Specific gravity of corundum is between 3.95-4.01.
the garnet is lusciously 5.0 on the MOHS scale of minerals. (hardness).
A ruby doesn't really have brightness, but it reflects light.
On earth the gravity of a ruby is 9.81 m/s^2
If you mean the specific gravity of ruby:
3.97 - 4.05
It has a specific gravity of 3.1-4.3
Aluminum has no specific gravity, at least by the current definition of gravity.
specific gravity of fly ash is 3.2
Specific gravity doesn't have units. It's the density relative to water, so specific gravity is effectively just a number.
"Specific gravity" or "specific density"
Every substance has a specific gravity. Aluminum's is around 2.6 .
Ferromagnesian minerals are minerals that have iron or magnesium in their structure. The greater specific gravity is between 3.2 and 3.6. Some examples are pyroxene, biotite, garnet, and olvine.
An andradite is a specific mineral of the garnet group.
To learn the identity of the gemstones opal, diamond, garnet, and topaz you need to look at their color, transparency, specific gravity. You need to light the stone's surface and look through a loupe. You also need to determine the birefringence and refractive index.
The specific gravity of diamond is 3.5, which is 'above average'.
There is no such thing as a specific gravity for any element.
Aluminum has no specific gravity, at least by the current definition of gravity.
helium doesn't have a specific gravity
mica has the specific gravity of 2.88
specific gravity of soil
The specific gravity of lithium is 0.534
Specific gravity of ppc is 3.15
specific gravity of acetone is 0.79
