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.
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.
There is no such thing as a specific gravity for any element.
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.
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.
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.
Light amethyst is a color. A pearl can be that color, but it is not a specific kind of pearl.

Amethyst is a variety of quartz crystal and formed millions of years ago. It is not associated with a specific age as it is a naturally occurring mineral.
Aluminum has no specific gravity, at least by the current definition of gravity.
mica has the specific gravity of 2.88
Specific gravity of ppc is 3.15
The specific gravity of acetone is approximately 0.79 at 20°C.
Specific Gravity.
The specific gravity of quartz is nearly 2.65.
according to Geology.com the specific gravity of Chalcopyrite's is 4.1 -4.3.
Another word for specific gravity is density.
Diamond has the specific gravity of 3.5, which is above average.
