This variety of Favosite (aka Charlevoix Stone) is referred to lovingly and obviously as 'honeycomb' with a rich yellowy/ochre color each eye has something completely different in it to see. The ring band is one of my most beloved hand laid texutres on a slightly domed ring band.
 
Size 8.5 and cannot be resized. 
Setting measures approximately 1" x 3/4"
Handmade in my Charlevoix, MI studio in recycled sterling silver.
