April Birthstone: Diamonds.

Each of the twelve calendar months has a gemstone associated with it. The origin of birthstones is believed to date back to the breastplate of Aaron which contained twelve gems representing the tribes of Israel. The current list dates back to 1912 with the except of Tanzanite having been added to December.

Diamonds are the gemstone associated with April.

Diamonds can be harvested from the earth or produced under extreme heat and pressure in a laboratory (though few exist in the world). Though they are considered to be rare, they are actually not as rare in nature as gem quality corundum (sapphires and rubies).

Diamonds are the hardest substance created by nature and have a rating of 10 on the Mohs scale of mineral hardness. They are 4 times harder than corundum, which has a 9-9.5 Mohs rating.

Today, diamonds can be found in a rainbow of colors including yellows, greens, blues, purples and pinks. White or colorless diamonds are more common and therefore less expensive than colored diamonds. When referring to lab-created diamonds, the opposite is true.

Conscious consumers are staying away from diamonds more and more because of the long history of social impact associated with them. However, ethically sourced diamonds are available. You no longer need to sacrifice beauty for your values.
