Lapis Lazuli texture improvement

Today, Minecraft has new textures with much more detail than before,
I love the new textures of the game. That's why I've been thinking a lot about how I could
contribute with something for this wonderful game.

So, here is my idea.
In real life,common Lapis Lazuli isn´t pure at all. One of the most prominent minerals
that compose lapis is pyrite, a mineral with a golden color. It would be great to have that color
on lapis.

Here is a sketch of how it could be like.

I hope you liked my idea. I have been a big fan of this game for a long time and I wanted to thank the Mojang team for all their work. Thank you :D
