Alexandrite is the colour change variety of the chrysoberyl crystal and it's the birthstone for the month of June. These rare gemstones are highly coveted as they change colour depending on the source of light that they are exposed to. Alex gems are commonly bluish green in daylight or cool lights and, pinkish red in incandescent or warm lights.
These exclusive gems are also known as the emperor gemstone which is emerald by day and ruby by night. This gemstone is very unique and really hard to find therefore it may demand really high prices; especially when the gems are over one-carat size.

The color-changing property of alexandrites (Colour-chance Chrysoberyl), known as the alexandrite effect, occurs because of how the gemstone absorbs and reflects light. The stone typically exhibits a vibrant green hue under daylight or lighting conditions with a color temperature of around 5000K. However, when viewed under warmer light sources like an incandescent light, around 2500K, it shifts to shades of brown, red or purplish-red.
In real-world scenarios, lighting is rarely constant or from a single source. Most environments combine various types of light—natural daylight, LED, fluorescent, or incandescent—leading to a blend of the gemstone's colors. This dynamic interplay of light makes alexandrites appear different throughout the day and in various settings.
