What is the rarest gem?
PainitePainite was first discovered by British gemologist Arthur Charles Davy Pain in 1951 and recognized as a new mineral in 1957.
For many years only one specimen of the dark red crystal was in existence, housed at the British Museum in London, making it the world’s rarest gemstone..
What is the softest animal?
ChinchillasChinchillas are rodents that live at elevations of 3,000-5,000m (9,800-16,400ft) in the Andes Mountains of South America. To survive in the bitter cold, they have very dense fur. They achieve this by growing more than 50 fine hairs from each follicle. Their fur is considered to be the softest in the world.
What is the softest body part?
Most probably its brain but fat tissues are considerd as the softest tissues in human body. Actually Soft tissue is a broad term that covers various groups of cells within the body. Each of these cell groups, or tissue, serves a purpose related to the body parts they are connected to.
What is the hardest and softest mineral?
Talc is the softest and diamond is the hardest. Each mineral can scratch only those below it on the scale. Look at the scale below – click on the pictures to find out about each mineral.
Is there a mineral harder than diamond?
Source: English Wikipedia. (PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
What is the softest thing ever?
According to the Mohs scale, talc, also known as soapstone, is the softest mineral; it is composed of a stack of weakly connected sheets that tend to slip apart under pressure.
What is the weakest gem?
talcIt’s a bit of a trick question. The weakest MATERIAL is talc. This is drilled into every geology & geography student when learning Mohs Scale. A mineral has to be strong enough to be cut and polished to be a gemstone.
What is the most strongest rock in the world?
Diamond is the hardest known mineral, Mohs’ 10.
What rock is the softest?
talcThe name for talc, a sheer white mineral, is derived from the Greek word talq, which means “pure.” It is the softest rock on earth.

What is the hardest stone?
DiamondsDiamonds are the hardest stone, while talc (for example) is a very soft mineral. The scale by which the hardness of minerals is measured is the Mohs Hardness Scale, which compares the resistance of a mineral to being scratched by ten standard reference minerals that vary in hardness.
What is the softest mineral on Earth?
TalcIt is the softest known mineral and is assigned a hardness of 1 on the Mohs Hardness scale. Talc is a monoclinic mineral with a sheet structure similar to the micas.
What is the strongest mineral in the world?
1. Diamond. Diamond is the hardest known natural mineral according to the Mohs scale. Its hardness depends on its purity, and the hardest diamond can only be scratched by other diamonds.
Is talc the softest mineral on Earth?
Talc is the softest mineral on the Mohs hardness scale at 1 and can be easily cut and crushed. Talc has perfect cleavage in one direction. This means that it breaks into thin sheets. As a result, it feels greasy to the touch (which is why talc is used as a lubricant).
