Quartz crystals are comprised of silicon dioxide and they form in a wide variety of different colors and types. Many are transparent or translucent and they are configured in many different ways, and in a range of attractive colors. Many of the stones made from quartz have powerful healing qualities.
The obvious answer is, more quartz rock, but perhaps you want to know its composition. Of course quartz is composed of silicon and oxygen, but it almost always has impurities. Some quartz with impurities look attractive and we call them gemstones,...
:Specific gravity is a unitless number representing the ratio of a mineral's weight to the weight of an equal volume of water. Gold has a specific gravity of approximately 20.00. Quartz has a specific gravity of 2.65. Water is the standard for specific gravity at 1.00. Woods vary in specific gravity; they usually are less than water, and thus ...
