An iceberg is comprised of water molecules that combine under extreme conditions to form an ice pack which can then break into icebergs. But an iceberg is not water, an iceberg is comprised of water molecules. In this way a diamond is comprised of carbon. The element is carbon and the diamond is an object formed of that element.

It is both a mineral & element.
