For some reason this reminds me of a crown - probably due to the "bumps".
The ring is made from 22g sterling silver sheet that was run through a rolling mill to give it a nice background texture. The "bumps" are scrap silver that was heated until they shrunk into little balls. Very fun to watch metal do that when heated. A patina was applied to accentuate the patterns.
The ring fits a size 7.
Copper and silver will tarnish unless sealed and stored properly. Use a high quality jewelry polishing cloth if needed. A small anti-tarnish pad is included with the purchase and should be kept with the ring. I always suggest removing rings before washing hands or dipping them in any liquids.
