New Spyglass Upgrade

I think in addition to new big dark cave. It can be hard to see all the ores. So i have an idea. So when you use your spyglass in these dark cave the more valuable ores (Emerald, Gold, Diamond, Lapiz) will give a little sparkle sometimes this will give you a little hint about which ores a where. And this will also get people to use the new spyglass even more!
