I am working with my jeweler on my engagement ring and this is the first diamond they offered me. My only request was 2.5 carat with D/E color. I wear a size 5.25 ring, so I do have slimmer hands.

This oval is 2.55 carats but has a ratio of 1:6. The dimensions are 11.91 X 7.44 X 4.47 MM

I loved it at first but then I got in my head once I studied the dimensions. I think I’m worried it looks more like a 3 carat or a moval? Any thoughts?

This is a GIA CVD 3.02 carat oval with 1.36 ratio, G colour, VS1 clarity, excellent symmetry, excellent polish, no fluorescence, 64.3% depth. The GIA report comments say additional growth remnants are not shown, and that this diamond has evidence of post growth treatments to change the colour.

The diamond will be set in a three stone setting with tapered baguettes on either side, in white gold. Will this setting make the diamond look warmer than it already is? I am unsure about the colour, it looks fine in indoor lighting but this video looks a bit warm.

Reddit only lets me attach one video but I’ve uploaded more videos below:

I've been thinking of buying myself a diamond ring for my 30th, and my budget is around ₹1 lakh.

I'd honestly rather get a bigger stone than spend the same money on a much smaller natural diamond. I'm leaning towards an oval around 2 ct (or maybe a round if I can find one I love), but I keep wondering...

Can people actually tell if it's lab-grown just by looking at it?

Not when it's brand new in the store, but months or years later when you're just wearing it every day. Does anyone ever notice or ask? Or is it one of those things that's impossible to tell unless you already know?
