^ It will be crumbly to the touch and, depending on exactly how unrefined it is, it can be anywhere from a cream color to a deep yellowish with a hint of brownish color.
The best way to know, though, is that crumbly feeling to it. It will break up in your hands or under your fingers when you are trying to get it out of the tub...or if you bough it in chunks, you can tell simply by looking at it. You absolutely have to soften pure shea butter by holding it in your warm hands and rubbing your hands together to get it to a smooth, oily consistency.
I bought mine in a tub, packed down but never previously melted...maybe softened a little to get it into the tub. I am going to melt, add Vitamin E and cocoa butter and whip mine this weekend....
Hope this helps!
