The double terminated quartz crystal is a quartz crystal with two ends that end in natural facets. Double terminated quartz crystals are rather rare specimens, and the rarest of all, would be the Herkimer Diamonds. Normally, these crystals form in free floating pockets of liquid that slowly evaporated, leaving perfectly formed crystals with terminations on both sides. Unlike usual quartz formations which grow in igneous rock, double terminated crystals are more than likely found in sedimentary rock laid down by subterranean marine deposits a long time ago. Occasionally, rare clusters of double terminated crystals form – very unique! Double terminated

Quartz crystal cluster properties
The quartz crystal cluster formation is amongst the chief formations that are recognized by the preponderance of crystals in a cluster, appearing as a group type of formation in caves, veins, or geodes. Quartz clusters are formed from multiple crystals joined together at a common base and the sizes of these clusters can range from tiny, to massively huge. Besides quartz, other minerals can also form clusters. An example is selenite. Let us look at quartz crystal cluster properties in this article. The quartz crystal cluster combines the group energy of the entire number of crystals in the cluster, and

Herkimer Diamonds
The Herkimer Diamond is amongst the most unique members of the quartz family because of their resemblance to true diamonds, and yet they are totally quartzite in everything else. Herkimer Diamonds are so named because they were first found in Herkimer County, New York State, but they have since been uncovered in Mexico, Spain, and Tanzania. In USA, Herkimer Diamonds are found not only in Herkimer, but also in Fulton and Montgomery counties. In appearance, the Herkimer Diamond is actually a stout double terminated quartz crystal, but for the untrained eye, they could be mistaken for diamonds. Herkimer Diamonds are

An introduction to quartz crystals
Quartz crystals or silicon dioxide (SiO2) are perhaps the best known of all crystals. It is one of the most common minerals in the earth (about 12%). Our human body contains SiO2 in abundance as well, which would explain the Bible verse that says,”God created man out of the dust of the earth”. Quartz crystals are considered to be the “universal crystal”, and the mineral that most people are acquainted with. Quartz crystallizes as a six sided prism with a termination that ends with 6 pyramid faces. There exists also a double terminated form, which is quite rare. The double
