The ring is approximately a size 6 and 1/2. The band measures just under approximately 1/4 of an inch, or about 6.35 millimeters wide. The band measures about 1/16 of an inch, or about 1.5 millimeters, thick. (Included is a US Quarter in the photographs, for the measurement-challenged and ruler-averse.) It is marked inside, "Tungsten Magnum", and signed, "N".
This is a vintage piece, which has been worn and enjoyed. There will be the expected light surface scratches and possibly a few dings from normal wear. The thick ring remains round and true. Lightly hand cleaned, but it may need further attention.
A very nice, unusual and very durable tungsten ring. Eye-catching sparkle, in a fierce, chunky, style.
