Purple Amethyst Drusy Ring in Gold Washed Sterling Silver Size 7 1/2

1970s nugget style gold washed sterling silver ring set with a large amethyst drusy. If you look closely you'll see three small white faceted quartz stones that are prong set and separate stations around the drusy. It is a size 7 1/2 Face measures 1" by 7/8" and the stone stands up 5/8" from the finger. 

It is hallmarked inside. I can made out the word "sterling" but not the word above it. Weight: 17.2 grams.
