i want to buy a wrist watch a round 800 $ and the dealer says the movement watch is more classic in compare with quarts.
Rutile inclusions begin as molecules of titanium dioxide within molten silicon dioxide (quartz). Titanium is a common impurity in quartz and other minerals. So, as the quartz cools from a semi-liquid state, titanium dioxide present will exsolve and form long crystals of rutile. Sometimes these crystals form randomly within quartz. But, if the quartz structure is already in place, the rutile must grow according to the crystal structure, forming microscopic needles at 60 degree intervals. This forms what is called star quartz.
