The birthstone for April is the diamond, a stunning stone, with a simple composition, that has few weaknesses and many strengths. It has a unique ability to reflect and refract light. The diamond is a crystallized carbon, formed deep within the earth and is harder than any other substance. The diamond is four times harder than the next hardest mineral, corundum (The sapphire and ruby are examples .) This does not mean the stone cannot be damaged. It has perfect cleavage, which means there are four directions of cleavage, so a strong hit can split the stone. Diamonds have a broad color range, including yellow, red, pink, blue, and green.
