What is the perfect size for diamond studs?

Hi,

I'm looking to purchase diamond studs for an upcoming birthday and I'm wondering what your thoughts are for the best size? I would be wearing the earrings for everyday use and special events.

I'm trying to decide between 2 CTW or 2.4 CTW. Is it worth spending a bit more for slightly larger diamonds?
Please help.

Thanks!

I didn't find the right solution from the Internet.
