What is an Amethyst and why is it purple?

Amethyst is more than just a pretty gemstone—it's a violet variety of quartz, a common and tough mineral made of silicon dioxide (SiO₂). But what makes it stand out is its vibrant purple hue, which can range from soft lavender to deep violet.
That color comes from tiny traces of iron inside the crystal. Over time, natural radiation from the Earth changes how that iron interacts with the quartz, turning it purple—a kind of deep underground magic!
Amethyst often forms in geodes, which are plain-looking rocks that hide hollow spaces lined with sparkling crystals. These geodes usually appear in volcanic rock.
Used in jewelry for centuries, amethyst was once believed by the Greeks to prevent drunkenness. Today, it's still treasured for its beauty, and it’s also the birthstone for February.
