In [[mineralogy]], '''diamond''' (from the ancient [[Greek language|Greek]] αδάμας – adámas "unbreakable") is an [[Allotropes of carbon|allotrope of carbon]], where the carbon [[atoms]] are arranged in a variation of the [[face-centered cubic]] crystal structure called a [[diamond lattice]]. Diamond is [[Chemical stability|less stable]] than [[graphite]], but the conversion rate from diamond to graphite is negligible at [[Standard conditions for temperature and pressure|ambient conditions]]. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong [[covalent bond]]ing between its atoms. In particular, diamond has the highest [[Scratch hardness|hardness]] and [[thermal conductivity]] of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools.

Most natural diamonds are formed at high-pressure high-temperature conditions existing at depths of {{convert|140|to|190|sp=us|km}} in the [[Earth mantle]]. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1&nbsp;billion to 3.3&nbsp;billion years (25% to 75% of the [[age of the Earth]]). Diamonds are brought close to the Earth surface through deep [[volcanic eruptions]] by a [[magma]], which cools into [[igneous rock]]s known as [[kimberlite]]s and [[lamproite]]s. Diamonds can also be produced synthetically in a [[HPHT diamond|high-pressure high-temperature]] process which approximately simulates the conditions in the Earth mantle. An alternative, and completely different growth technique is [[chemical vapor deposition]] (CVD). Several non-diamond materials, which include [[cubic zirconia]] and [[silicon carbide]] and are often called [[diamond simulants]], resemble diamond in appearance and many properties. Special [[Gemology|gemological]] techniques have been developed to distinguish natural and [[synthetic diamond]]s and diamond simulants.

}}</ref> Diamonds are thought to have been first recognized and mined in India, where significant [[alluvial deposit]]s of the stone could be found many centuries ago along the rivers [[Penner River|Penner]], [[Krishna River|Krishna]] and [[Godavari River|Godavari]]. Diamonds have been known in India for at least 3,000 years but most likely 6,000 years.<ref name=hershey>
