Diamonds, diamonds, diamonds! Nah bro that's glow lichen.

While if you did then, Whistler's Better Glow Lichen is a funny little texture pack which changes the texture of glow lichen to diamond ore to make it feel like you just started Minecraft again. Use this pack if you want to add a little extra challange to your world! (The texture is not perfect because the normal diamond texture is different then the deepslate texture, so it can't be perfect... but it still looks pretty convincing from far away!)
