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.

Unremarkable
Ring Size: 7
The photos were expertly taken for sure. The ring is nice, decent quality, 14k as advertised but the design and stones are less than exciting. It’s nice, that’s about the best I can give it.
