Natural Citrine is quite rare to find in nature. An extremely high percentage of all Citrine sold is actually either Amethyst or Smoky Quartz that has been heat treated by man. It took us awhile to stock Citrine, as we are known for all our products being natural. Citrine is an exception, as over time i felt drawn to it, it has been my go to every morning when i manifest & start my day. It is a natural gemstone, but man has heated her up, to give her the Citrine coloring. At times we do come across natural Citrine, but not often. Personal choice at the end of the day.
