Are those real gemstones in the snake's eyes? The snake's eyes are made from synthetic onyx. If you look closely, you can even see the carefully cut facets that give the eyes such a lifelike shine. I swear, sometimes this ring looks almost alive.
Did St. Patrick really drive the snakes out of Ireland? Well, Ireland is one of the few places on earth without a native population of snakes (Iceland, New Zealand, and the North and South Poles also missed out). However, there are some who argue that the St. Patrick legend is really a metaphor for him bringing Christianity to Ireland, and driving the pagans out. If that's the case, though, I can tell you for a fact that he missed a few!
