How to distinguish natural alexandrite from artificial?

Alexandrite is a very rare variety of the yellow-green mineral chrysoberyl, from which it differs in its unique ability to change color depending on the lighting: under natural light it is green, under an electric lamp it is almost red. The discovery of the stone belongs to N. Nordenskiöld, a Finnish researcher who studied the Ural emerald mines in the 1833th century. When the gem first caught his eye in XNUMX, it was an emerald hue, but in the light of a night candle it turned out to be deep red, which greatly amazed the mineralogist. The find was named Alexandrite in honor of Alexander II, the son of the then reigning Emperor Nicholas I.

The largest known nugget was found in the Urals in the 532th century; its weight was 66 carats. This alexandrite had to be divided into several parts, since it was not possible to sell it due to the incredibly high price. The largest gem known today weighs XNUMX carats. There are also earlier mentions of alexandrite in history, for example, in the Mahabharata, an ancient Indian treatise. The stone was also discovered in a 12th-century burial belonging to a Polovtsian khan – he had a ring with this amazing “chameleon” on his hand.

Place of Birth

The primary deposit of alexandrites is located in the Urals, but it was quickly depleted, although it is the Ural stones that are considered the standard – they are distinguished by a pure emerald hue in daylight and turn red in artificial light. Today, alexandrites are mined from placers in Sri Lanka, Brazil, Kenya, Tasmania, Zimbabwe, the USA, and Madagascar. But most of the gems found there, although they are “chameleons,” are not as beautiful in daylight as the Ural stones. It is interesting that in the Urals alexandrites were always mined together with emeralds, but the miners had a strange superstition about them. Allegedly, if alexandrite was found during excavations, then emeralds would no longer be found, so they tried to ignore the stones, not pick them up or lift them.

Varieties and properties of alexandrite

Formula: Al2BeO4 Color: blue-green, blue-green, olive green, red-violet, purple, pink-raspberry Hardness: 8,5 Density: 3,5–3,84 g/cm3 Transparency: translucent, transparent Cleavage: imperfect Kink: conchoidal The most valuable property of alexandrite is its so-called “Alexandrite effect”, which ensures the variability of the color of the stone under different lighting conditions. It is due to the special structure of the crystal lattice of the gem and the specific arrangement of chromium impurities. There are specimens of this mineral that have opalescence, that is, they can scatter light in such a way that a glare in the form of a “cat’s eye” is formed on the surface.

  • Ural is the best example of color change; it has the deepest and most saturated shades. In daylight it is rich green, in artificial light it is purple.
  • African, Brazilian – green stone with a brown undertone during the day and red in the light of a night lamp.
  • Indian and from Sri Lanka – under different types of lighting it is bluish-green, pinkish or red.

Who is alexandrite suitable for?

On the Internet you can often find references to the fact that alexandrite is considered a widow’s stone. The prerequisites for the emergence of such a sign can be found in the history of our country. The fact is that fashion for it returned in the post-war years, when many men did not return from the front, so they began to say that the gem brings misfortune. But such beliefs are not relevant in the modern world, where alexandrite has been worn by successful people for many years, and the stone costs quite a lot, because there is a huge demand for it.

Ring “Inspirational Motif”

Inspiration is a real miracle that comes into our lives to realize plans, ideas, creative ideas, desires, dreams. And it doesn’t matter what kind of work we do: whether we paint pictures, create fashionable clothing collections or compose music. If we are inspired and passionate about what we do, then success will be guaranteed.

It is precisely these poetic motives that Maxim Demidov jewelers are guided by when creating their masterpieces. They are inspired by the perfection of the rarest gemstones from around the world. Their special passion is gems with unique characteristics and properties, when it seems that nature cannot create anything more amazing.

The rare imperial stone alexandrite has a special advantage: its color changes depending on the light, from green to red. There is even a saying: “In the morning he is an emerald, and in the evening he is a ruby.”

