Translucent Rutilated Quartz Cut Gemstone
Rutilated quartz, also known as golden rutile, and rutile quartz, is a type of included quartz.
It's clear quartz with needle-like inclusions of the mineral rutile, which is composed of titanium dioxide.
Rutilated quartz is best know for its golden-coloured inclusions, although they can also be black or deep reddish-brown.
The rutile crystals grow very slowly in different directions within the quartz over millions of years.
