Do you know about quartz and its Quality? Quartz which is also called silicon dioxide is one of the most common minerals found on the earth’s surface. Quartz covers a wide variety of stones, many of which are used decoratively for their durability and ornamental nature. For sure for those who like jewelries, you heard about the different types of quartz like: Amethyst (purple quartz), citrine (yellow), rose quartz (light pink), and smoky quartz (dark, translucent gray). To know if the quartz you’re buying is high in quality, first you need to check if it’s real or manufactured and you can do it yourself without the help of an expert. You can check the temperature and weight of the quartz in your bare hands, if it is heavier than a similarly sized piece of plastic; it is probably of a relatively high quality. Also, check to see what the surface temperature of the quartz is prior to handling it. Good-quality quartz is cool to the touch, like glass; a piece of plastic that has been manufactured to resemble quartz will feel warm or room temperature to the touch. Well it is easy and fun! Keep in mind, however, that glass made to resemble quartz will also be cool to the touch, although it will be smoother and less varied. Examine the color of quartz. Naturally occurring quartz will have irregular striations and color distribution. Check the quartz for cracks and fissures. Quartz is more valuable when it is completely intact; however, a piece of naturally occurring quartz of unusual color is still worth more and of higher quality than a smooth piece of manufactured plastic or glass designed to imitate quartz. The external surface of the gem may be covered what looks like dull rock, while the interior shows a glossy, colorful surface – this means the quartz was mined from part of the earth’s surface, making it a higher-quality specimen.