To highlight the wondrous splendor of the 2,37-carat alexandrite in the sensual “Inspirational Motif” ring, the craftsmen encased the Brazilian gem in a slightly muted, laconic platinum base and surrounded it with a sparkling pattern of alternating noble diamonds of various cuts.

Exclusive jewelry with alexandrites are considered one of the most expensive – for all the centuries that the mineral has been known, its price has never dropped, since it is mined only in a few places on the planet. To have such rarity is an extremely powerful inspiration.

Jewelry with precious stones has always been valued among the Russian tsars, and alexandrite had a special attitude, since it is very rare and changes color with different consecrations. Today, almost all natural alexandrites are in private collections or museums; it is almost impossible to find them on the open market. Therefore, you should not take your word for it if a jewelry store offers you a color-changing stone called alexandrite; most likely, it is just synthetic corundum with an alexandrite effect. But is there really no high-quality analogue of an expensive stone?

The synthesis of alexandrite was put into production in the second half of the twentieth century. The very first method of growing laboratory alexandrite was the Czochralski method, but today there is a more effective technology for the production of absolute analogues of this stone – the method of horizontally directed crystallization. Thanks to modern technologies, only experienced experts can distinguish artificial alexandrite from natural one. With 100% similarity to natural crystal, it costs several times less.

Historical information

• Alexandrite was first discovered during the time of Alexander II near Yekaterinburg.
• The first alexandrite was mistaken for an emerald, but upon inspection it turned out that the one found was too hard, and when daylight changed to artificial, the found nugget changed its color and became ruby ​​in color.
• In 1834, alexandrite was presented to the king, in whose honor it received its name: the royal stone – alexandrite.

The main and unique property of alexandrite is its color change depending on the type of lighting:
• When artificial, it has a red-violet hue, which sometimes turns into crimson;
• Daylight causes the stone to transform into a blue-green color, which looks pleasant and mesmerizing.

The variability of color is explained by the presence of trivalent chromium in the composition and some specific features of crystal formation. Chromium ions absorb certain colors, and the crystal lattice changes the wavelength of light, which gives rise to such an amazing color change effect.

Natural alexandrite

Nowadays, the cost of natural alexandrite is incredibly high, this is due to the fact that the natural reserves of this stone are depleted from year to year. Large deposits of alexandrite on earth have been almost completely explored, the largest amount of alexandrite was found in the Urals (Russia), in addition, alexandrite was found in other countries: Brazil, Sri Lanka, Madagascar, Tanzania.

Today, at international shows and jewelry exhibitions, it is very rare to find small stones of faceted natural alexandrite, but even those are immediately sold at auction to private collections. It is also worth paying attention to the price at which the stone is offered. Due to their rarity, alexandrites are extremely expensive – on average from 5 to 37 thousand dollars per carat. Antique items with alexandrite (XVIII–XIX centuries) are of particular value, since most of them were melted down and the prices for surviving specimens are infinitely high.

Thanks to the development of modern technologies, anyone can buy synthetic alexandrite; synthesized stones are absolute analogues of natural ones, and their cost is incomparable with the cost of a natural nugget.

Similarities between synthetic alexandrite and natural

Symbolism of alexandrite

The rare property of the nugget to change color has always had a certain meaning, since at that time there was no explanation for it. Given the great rarity of the stone, many were inclined to attribute various mystical abilities to it.

A change in color was considered by ancestors to be an omen of imminent trouble. In most cases, it could only be worn by rich widows as a sign of the loss or death of a person close to their hearts. In ancient times, such symbolism was assigned to alexandrite after the death of the king.

But today these prejudices are a thing of the past; now everyone reacts differently to changes in the color of the stone. In modern fashion, changing the shade of expensive jewelry is highly valued by jewelry designers. Jewelry houses compare alexandrite with a temperamental, passionate female nature. The blue-green hue shows the depth of female nature, and when alexandrite turns fiery red, the stone becomes a symbol of fiery love and unbridled passion.

When making men’s jewelry with alexandrite inserts, designers put into the jewelry the symbolism of the greatness of the royal stone, attributing to it the wisdom of a statesman, determination and perseverance.
