Crystallography




The other day, my neighbor asked me who discovered the properties of crystals and it got me thinking: how do I have my crystal healing certification and I don't know the answer?

I decided to dig into it and this is what I learned:

Crystallography: The branch of science that deals with discerning the arrangement and bonding of atoms in crystalline solids and with the geometric structure of crystal lattices. 

Historical references to the use of crystals is believed to have started with the Ancient Sumerians (4th Millennium BC) and date back at least 5000 years in traditional Chinese Medicine. Ancient Egyptians are also known to use crystals such as lapis lazuli, turquoise, and quartz in their jewelry. They also used stones for protection and health as well as for cosmetic use such as grinding stones like malachite into an eyeshadow. It was also found that in Ancient Mexico green stones in general were used to signify the heart of the deceased during burial. 

The word "crystal" comes from Ancient Greece identifying quartz with the word "crustallos" meaning very cold icicles of extraordinary hardness. 

Theophrastus (c. 371 – c. 287 BC) classified rocks and gems based on their behavior when heated, grouping minerals by common properties, such as amber and magnetite, which both have the power of attraction.

so to answer my neighbors question, I think it was totes this guy.

THEOPHRASTUS, (ca. 372 B.C. - 287 B.C.). "De Lapidibus" in Eis Organon Aristotelous [Opera Graece]. 5 vols. Venice: Aldus Manutius, 1495-1498.

 

In Ancient Rome, the first reference to crystals was reported by Pliny the Elder in his book "Natural History". In Italy Georg Bauer (1494-1555) is considered the father of mineralogy, and made the first classification of minerals based on their physical properties.

In July 2012, the United Nations recognized the importance of the science of crystallography by proclaiming that 2014 would be the International Year of Crystallography. 

The study of crystals was based on physical measurements of their geometry using a goniometer allowing the symmetry of the crystal to be established. Today, we have X-Ray Diffraction Crystallography. This science determines the atomic and molecular structure of a crystal using x-rays that diffract into many directions. Using this science, a crystallographer can produce a 3D picture of the density of the electrons within a crystal.
