The mineral rutile reveals the secret of rare gemstone crystals.

The mineral rutile, with its unique crystal structure, is considered key to understanding the origin, durability, and value of many gemstones.

Its main component is titanium dioxide. Rutile, with the chemical formula TiO₂, is one of the most important natural sources of titanium. Photo: Pinterest.

It is usually reddish-brown to black in color. The color of rutile varies depending on the presence of iron impurities or other metallic elements. Photo: Pinterest.

It has a metallic luster. The surface of rutile crystals often sparkles, giving it a metallic feel. Photo: Pinterest.

The crystal structure is very distinctive. Rutile often crystallizes into thin needles, long columns, or a cross-linked lattice. Photo: Pinterest.

It appears in many different types of rocks. This mineral is found in igneous, metamorphic, and sedimentary rocks. Photo: Pinterest.

These inclusions often form within gemstones. Rutile "hair-like" inclusions in quartz or sapphire enhance the stone's aesthetic value. Photo: Pinterest.

Rutile plays a crucial role in industry. It is the main raw material for the production of titanium and white titanium pigment used in paints, plastics, and cosmetics. Photo: Pinterest.

Rutile is significant in geological research. It helps determine the temperature and pressure conditions under which rocks formed. Photo: Pinterest.
