The word "Diamond" is derived from the ancient Greek meaning "unalterable", "unbreakable" and “untamed". Diamond is the hardest natural substance known to mankind. In mineralogy, Diamond is an allotrope of carbon. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. But a diamond is more known because of its divine beauty once moulded into a perfect shape. Each reflection of the light from its surface proves its worth. It surely is a symbol of Love and rarity.
