How to figure out carats of a Cartier Trinity ring?

[2v2hunters]

Hi all, I recently acquired a pre-loved Cartier Trinity. It looks like this one below. Would you happen to know how I can figure out how many carats total are the stones? Thanks so much in advance!

I have this ring in a size 52, which Cartier says contains 1.6 carats.

Hope this helps.
