Round Jasper Jupiter Ring 925 Silver size 7

Perfectly round jasper stone set in 925 silver. Warm earthy tones with Jupiter-esque striations. There is a grey sand dollar- type pattern on the top half; it is a particular type of jasper I can’t remember the name of. Slim band stamped 925. No defects. I believe this is size 7 but can’t guarantee. I l am wearing on a 6.5 finger in photos. Simple yet striking; beautiful gemstone with great shine and intricate patterning up close.
