Artificially, this mineral is manufactured using seed crystals called lascas.
Artificially, this mineral is manufactured using seed crystals called lascas. This mineral typically lacks a true crystal shape since it forms within the spaces of other crystals; that feature is due to the fact that this mineral is the last to crystallize from cooling magma, putting it at the bottom of Bowen's reaction series. Aluminum 3 plus ions are in the smoky form of this mineral, while traces of iron gives this mineral an orange hue, a variant called citrine. Amethyst is a form of this mineral, whose piezoelectric properties allow it be used an electronic oscillator in modern clocks. For 10 points, name this second most abundant mineral in the Earth's crust, composed of silicon dioxide.
