Hematite, or haematite, is an iron ore that has the same crystal structure as ruby and sapphire. Hematite is a very distinct gem with a very unique luster.

When cut and polished, its color is shiny and metallic and exhibits the strongest and most reflective luster known as metallic luster. Gemstones with metallic luster have a reflective surface similar to polished metal.
In feng shui practice, hematite is used for its protective force and for its ability to energize its wearer. Overall, hematite is an excellent gemstone for mental, physical and spiritual healing.
