Most all quartz is originated from China or the Czech Republic. The final glass is then welded, cut and finished in the USA. We have searched and searched for an American quartz manufacturer and have come up short time and time again. What makes quartz good is if it was made from high quality. There are many qualities from China and the Czech Republic. One thing we have noticed is most all the new designs originate in the USA and are then copied in China. Even some of the big boys are now getting their quartz from China and saying they make it. We will always let you know where our glass originated from.
