Frequently Asked Questions

Q. "Are real diamonds used in these faucets or their parts?"
A. Yes, but not the diamonds you would typically find in a jewelry store. Carbon (the source of diamonds) is taken and electrically charged. Then, using high amounts of pressure, fused to a ceramic plate, creating a diamond coating that is clear and nearly indestructible.
