Let's start with everything you need to know to know if a quartz is authentic.

One of the most interesting properties of quartz that can get you out of the trouble of knowing if the quartz is authentic is the absence of bubbles inside the mineral.

In nature, quartz is found in very diverse forms having imperfections, however, if you observe that the imperfections are very round... they are bubbles! Bubbles are a clear symbol that we are not in front of a quartz but a simple crystal.

2. Check the hardness of the quartz to know if it is genuine. 

If you are still not sure if your quartz has bubbles or imperfections, another essential step to know if your stone is a quartz is to check its hardness.

To do this, take any type of glass and try to scratch it with your quartz. If the glass scratches it will be a quartz, but if it does not scratch or it is hard enough, you will be in front of a false quartz.

Quartz has a very curious property: the polarization of light.

Therefore, the last simple way to check the authenticity of a quartzis by observing the sky through our stone.
