1.4" Polished Blue Quartz Egg - Utah
This is a small polished egg sculpted from blue quartz collected in Utah. Like many other forms of blue quartz, the blue color can likely be attributed to dumortierite inclusions.
Dumortierite is an aluminum boro-silicate mineral that often forms as fibrous aggregations. The crystals are typically blue, however grey-blue, green, and brown crystals are also common. In rare cases, the crystals can be violet or pink. Dumortierite is often found as fibrous crystals within massive quartz: blue dumortierite-included quartz, known as "dumortierite quartz" crystals, are highly sought after.
