Jade "Icy Green" Ring Natural Stone

This handmade Jade ring has some wear and tear, approx. size 7 please see photo of ring on mandrel. This type of ring was used to protect the thumbs and was very famous in Royal Mughal court. Color: As per picture upload, it has a green "icy" look to stone. This ring was purchased by my mum. I have described it to the best of my knowledge. it is cool to the touch and hefty in weight. I am listing her many rings because I feel others should be able to enjoy them instead of them sitting in a drawer.
