Hematite is a naturally occurring iron oxide mineral that has a dark steel gray color.  
Hematite is generally colored black-steel or silver-gray but can also be found naturally in variations of red and brown. Many times you will find this stone has been electroplated, which is a way of using an electrical current to bind other trace metals to the surface of the stone. This can transform Hematite into many bright colors! Depending on the color or finish of your Hematite beads, they can complement a wide variety of jewelry designs.
This stone is commonly found in places that have mineral hot springs, but it can also form in volcanic areas. Hematite has been found all over the globe, from South Africa to the shores of Lake Superior in Canada. 
Hematite is believed to hold metaphysical properties that absorb negative energy and aid in processing grief. This stone was especially popular as mourning jewelry during the Victorian Era. Hematite is used in gemstone healing to absorb negative energy and to release mental and physical tension in times of stress or worry.
