Rutilated Quartz Rutile a mineral with a hardness of 6 on the Mohs hardness scale is a major ore of titanium. It often forms needle-like crystal inclusions inside quartz. This type of quartz is known as rutilated quartz and its inclusions look like small bars of imbedded gold. Rutilated quartz is found in Australia Brazil Kazakhstan Madagascar Norway Pakistan and the United States. Because of its exotic beauty the Jaquet Droz Company decided to use rutilated quartz from Brazil as their dial material. The hardness of quartz is 7 and because of the difference in hardness between the two materials and the way rutile forms inside the quartz it is very hard to craft. The material has to be carefully selected in order to find a very fine smooth surface without pits and with a sufficiently large concentration of rutile inclusions to make a beautiful dial.
