Carbon is the element from which Diamond is formed. Just pure carbon. Made deep in the Earth.
The hardest substance known (though all diamonds are not equally hard) and rates 10 on the Mohs hardness scale. This is an arbitrary scale. The hardest diamonds come from the NSW fields of Australia, and are in demand as polishing material.
Diamonds also have the highest 'melting point' of the elements - around 3820oK.
They have the highest thermal conductivity -- about 400 times that of copper.
Other allotropes of carbon are charcoal, graphite, and perhaps graphene.

what is the sole element in diamond
The element is carbon.
It's called an elemental mineral, like diamond (crystallized carbon) or gold.
boron
Carbon is the only element necessarily contained in diamond and graphite.

A diamond is absolutely beautiful, even when in the raw. It is a native Element, and the Element that makes up a mineral diamond is carbon.

It isn't the element (carbon) that makes a diamond valuable: it's the availability of the diamond allotrope of carbon, and its limited occurrence on earth.
No, diamond is a form of the pure element carbon.
Carbon, as it forms tetrahedral structure.
unfortunately the only real chemical name for a diamond is Carbon .. makes this tough to send by mail with £2k insurance!
Gold, Diamond
The Hope Diamond glows red after being exposed to ultraviolet light based on impurities in its carbon make-up. You can read more about its red phosphorescence, below.
