Which is the softest solid?
Talc is the softest mineral on Earth. The Mohs scale of hardness uses talc as its starting-point, with a value of 1. Talc is a silicate (like many of the Earth’s most common minerals), and in addition to silicon and oxygen, contains magnesium and water arranged into sheets in its crystal structure.

Which gemstone is most powerful?
Diamond. It is not only one of the most expensive gemstones, it’s the strongest one.
What is the hardest precious stone?
A stone’s Mohs rating provides a measure of its scratch resistance to other minerals. Diamond is known to be the hardest and can scratch any other stone. Talc is the softest. Reference minerals in between include gypsum, calcite, fluorite, apatite, orthoclase feldspar, quartz, topaz, and conundrum.
What is the rarest fabric on Earth?
Vicuna goods sell for roughly five times the price of similar cashmere products. Nature has made the vicuna so perfect, so amazing… that its wool is considered to be the finest in the world,” said biologist Santiago Paredes Guerrero.
What is the softest fiber on Earth?
