Find out more about the Alexandrite, one of the most valuable and rare stones in the world!

The gemstone industry is vast. So date, approximately 300 distinct kinds of gemstones have been identified. You may be familiar with the ruby, emerald, and, of course, the diamond, but there are more gemstones you may not be aware of. Many of them are quite uncommon, and in this article, we will highlight one of the most rare of them all: Real Alexandrite Stone.

What is Real Alexandrite?

Real Alexandrite, also called as chrysoberyl by researchers, is a gemstone that changes color depending on the light. Alexandrite is made up of two minerals: chromium and beryllium. Both minerals are required for the formation of chrysoberyl. The stone was discovered in Russia's Ural Mountains about 1830. The unique green hue that varies in the light made this gemstone stand out.

What are the characteristics of Real Alexandrite Stone?

The most well-known feature of Alexandrite is its ability to change color. The fundamental hues are green and red; the stone is green in daylight and sunshine and turns red when illuminated by an electric light bulb. When the stone is put in other light sources, it reflects other hues as well.

• Changing color of alexandrite under different lights

Real Alexandrite Stone is often mined in tiny pieces. The majority of stones are tiny and weigh less than one carat (0.2 grams). The biggest alexandrite ever discovered is a 65.7-carat stone from Sri Lanka, and the largest alexandrite found in the Ural Mountains weighs over 30 carats.

What determines the value of alexandrite?

• The intensity of the color

The value of a Real Alexandrite Stone, like that of a diamond, is influenced by a number of factors (4Cs for diamonds). The colour, and especially the intensity, is the most essential factor for determining the value of alexandrite. The greater the value, the deeper and more vivid the color.

• The percentage of color change

The hue of the color, on the other hand, does not always have a direct impact on the value of the Real Alexandrite Stone. The color can indicate where the alexandrite was mined; we'll get to that in a moment. The degree of color change is the second criteria. Not only must the colors red and green be vibrant, but so must the color change. Alexandrite, in reality, has a wide spectrum of color alterations, ranging from 5% to 100%.

• The clarity

The clarity of the stone is the next criteria. Real Alexandrite, like other gemstones, is not necessarily loupe-pure. However, it is worth noting that clarity is not a priority in assessing the value of Real Alexandrite. Color intensity and color change are the criteria that take precedence.

This means that a Real Alexandrite with vivid colors and opaqueness is more valuable than a light-colored alexandrite that is loupe pure. This is not to say that clarity isn't crucial in assessing value. A brilliantly colored alexandrite that is likewise immaculate is clearly in the top tier! Unfortunately, these types are becoming even more scarce.
