Amethyst is 7.0 on the Mohs hardness scale; it is fairly hard. Amethyst is a member of the quartz family. Most citrine on the market is reported to be heat-treated amethyst.

How are smoky quartz and rose quartz alike?

Amethyst is a variety of quartz. It has a composition [chemical make-up] of SiO2 [silicon dioxide], as all varieties of quartz do. Pure Quartz with no inclusions or pigmentation [coloring] is called rock crystal. But amethyst is principally colored by traces of iron.Amethyst belongs to the geological group named silicates-tectosilicates and has a trigonal or hexagonal crystal system. The color of amethyst is purple, and it bears a hardness of 7 on the moh's scale of hardness.When streaked, amethyst appears white, and it bears a conchoidal fracture. Amethyst is 2.7 times heavier than water [has a specific gravity of 2.7] and can be turned into citrine with heat treatment.So in summary, the composition, geological group, hardness, streak and specific gravity is the same as all quartz are. After all, amethyst is a variety of Quartz.


What is the specific gravity of magnetite?

There is no such thing as a specific gravity for any element.


Why is the specific gravity of mercury on the moon not the same as its specific gravity on earth?

The specific gravity of a substance depends on the acceleration due to gravity. Since the gravity is lower on the moon than on Earth, the specific gravity of mercury will be different between the two. On the moon, the weight of mercury would be less than on Earth due to the weaker gravitational pull, causing its specific gravity to be different.


What is the specific gravity of polymer?

The specific gravity of a polymer can vary widely depending on its specific composition and structure. In general, the specific gravity of most common polymers typically ranges from 0.9 to 1.4. It is important to consult specific material data sheets or conduct tests to determine the exact specific gravity of a particular polymer.


How much does amethyst cost?

The cost of amethyst can vary depending on the quality, size, and origin of the stone. In general, small amethyst crystals or tumbled stones can be purchased for a few dollars, while larger, higher-quality amethyst specimens or jewelry pieces can range from tens to hundreds of dollars. It's best to research specific sellers or stores to get an accurate price for the type of amethyst you are interested in.
