im usually a size 5.5-6 US and i bought mine size 49 on my cartier wide trinity ring. size 50 is a better fit but i live in a relatively cold country and my skin shrinks plus the pandemic which means i have to wash my hands more often so i dont want my rings to wiggle around thats why i sized down. hope it helps ✌️
For me, I got a trinity size 50 but my wedding band size is 48, also from Cartier. The trinity actually doesn't fit my ring finger so I wear it on my pinky for now. The sizing is weird. I heard from others that I should size down from my normal ring size but it was opposite for me.
thanks so much for sharing. Yea I agree... with the Trinity ring, it's best to try it in the store if you can. I find that in the summer months when my fingers swell up with the heat, my trinity fits much tighter too... at least it still looks really chic on your pinky finger🥰xoxox
