexibility so I don't have to find a new stone with the exact same dimensions. Here are some photos. Thanks again!
