Spectacular aventurine Men's ring, Silver with gold vermeil, retailer size 13

This is a spectacular Men's aventurine ring. It is excellent condition, with gold vermeil on the side and retailer the stone measures 1/2 inch by 1/2 inch. The stone tests as quartz. I cannot tell if it is natural, or any dye has been added. The size of the ring is a 13 and it is large. The color is deep and serious. The workman ship on the band is exceptional. An excellent ring all the way around.
