Mine are 5 carat total weight and I adore them! Why don’t you wear yours?I have two sets of inside-out diamond hoops. The larger pair is 3 TCW (so 1.5 each ear) and they are probably one of the least worn items in my jewelry box. The others are huggies and I wear them often, more than my studs.
I personally would go to try on the Tiffany necklace again before deciding. I'm always surprised by the color tones of their golds.
