Lower
A properly Minimize emerald will provides the emerald a bigger sparkle and glow to its greatest capability. The Lower isn't as crucial to the emerald, because as mentioned before the coloration is what makes the emerald additional useful. The form, width and depth on the emerald make up the Reduce.
