Nature did an amazing job of placing interesting quartz “bookends” on both sides of this beautiful varied green serpentine. I cut the sides and angled the top to accent the shape and give it additional character.
Rock type: Serpentine/quartz
The name serpentine can refer to a specific type of rock, however I have found that it is also used for a catch all name for many metamorphic green rocks. Serpentines are ultramafic metamorphic rocks and contain a wide range of rich green colors.
Chemical composition: Serpentine minerals typically have a general chemical formula of (Mg,Fe)3Si2O5(OH)4. Quartz = SiO2.
