Size 9
Signed by yours truly. 

Size 9/ 18.9mm.

To figure out a rough estimate in size, you can take an existing ring you own and measure the inside of the circumference in millimeters and find it on the chart. 
Keep in mind, this will only give you the size for that finger in which that particular ring goes on. ;)

The ring can get wet, though it is recommended that it not be exposed to it so often.
It is coated with UV protection varnish. 

The painting itself was done with high quality, intense pigment Holbein Artists' Gouache. 

**** This is a fine art item.
