Sorry for the late reply, but of course you can! I used an extremely similar texture as the one that ruby was supposed to be. Because if you didnt know, emerald was supposed to be ruby, and this was the texture that was going to be used. So it isn't exactly mine to approve, but I dont mind.

Thank you so much! This is my first pack and I was kinda tired of the old textures, so I changed them a bit. Im really glad this pack is getting attention.
