Anyone know about ring sizes?

[Reiningitin]

Hoping someone can help me. Is this a ring size (attached pic.) If so what would next size up be?

Order a ring sizer off amazon or ebay

'The diamond store' has an app where uoi can measure your ring and it will tell you what size it is. They you can see the next size up.

I used it to measure dps ring this week.

Oh great will try the diamond store app. Did think about ordering a ring sizer but in a bit of rush to order before the Black Friday deal ends!

Most sellers on line of rings offer a size guide. I tried one anD my fingers appear to be off the scale !
