I guess that helps define the difference. I have been pricing rough to cut and can understand choosing synthetic to experience the stone and master a more difficult material. The quartz I am cutting today is from a box of rocks from North Carolina. The material appears to be genuine as I have to trim and cab to find a near flawless piece. I do enjoy going through the process. My collection is putting me into a position of others wanting to own it. Which is good, for a beginner. I like setting my stones too which is another topic.
