This is a size 11 peridot ring with a K10WG hallmark. The white gold band is approximately 5mm wide, and the peridot is also about 5mm x 5mm. It has a substantial feel and presence, but the clean design means it won't snag on anything, and you can wear it all the time. I've worn it quite a bit, so there are quite a few scratches on the white gold, but they wouldn't show up in the photos. Also, as shown in the second photo, there is a hallmark, but it didn't photograph clearly either. I have confirmed the hallmark with a loupe. I will send the ring itself via Nekopos (a Japanese postal service). The case is not included. It's an older piece, so it uses a generous amount of metal, but it does have scratches. The peridot has a refreshing color. According to my unreliable kitchen scale, it weighs 4g. I hope someone will like it. #Peridot #10K #Size11 #WhiteGold #Ring
