Definition: The term "amiantus" in Greek literature has not been definitively identified, but it's commonly associated with the name of a specific type of rare metal alloy known as Amiantite. The English translation often translates this as "diamond", or more specifically, ametrine. Ametrine is a white solid compound primarily composed of sodium and magnesium silicate, which is sometimes called a diamond by its chemists for this reason. The chemical formula for ametrine is Na2Si3O8(OH)2, where O is oxygen, H is hydroxy group, and the amantine unit (OH) indicates an ametamine. In Greek literature, "amiantus" or "diamond" often refers to a rare metal alloy that is composed of sodium silicate and carbon. This substance was first mentioned in ancient texts such as Homer's epic poem "The Iliad," which depicts the Trojan War between Trojans and Greeks. The term "Amantine" is also used in Greek literature to describe this material, but it is not clear whether it is specifically ametrine or some other mineral compound. It's worth noting that despite its unique properties as a diamond, ametrine is typically encountered in smaller quantities due to the difficulty of extracting and refining it.
