Congrats on your lovely new piece! Mine's quite small, it's only 0.07ct. Thanks to the thick bezel, it measures 5mm across, similar to a 0.18ct with the thin bezel. Thick bezels are only on the SS and RG versions, and on RG below 0.18ct.
Here's a faraway shot for perspective:
But then when it catches the light, it REALLY shines!

I'm sure yours is even more spectacular!
I hope you're able to get used to the poke and enjoy it, otherwise try the 0.17ct in RG with the thick bezel?
I've been wearing mine every day and just love it, in fact I love it so much I'm going to buy my mom the exact same one when she comes to visit!
