Smoky Citrine Tower #13

A powerful, dual-action stone used to manifest desires into physical reality, clear negative energy, and boost confidence

Mohs Hardness: 7
Origin: Brazil, Madagascar, and the United States
A rare, natural variety of quartz combining golden-yellow citrine with smoky, gray-to-black shades, often caused by natural radiation in the earth.

It can be cleaned with warm water and mild soap. It is best to avoid harsh chemicals and high heat, which can affect the color, though the radiation is safe, as it has already decayed.
