I originally had 1.04 ctw that I used for side stones in a 3 stone ring (Vatche royal Crown 3 stone). Then I got 1.52 ctw WF ACAs that I wore for about 5 mos and decided to trade up to the current pair. I am very happy with this size and since I wear them 24/7 I think this is as large as I will go (not to mention that my budget is blown to pieces!)
