Have you ever wondered whether the precious gemstones you buy are real or just a piece of rock? If you are interested in gemstones, then there is rarely a chance that you aren’t aware of turquoise.
Turquoise is a beautiful, opaque, and exquisitely colored gem. But the question that often arises is, is turquoise a rock?
Turquoise is often a popular choice among the ones who are fond of gemstones. To understand whether it is a rock or not will give you a clearer idea of its properties and uses.
Here, I’ll be providing better clarity about the composition and formation of turquoise.
What is The Formation of Turquoise?
Gemstones are usually considered to be a mineral. When it comes to the formation of turquoise, it is a secondary mineral shaped when pre-existing minerals undergo weathering or sometimes oxidation. The mineral is opaque and is available in different colors.
If we talk about the chemical composition of turquoise, then it is a hydrous phosphate. The hydrous phosphate is of aluminum and copper. The mineral is often found in the form of microcrystalline, nodules, and sometimes as veins.
The most common areas where you can find turquoise are arid zones. They are often present in the cavities of volcanic rocks or crammed rocks. Therefore, the weather has a huge role to play when it comes to the formation of turquoise. It keeps on changing till it reaches its final state.
What are The Properties of Turquoise?
If you want to distinguish Turquoise from a rock, then it is important to note turquoise’s properties. Given below are some properties of turquoise.
The first thing that comes to the notice is the color of the mineral. Turquoise is present in a wide range of colors. This includes sky-blue, blue-green, blue, and many others.
The beautiful array of colors makes it very catchy to the eye and also exquisite. It is opaque and sometimes transparent in appearance.
Turquoise, when it comes to tenacity, is brittle. This means that though it may look hard, it still tended to break when exposed to some pressure.
The chemical composition of turquoise is also an important property. The turquoise is a hydrous phosphate. The hydrous phosphate is of aluminum and oxides. The continuous weathering of pre-existing minerals forms it.
The coloring of the mineral is because of the presence of copper. There are ongoing studies to understand what role copper plays in the composition of turquoise.
Turquoise is triclinic. The occurrence of turquoise is very rare in the form of minute crystals. They are usually available as cryptocrystalline and are massive.
Is Turquoise a Rock?
Turquoise is a precious and popular gemstone. The demand and availability of turquoise in the market have also given rise to fake ones. There are rocks often sold as turquoise. So how will you figure out is turquoise a rock?
Here are some factors that will help you sort out the basic differences between a rock and a turquoise.
The first time to observe while telling if turquoise is a fake rock is to check its physical appearance. The color of turquoise can be a wide range of green, blue, and brown. There is a very rare chance that the color will be distributed very evenly. There is always an irregularity when it comes to the color of turquoise.
If you notice that the color is properly and uniformly spread on the stone, then there is a high possibility that it is dyed and is not real. There is also webbing present in the real turquoise. This is another physical feature that you can use to find a rock apart from turquoise.
The webbing on turquoise can be of different colors, including black, yellow, and brown. The perfect way to find out turquoise is to use a fingernail to scratch the upper part of the turquoise. If in the webbing your nail gets caught, then most probably the turquoise is not a rock.
The Stability of the Color
The test to check the stability of color in turquoise is very important to check if a general rock is dyed instead of turquoise. The things that you will require are good acetone and tissue. This test is often called a destructive test.
Acetone is a great thing when you want to figure out if a rock is dyed as turquoise. It is called the destructive test because the stone gets destroyed if it is fake.
If you try to wipe the stone with acetone and turn it into a lighter color, then the turquoise is real. This is a great way to know if your turquoise is a stone or not.
Since the gemstone is very popular, the price point is another way to figure out if it is a rock. If you think that the price is too affordable and cheaper than the other places, then that is a red flag for you. Lower prices always put a question mark on the authenticity of the gemstone.
So, you must avoid the stone if the price quoted looks too good to be true.
Keeping in mind the above-stated points, you can easily figure out the authenticity of a stone. After this, you will be able to tell is turquoise a rock or not.
Uses of Turquoise
Turquoise is gaining popularity with each passing day. It is widely used as a gemstone and is also known to have healing powers. Turquoise is often connected to prayer, spirituality, and its beautiful appearance also makes it very popular to wear. Turquoise, just like its wide availability and colors, has a lot of uses as well.
Summing It Up
Turquoise is an exquisite, opaque and stone that is available in various colors. This is a secondary mineral formed by the weathering that happens in the minerals that already exist. Once you know the properties and composition of turquoise, it would be easier for you to figure out if it is a rock.
Finally, I would suggest to research and stay at a distance from dyed stones.
