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.
tigereye, also spelled Tiger's-eye, semiprecious quartz gem displaying chatoyancy, a vertical luminescent band like that of a cat's eye. Veins of parallel, blue asbestos (crocidolite) fibres are first altered to iron oxides and then replaced by silica.
Milky white quartz is a bit difficult to price because it can sometimes be worth as little as $1 per carat or as high as $4 per carat. It really depends on his situation. Iridescent quartz is generally less expensive because it is not as visually appealing as some of the other quartz crystals available.
Blue Rose Quartz is a type of in-between Girasol and Rose Quartz that does actually have a blue hue to it in some light, pink in others, and when you hold it up to the light, gives a golden glow.
Milk quartz or milky quartz is the most common variety of crystalline quartz. The white color is caused by minute fluid inclusions of gas, liquid, or both, trapped during crystal formation, making it of little value for optical and quality gemstone applications.

But often the price of gold-bearing quartz is more than the value of the gold. Specimens are highly prized raw once you've got all the dirt out. If there's a lot of surface gold on a piece it may end up selling for twice the actual spot value of the gold if you can find a buyer.

Diamond has a hardness of 10. Diamond will scratch quartz, but quartz will not scratch diamond. Topaz (hardness 8) and corundum (hardness 9) will also scratch quartz but not diamond.
Quartz naturally vibrates at an exact frequency and contains piezoelectric properties, which means that when it is pressurized, it produces a small volt of electricity. The inverse of this is also true, so that when an electric current is passed through quartz, it vibrates, usually at 32,768 times per second.
Quartz is 100 percent a natural material made up of a white or colorless mineral. But, unlike natural stone, such as marble, granite, and soapstone, quartz countertops are categorized as a man-made product.
