A simulated alexandrite stone changes color as the source of light changes, green in the daylight to red in incandescent light.
Alexandrite is known for its unique ability to change its color from emerald green to burgundy-red, depending on the nature of the lighting. The history of this mineral is also unusual, like its properties. According to the officially adopted version, for the first time the gem was discovered in 1833 in the Ural emerald mines and was presented to the general public in April 1834 on the day of majority of the future sovereign of Russian Alexander II. In honor of the Crown Prince, the stone was given such a beautiful name. Already, being the emperor, Alexander 2 wore, without taking off, a ring with alexandrite as a personal talisman, due to what this Uralic gem also began to be called "imperial stone". At the Soviet authorities alexandrite also enjoyed special reverence. Jewelry with him was banned for sale, and the fate of each individual stone was closely monitored. Today, Alexandrite is considered one of the rarest and most beautiful gemstones. Some of its specimens are valued more expensive than diamonds. Types and colors of alexandrite Alexandrite belongs to the species of chrysoberyl. Its chemical composition is unique. In addition to iron and titanium, this stone contains chromium, the ions of which cause an impressive change in color, called a color reversal for gemologists. In some cases, the process of color change is also affected by the vanadium contained in the mineral. Alexandrite is transparent, but very rarely it is colorless. Its most common color is bluish-green. Less common is olive with shades of yellow and brown scales. Stones extracted from different deposits can differ significantly in the color palette. Ural alexandrite, which is rightly considered a model of beauty, has a bluish-green coloring in daylight, and with artificial - a crimson or purple-red color. Gems from Africa or Brazil in the day painted in brownish-greenish colors, and with artificial lighting can be several tones redder than the Ural stone. Alexandrite from the island of Sri Lanka under the bright rays of the sun resembles the color of the Urals minerals, and in the evening lighting becomes purple. In the depth of the color reversal, the Urals alexandrites are leading. Deposits, mining of stone A radical deposit of alexandrite is considered to be the Ural emerald mines. At present, their reserves are almost depleted, and stone mining operations are not being conducted. The deposit of fairly large crystals was discovered in Brazil in the 1980s, but this mine was fully developed within three months, after which the finds of the precious stone acquired an episodic character. Today, Sri Lanka is considered the largest supplier of alexandrite to the world market. Mining is also carried out in Thailand, India, Tanzania and Madagascar. Experts admit that none of the stones mined in these deposits can match the perfect beauty of the Urals gem. Back to the table of contents How much does the stone alexandrite (natural and artificial) The price of alexandrites depends on their color, the depth of the color reversal (alexandrite effect), the degree of purity and weight.

The color reversal in them can be expressed even more strongly than in natural alexandrites.
