Lovely
Ring Size: 6.25
The only word for this ring is "lovely." It took a long time to get to me as I ordered it January 30, 2026 and it arrived the third week of February but to be honest, it was worth waiting for.

Perfect fit, both literally and figuratively.
Perfect fit (after I got my ring size correct!) and looks great next to my large engagement ring. Doesn't take away from the engagement ring, but enhances it with the simple, but delicate two-tone white and yellow gold design,
