I remember seeing a ring with extremely round edges and the colors pale copper and gray (or gold) combinations in half cylinders.
It had two pale copper and one gray (or gold) half cylinders, with the gray (or gold) half cylinder between the two pale copper cylinders.
The outside of the ring had three half cylinders (two pale copper and one gray (or gold)), while the inside was flat and pale copper in color, and the edges of the ring were extremely round and a cylinder.
The ring had three half cylinders stacked together in one ring. Two pale copper cylinders are placed between a flat pale copper, and the gray (or gold) cylinder is placed above the flat pale copper.
It was also a wide ring. Does anyone know about this ring design?
Edit: Here is an image of a ring that looks similar to my design. Only the edges should be pale copper, and the middle should be gray without diamonds:
I was confused reading OP’s description, and I’m also confused looking at your link how you got that from OP’s description. 😅
My thought was than an inset, taken as a whole circle, could be referred to as a cylinder. Like you, I couldn’t really make sense of the description and was trying to interpret it. Based on the response above I was way off.
Because it does sound a bit like they’re describing a banded ring.
But the flat plane part is what leads me to thinking it’s not.
I edited the post to add an image of a similar ring design. You can look at it.
