Large Vintage Silver Indian Cuff w/ Multiple Stones Statement Piece Bracelet

Large vintage silver cuff with multiple stones, bought in India 50ish years ago by my world traveled friend. There are no markings on this piece, beyond the Made In India, but I've been able to clean it up quite a bit with silver cleaner so I dont think it's made from some cheap pot metal. The big stone is a light tanish yellow, and there are three smaller stones on each side that are dark green, deep purple and opaque brown. My best guess is the big stone is a yellow agate, green stones are malachite, purple are amethyst and the brown stones are amber or tiger eye. I am Not a geologist, but I have now wasted an hour looking up different stones on the internet, trying to find the best match. This is an Incredible statement piece that will get Allllll the compliments. Would make a great gift.
