Gorgeous!

beautiful - Not_A_Weeaboo

Red is the rarest diamond color in the world and Red Diamond is the most expensive gemstone ever ($1,000,000 per carat).
The source of their red color is debated but it's commonly accepted that "during the diamond’s formation, a plastic deformation is caused in the crystal lattice structure. Some of the atoms are misplaced as the diamond moves up through its kimberlite deposit, and the intense pressure of this movement causes the varying shades of pink, or red, to appear."- wiki - Metal_Treasure
