This striking colour change is a result of the interplay between chromium and iron impurities within the crystal lattice.

Properties of Alexandrite

What Gives Alexandrite its Colour Change?

The stunning colour change in alexandrite is primarily due to the presence of chromium ions in its crystal structure. In natural daylight, these ions absorb certain wavelengths of light, resulting in a greenish-blue appearance. Under incandescent light, the chromium ions react differently, creating a vivid purplish-red hue.

What are the Different Colors that Alexandrite Can Change To?

Alexandrite’s colour change typically ranges from green or bluish-green in daylight to purplish-red or reddish-brown under incandescent light. The intensity of these colours can vary, with the most highly prized stones exhibiting a strong contrast between the green and red hues.

What are the Different Types of Alexandrite?

Alexandrite can be categorized into three main types based on its origin:

  1. Russian Alexandrite: Mined in Russia’s historic Ural Mountains, these are the most prized and valuable Alexandrite gems.
  2. Brazilian Alexandrite: Found in Brazil, this type often has a softer colour change and is more readily available than Russian alexandrite.
  3. Synthetic Alexandrite: Lab-grown alexandrite exhibits the same color-changing properties as natural alexandrite but is more affordable and accessible.
