Out of all the stones in the world, one of the most classic and elegant is the quartz crystal. Quartz is actually known for being the second most common mineral in the Earth’s continental crust, and so although the quartz stones are quite common, the quartz crystal in particular is not.
Let's face it, the common old quartz crystal is still a favorite of all rock lovers everywhere! I have a large collection of various mineral specimens, some of my favorite pieces are inexpensive quartz crystals and for no other reason then I Like Looking At Them!
Quartz crystals come in such a wide variety of shapes sizes and configurations, and can have so many different inclusions of other minerals that you can't help being fascinated by them !
The quartz crystal is a crystalline rock that is composed of silicon dioxide, and there are actually a few different groups of these quartz gems, which are differentiated by their exact composition as well as by their crystalline structure. Pure, clear quartz is called rock crystal. Rock Crystals always show a six-sided outer form, but inside, when you break them, they have almost no cleavage direction. Instead they have a conchoidal fracture, in which the broken surfaces show scooped-out, shell shaped forms. Conchoidal fracture and the glassy luster are very typical signs of quartz.
The groups are as follows: fully crystalline quartz, which is the group that includes rock crystal, amethyst, citrine, and smoky quartz. Then there is the quartzite group, which is the group that is composed of a interlocking mass of quartz crystals with irregular boundaries, and for instance aquamarine quartz is included in this group.
Finally there is the cryptocrystalline quartz group, which is a group with particularly microscopically small crystals of quartz that is embedded in opal, which is otherwise known as hydrated quartz.
Besides being classified into different set groups, there are also main gem varieties of quartz crystal, and this includes: agate, amethyst, aventurine, bloodstone, citrine, cairngorm, cat’s eye, chalcedony, chrysoprase, cornelian, fire opal, hornstone, jasper, onyx, opal, petrified wood, plasma, prase, rock crystal, rose quartz, and tiger’s eye.
If you are interested in buying any type of quartz, you have the option of either buying it in natural stone form or in a piece of jewelry. When buying stones in general, you always want to make sure that you are working with a respected jeweler, one that you can trust, and this is primarily because the opportunity for deception in regards to gemstones is so great.
You also want to keep your eyes open for imitation stones, because they can be easy to miss and there have even been cases where the jeweler was not even aware of the mix up. As well you always want to take the time to shop around, as there are numerous different companies that operate in this field and so the prices are going to fluctuate more than they would in other types of markets.
Perhaps most importantly of all, always make sure that you have all of your receipt details, so that if you are not satisfied at any point you have proof and can bring your purchase back.
