Embrace Your Birthstone
A birthstone is a stone that correlates with a specific month of the year.
This means that depending on when you are born, a specific birthstone is assigned to you based on the month and the colour that characterises this month.
Wearing your birthstone is said to give you healing powers, and if you want to optimize the healing powers, you should preferably alter the stone each month.
