I haven't used it much. Color: Silver Inner diameter: Approximately 2cm It's silver, but the shadowed areas have a slight blackish tint (it's been like that since it was new). The size is likely more suitable for men. If you need the measurements, please ask. If you have any questions, please comment^^ #Medistore #medistore #accessories #ring #silveraccessories #silverring #men #designring #silver
