CaB 2 Si 2 O 8, Calcium boron silicate.
A specimen of Danburite Crystals on Matrix.  A big specimen in its natural form.  This mineral is getting a lot harder to find, possibly because of its location.  Danburite is not a well-known mineral but is growing in popularity.  With crystals similar to topaz, danburite offers a unique opportunity for a collector who likes perfectly transparent crystal clusters.  People who admire clear quartz will like the different look of danburite.  Its diamond shaped cross section and wedge like termination is a contrast to quartz’s hexagonal prisms and pyramidal terminations.  Danburite’s original locality is now buried under the city of Danbury, Connecticut.

CaCO3, Calcium Carbonate.
Calcite, which gets its name from “chalix” the Greek word for lime, is a most amazing and yet, most common mineral.  It is one of the most common minerals on the face of the Earth, comprising about 4% by weight of the Earth’s crust and is formed in many different geological environments.  Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types.  It forms oolitic, fossiliferous and massive limestones in sedimentary environments and even serves as the cements for many sandstones and shales. Limestone becomes marble from the heat and pressure of metamorphic events.  Calcite is even a major component in the igneous rock called carbonatite and forms the major portion of many hydrothermal veins.  Some of these rock types are composed of better than 99% calcite.  Why would a collector be interested in such a common mineral? Its extraordinary diversity and beauty!
