Hi Kawabi,
Thanks for the question. Granite doesn't have brand names because it's a natural material (the same way you can't pick a brand of wood, only the company that prepares it for the market.) Santorini is a color of granite. You can kind of think about how elm, oak, and cherry are all wood, but have different characteristics, so it is with granite. Granite is usually grouped by the quarry spot it came from and the color formations. Santorini can be recognized by its signature red/ pink color pattern. An exotic granite just means it's much rarer and thus more expensive. Exotic granites can be harder to cut and install, but sometimes they are just very uncommon. For example, the granite in my home showed up for a short while on the market and there was never a granite just like it again. Supply and demand. Hope this helps answer your questions!

I did not read all the comments! Someone may have said this already, but this stone is it NOT quarried in the Middle East. This stone is from the NorthEast of BRAZIL.
