Alexandrite Gemstone Origin

Alexandrite gemstones are a rare and valuable type of chrysoberyl that is known for their remarkable color-changing property. These precious gemstones were first discovered in the Ural Mountains of Russia in the 1830s, and since then, they have been found in other countries, including Brazil, Sri Lanka, and Tanzania.

The unique geological conditions where Alexandrite gemstones are formed play a significant role in their beauty and value. These gemstones are created when beryllium, aluminum, and silicon-rich rocks undergo a metamorphic process. During this process, high pressure and temperature cause tiny trace elements such as chromium and iron to be incorporated, which is responsible for the color-changing effect.

The primary source of Alexandrite gemstones is Russia, which produces a small quantity of fine quality stones. However, some of the most exceptional Alexandrite gemstones have been found in other locations, such as Brazil's Minas Gerais and Sri Lanka's Ratnapura mines.

Tanzania Merelani Hills Small quantity of low-quality stones

As you can see from the table, Brazil is the largest producer of Alexandrite gemstones, with a significant quantity of high-quality stones, followed by Russia and Sri Lanka.

Alexandrite Gemstone Color Change

Alexandrite gemstones are renowned for their unique color-changing property, which results from a rare combination of minerals in their composition. Under natural light sources, such as the sun, these stones exhibit a vivid green color. However, under artificial light sources, such as incandescent lights, they showcase shades of red and purple. This remarkable phenomenon is known as the alexandrite effect and is highly sought after by gemstone collectors and enthusiasts.

The color change effect is due to the presence of chromium in the crystal structure of Alexandrite. When exposed to different light sources, the chromium atoms in the crystal lattice absorb different amounts of light and cause the gemstone to exhibit different colors, creating a mesmerizing visual experience.

Alexandrite Gemstone Color Change Examples

Light Source Color Displayed
Sunlight Green to bluish-green
Incandescent light Red to purplish-red
Candlelight Red to orange-red
LED light Green to bluish-green or purple

If you are looking to invest in an Alexandrite gemstone, it is essential to understand and appreciate the color-changing property that makes this gemstone so unique and valuable. Ensure that you view the gemstone under different lighting sources to fully appreciate its beauty and rarity.

Alexandrite Gemstone Value

Alexandrite gemstones are known for their rarity, beauty, and unique color-changing properties. With a limited supply and high demand, the value of Alexandrite gemstones can vary greatly depending on numerous factors. Some of the main factors that contribute to the value and the Alexandrite gemstone price include color, clarity, size, and origin.

The most valuable Alexandrite gemstones are those that exhibit a distinct and vivid green color in daylight, and a rich red or purple hue under artificial lighting. The intensity of the color change is a significant factor in determining the value of the gemstone.

The clarity of the stone is also a crucial factor. The best Alexandrite gemstones are free of visible inclusions or blemishes, which can impact the gemstone's clarity and reduce its value.

The size of the Alexandrite gemstone also affects its value. Larger gemstones are generally rarer and more valuable than smaller ones. However, the consistency of the color change and quality of the gemstone's cut may also influence the final value and pricing.

Finally, the origin of the Alexandrite gemstone can also influence its price. Alexandrite gemstones sourced from the original discovery location in Russia are often more valuable due to their rarity and historical significance.

When purchasing an Alexandrite gemstone, it is essential to consider all these factors to determine its true value and price. Always buy from reputable dealers and insist on a certificate of authenticity to ensure you get the best value for your investment.
