    Sleek, Unusual, Vintage New Old Stock Sterling Silver Modernist Ring. The central open loop portion is polished, while the band is a contrasting satiny, textured finish.   The ring is a size 8. The face measures just over approximately 3/16 of an inch, or about 5 millimeters high and about 1/8 of an inch, or approximately 3.17 millimeters, thick. The band narrows to just over roughly 1/16 of an inch, or about 2 millimeters, wide. (Included you'll see a US Quarter in the photographs, for the measurement-challenged and ruler-averse.) It is stamped inside, "925", along with an illegible mark which may be a signature. Weight is approximately 4.6 grams.     This is new old stock ring, never sold or worn, but
