Vintage Size 6 3/4 Lucite Ring Chunky Flat Top Dome Black Mid Century Modern

Vintage black flat top lucite ring. See last 3 photos. This ring has a scratch on the flat top. Noticeable and not depending on angle. Can be polished off with a polishing wheel. 1970's unworn inventory. These are not from a mold. Each ring is sliced and polished. If I have 2 of the same rings in different sizes they will differ ever so slightly because they're hand cut. Stock photo will show one or both. Feel like Bakelite but they're lucite. Size 6.75 approximately. Look at sizing rod. Heavy for their size. Enlarge all photos so you know exactly what you're getting. They're an integral silent part of my items' description.
