Sorry for the pun that you'll see in a minute

So I was thinking about my Diamond Totem texture pack, and then I started thinking about Aphmau and some movies I've seen, and then I came up with the idea for the blood diamond. I got the item ok, but the diamond block looks a bit plain. I wasn't able to shade it very well. Originally, when I made the texture for the diamond ore, it was suposed to look like a brighter redstone ore, but when I loaded in my texture pack and checked to see how it looks, it seemed like the red had bled into the stone, which I guess makes since.
Anyways, this is my 3rd texture pack, and if anyone has any suggestions, please leave them in the comments!
