Citrine

Citrine is the birthstone for the month of November.

Fun Fact… Citrine is formed when Amethyst heats up to nearly 1000 Degrees Celsius

So, Amethyst forms in a dormant volcanic area and new volcanic activity causes it to become Citrine. When that transformation is incomplete we get Ametrine.
Citrine is known as the merchant’s stone, drawing abundance and helps one to increase their personal power. Other attributes include bringing happiness to the wearer and builds confidence and willpower.
