Sailor Anchor Ring Rose Gold Tone Signet Naval Theme Size 6-7? Unisex

Sailor Anchor Ring Rose Gold Tone Signet Naval Theme Size 6-7? Unisex see photos for condition and measurements. There is some wear to the rose gold plating in one spot. I dont have a ring sizer, but this fits my pinky finger, and I have larger fingers. My ring finger is an 8, so I am guessing that this is a 6.5 or so. I have provided a photo of the interior diameter in centimeters, so please find a ring that fits well and compare measurements before ordering.
