1 Clear Quartz Tumbled Stone -  A Quality - Master Healing
 
Known as the ‘Universal Stone,’ Quartz is the second most abundant mineral on Earth next to feldspar. It forms in almost all mineral environments at all temperatures.  It is present in igneous, sedimentary, and metamorphic rocks. Even the sand of beaches, rivers, and deserts contain significant amounts of Quartz.
 
With a Mohs hardness rating of 7, Quartz is a highly durable mineral. It remains very stable even when exposed to extreme temperatures and harsh chemicals. 
It easily forms rounded or shell-like conchoidal fractures when subjected to pressure. This is why Quartz crystals naturally have marks or grooves on their surface. It also has a vitreous or glassy luster.
 
Pure Quartz has a clear or white colour. However, the presence of mineral impurities can make the mineral purple, pink, green, yellow, orange, blue, or red. For instance, Amethyst (the most common variety of Quartz) can display a lilac to deep purple colour due to traces of iron in the stone.
