Gemstones are those beautiful rocks or stones, gems that come from the earth. Yes, some are made in a laboratory by man, but I prefer the ones made by Mother Earth. To understand that they may have taken billions of years to get to the point they are when a miner extracts them from the ground, simply amazes me! Heat, cold, pressure, and all sorts of chemicals all play a role together to create these lovely baubles.
Without going into all of the science behind geology and gemology, we will stick to the simple basics about gemstones. All gemstones have a Species and a Variety. The Gem Species is a broad gem category based on chemical composition and crystal structure. The Gem Variety is a subcategory of the species based on color, transparency, or phenomenon. To translate, think of the Species being a Dog and the Variety would be a specific breed of dog. A different Species would be a Cat. Get it?
The Species Quartz is one of the most important minerals on earth and makes up one of the most popular gemstone groups in the world of colored gemstones. It is an attractive, durable, and inexpensive gemstone that can either be cut or carved into many forms and sizes. Quartz is the second most abundant mineral found in Earth’s continental crust, second only to Feldspar. A fascinating Variety of Quartz is Ametrine. Ametrine is the result when Amethyst and Citrine, both Varieties of Quartz, grow together into one crystal! Some other Varieties of Quartz include Carnelian, Rose Quartz and Smoky Quartz.
