These are natural Citrine Towers from Zambia and Madagascar. They are not heated treated amethyst and this is why its more expensive than some you will see.
They are quirky in that they do not polish until imperfections are removed. There can be natural indentations. Enjoy the photos showing great clarity, colour and life. The right one has a cute hematite red spot and indentation. Left seems fully polished.
Use it bring out your sunny side with its ability to cleanse your energy and to help build self-confidence, self-esteem and self worth. This is why I believe it works to help attract abundance into your life.
Dimensions are for the left and use my hand as a guide. These natural citrine towers are also called a prism, obelisk or generator, and the shape also has properties.
