Alexandrite is the highly regarded color changing variety of Chrysoberyl. The color of Alexandrite changes under different lighting conditions.

If viewed in daylight, its color is greenish blue to dark yellow-green. If viewed in incandescent or candle light, its color is pink to red.

Alexandrite is a very rare and highly valuable gemstone, and until recently was extremely difficult to obtain due to its rarity.

However, new sources in Brazil and Tanzania have made this gemstone available and more mainstream on the gemstone market.

Alexandrite was first discovered in Russia in the early 1800's.

It was named in honor of Alexandar Nicholavich, who was later to become the Russian Czar Alexander II.

Legend has it that the gemstone was discovered on the future Czar's birthday and named in his honor, though the factual nature of this is disputed.

The colors within alexandrite are due to trace amounts of the mineral impurities iron, titanium, and chromium (and rarely vanadium is also present).

As is the case with emerald, the chromium element both giveth and taketh away.

While chromium is responsible both for the green color as well as the color change characteristics of alexandrite, chromium also causes alexandrite (like emerald and ruby) to be characterized by fissures and fractures within the gemstone.

Just as emerald is treated under high pressure with oil, in recent years newly-mined alexandrite has oftentimes similarly treated under high pressure with a fluxing agent such as resin, wax, or borax

The most desirable colors of Alexandrite are those that show a clearly visible pure hue color change, such as a pure green/blue in daylight to a pure red in incandescent light.

In addition to its color-changing habit, Alexandrite is a pleochroic gem, showing different color intensity when viewed at different angles.

This factor must be taken into account when cutting Alexandrite gemstones.

Alexandrite exhibiting chatoyancy does exist but is very rare, thus Alexandrite Cat's eye is rarely available.

Alexandrite is a rare and exquisite gemstone with outstanding color changing properties, and is most often faceted into round and cushion cuts that can bring out the best in its color.

In jewelry, Alexandrite is used as rings and pendant centerpieces.

Alexandrite in large sizes is extremely rare and valuable

most Alexandrite available is 2 carats or less.







Mohs Hardness - 6.5-7
Found in - Sri Lanka, Cambodia, Thailand, France, Norway, Tanzania and Australia.

  Zircon name was probably derived from the Arabic zar (gold) and gun (color).

It is found in Igneous rocks and comes in a variety of colors.

The colorless stones closely resemble diamonds, but impurities will produce stones of yellow orange, blue, red, brown, and green.

It may be distinguished from diamond by its double refraction and by wear and tear on its facet edges.

When first removed from the water, crystals are dull, but take on brilliance after cutting.

Blue zircon is most sought after as a gemstone, and many of the more common varieties are heated to turn them blue.

It is a source of two rare metals, ziranium and hafnium which are used today in nuclear reactors.

Zircon is an important gemstone of many colors, and is an historical gemstone used for thousands of years.

It is sometimes looked upon as a cheap Diamond simulant, but in actuality it can be a valuable gem

. Its color diversity is caused by traces of certain impurities, some of which are radioactive.

Zircon gemstones containing radioactive element traces undergo a process called metamiction, in which their inner crystal structure becomes destroyed.

These radioactive forms of Zircon must be heated to stabilize them for use as gems.

In fact, many of the gem forms of zircon (even those that are not radioactive) are heat treated to enhance color and increase transparency.

The radioactivity in Zircon gemstones is very minimal and is generally believed to be safe, without posing any health hazards.

Zircon comes closer to resembling Diamond than any other natural gem.

Its strong luster and intense fire gives it a real sparkle that is comparable to Diamond.

However, its popularity is somewhat diminished by the fact that it is often perceived as an inexpensive Diamond imitation.

Colorless Zircon is easily distinguished from Diamond by its strong double refraction and lower hardness.

The brilliant luster and fire of Zircon, combined with its good hardness and range of colors, make it a most desirable gem.

However, it does have some undesirable traits.

An interesting and strange habit exhibited in only few Zircons is that their color darkens and their luster dulls upon prolonged exposure to sunlight.

This effect can be reversed by giving the stones a second heat treatment.

Zircon is also prone to cracking and chipping if banged too hard.

For this reason, care must also be taken when faceting Zircon gemstones.

Another important factor when faceting Zircon is to minimize the appearance of its strong double refraction by cutting along proper angles. Zircons that are not faceted propely can appear blurry, due to strong double refraction.

Zircon is sometimes confused with Cubic Zirconia.

Cubic Zirconia, a synthetic, inexpensive Diamond simulant, resembles colorless Zircon and has a similar sounding name.

However, the two are entirely separate substances, and have no connection with each other except for the fact that they both contain the element zirconium in their chemical structure.

Zircon of all colors are used as gems, but blue, golden-brown, and white are the colors most often used.

Blue Zircon, the most popular color, has a lively pastel blue, and occasionally has a very desirable striking bright blue color.

Colorless Zircon is usually cut with a brilliant cut to bring out its fire to its fullest capability.

It is often used as a cheaper, yet natural alternative to Diamond.

The other color forms (yellow, green, pink, and purple) are less often seen in jewelry.

Zircon is the traditional birthstone for December.


Metaphysical :

In Middle Ages it was worn by travelers as an amulet for protection from sickness, injury and insomnia.

It was believed to provide the wearer with wisdom, honor, and riches, and loss of luster is said to warn of danger.

According to legend, Zircon is the stone of Venus and kindles a fire in the heart of its wearer.

According to fable, the Zircon makes it's wearer so favored that all his ventures thrived.

In modern times, it is thought to help the liver, asthma, lung problems, and stimulate metabolism.

It is also said to symbolize healing and help the wearer overcome losses, heal mental disturbances and promote common sense






How To Test Amber

Amber will always smell of resin / pine forest.

Polyester and plastic will smell very unpleasant, think of a burning plastic bag.

Odour test: Heat a needle much, and let the tip burn in a place where it cannot be seen, for example. through a bore hole. Is it true, the pleasant smell of resin / pine forest.

Plastic and polyester smells like burned plastic.

Celluloid smells slightly of camphor.

Casein smell of burnt milk.

Cut in one piece with a knife, the amber MUSL fracture, as glass or flint, not a nice interface.

Plastic has a much nicer interface.

Salt water sample in a glass of plain water, plastic floaters, but amber and polyester sink.

In a concentrated saline amber floats up, but polyester and Bakelite sink.

It is simply an examination of the density.

The disadvantages of this method is mainly that if amber example. fitted with a slvsken would its density be changed so much that it sinks into the salt solution; and pressed amber can also sink to the bottom.

Other things that can be mistaken for amber is brown glass jewelry and the ruddy agate type carnelian, this is much heavier and harder than amber.

Old jewelry of horns can have a very high similarity with amber, but is slightly heavier and the smell test, it smells very unpleasant of burnt hair
