1. Introduction to Alexandrite: Nature's Magic Trick
Imagine a gemstone that looks green during the day and turns red at night - that's alexandrite! This amazing color-changing ability is what makes alexandrite so unique and valuable. First discovered in Russia's Ural Mountains in the 1830s, alexandrite was named after the future Czar Alexander II.
Alexandrite is actually a variety of the mineral chrysoberyl. What makes it special is the presence of chromium, which causes the stone to absorb and reflect different colors of light. In daylight or fluorescent light, alexandrite appears green or bluish-green. But under incandescent light (like candlelight or a light bulb), it transforms to a purplish-red color!

2. The Science Behind Alexandrite's Color Change
So how does alexandrite pull off this amazing color-changing trick? It's all thanks to the way the stone absorbs and reflects light. Alexandrite contains traces of chromium, which is the same element that gives rubies their red color. In alexandrite, the chromium causes the stone to strongly absorb yellow and blue light.
In daylight, which contains all colors of the spectrum, we see more green light reflected from the stone. But in incandescent light, which has more red wavelengths, we see the stone reflecting more red. This is why alexandrite can look like two completely different gemstones depending on the lighting!
The phenomenon is known as the "alexandrite effect" and is so unique that it has become a benchmark for other color-changing gems. The stronger and more dramatic the color change, the more valuable the alexandrite is considered to be.

This beautiful alexandrite engagement ring is a perfect example of how the stone can look different in various lights. It's like getting two rings in one!
3. Rarity and Value: Why Alexandrite is So Precious
Alexandrite is considered one of the rarest gemstones in the world. It's even rarer than diamonds! This is because alexandrite needs very specific conditions to form. It requires the presence of beryllium (which is rare in the Earth's crust) and chromium (which usually occurs in different environments than beryllium). Finding these elements together is extremely uncommon.
The rarity of alexandrite makes it very valuable. High-quality natural alexandrite can cost anywhere from $50,000 to $70,000 per carat! The most valuable alexandrites are those that show a complete color change from green to red, with vivid colors in both lights.
Factors that affect the value of alexandrite include:
- Color change: The more dramatic and complete the color change, the more valuable the stone.
- Clarity: Like most gemstones, clearer alexandrites are more valuable.
- Size: Large alexandrites are extremely rare, making them very expensive.
- Origin: Russian alexandrites are often considered the most valuable due to their history and quality.

This stunning alexandrite ring showcases the gem's beauty and rarity. It's a treasure that will be cherished for generations.
4. Natural vs. Lab-Created Alexandrite: Making an Informed Choice
Because natural alexandrite is so rare and expensive, scientists have found ways to create alexandrite in laboratories. Lab-created alexandrite has the same chemical and physical properties as natural alexandrite, including the color-change effect. The main difference is that lab-created stones are much more affordable and available in larger sizes.
Here's a quick comparison of natural and lab-created alexandrite:

5. Alexandrite as the June Birthstone: A Modern Twist on Tradition

Alexandrite is also the traditional gift for the 55th wedding anniversary. Its color-changing nature is said to represent the many changes a couple goes through in their years together.
