BOLD, crazy, a mix of modern and wild, unusual and ... did I said crazy? This totally cool ring has as stone of choice an antique Conus shell currency nested in solid sterling with a solid sterling band that as is it fits a finger size 8 1/2 but can be made to a maybe an 11 comfortably since it has an adjustable band.
The "coin like" elements where the conus rests is shibuichi -my new love- that oxidizes to a golden gray like silver in a warmer tone -shibuichi is a mix of fine silver, copper and a touch of gold-
 
The band is Wide and Hard, you can see the ring on my index finger, I'm tall, lift weights as a sport -my hands manage extreme weights and are muscular and extremely strong- and hammer metals for a living, so that gives you an idea that I have not small hands, LOL, so if you have soft small hands, it might not work for you. Bad @ss 100% with the wild antique touch.
-Sorry for the light in the video, had to make them with artificial light. :( -
