What are Natural Colour Changing Sapphires?

Natural colour changing sapphires, also known as color-change sapphires, are a variety of corundum, the same mineral that forms rubies. These sapphires exhibit a phenomenon called pleochroism, which means they can display different colors when viewed from different angles or under varying lighting conditions. The most common color change is from blue in daylight or fluorescent light to purple or violet under incandescent light.

What Causes the Color Change?

The color change in natural colour changing sapphires is due to the presence of trace elements in the crystal lattice of the gemstone. The two main elements responsible for the color change are vanadium and chromium. Vanadium causes the sapphire to appear blue, while chromium gives it a pink or purple hue. The balance between these elements determines the color change effect.
