How to distinguish synthetic sapphire from natural?

Sapphire is a gemstone with a rich palette of shades: blue, orange, pink-orange, pink, green, yellow and other colors. At the same time, the most valuable and desirable are cornflower blue sapphires. Chemically, this stone is aluminum oxide, which acquires bright blue colors due to impurities of titanium and iron. Iron alone (without titanium) will make the stone greenish, and the presence of vanadium in the composition will give the sapphire a purple tint.

Did you know that sapphire and ruby ​​have the same chemical formula and are both varieties of the mineral corundum? The difference between the stones is in color: ruby ​​(due to the presence of chromium in the composition) is painted lilac-red, while sapphire can have any color except ruby.

Properties of natural sapphire

Mohs hardness: 9 Density: 3,95-4,00 g / cm³ Shine: glass Refractive index: 1,766-1,774 Birefringence: 0,008 Color: blue, pink, orange, yellow, green, purple, black Syngonia: trigonal Cleavage: no Sapphires also come in different colors, for example, blue-green, yellow-blue, gray-blue. Such specimens are valued less than homogeneous blue minerals, but there are multicolored sapphires that reveal amazing sides thanks to jewelry cutting. The work of a master and the fabulous shimmer of the stone significantly increase its value. Real sapphires wait for thousands of years in natural conditions, in the bowels of the earth, for their birth. They are mined in India, Sri Lanka, Thailand, the USA and Australia, as well as in other countries of the world. Considered especially unique star sapphires effect sapphires asterism.

Asterism – This is a phenomenon in which a hexagonal star pattern appears on stones under certain lighting conditions. The phenomenon is due to the presence of needle-shaped inclusions in sapphire, due to which light passes through the crystal in a specific way – in the shape of a star.

Artificial or synthetic sapphire

If natural sapphires are mined from the depths of the earth, then artificial ones are created in the laboratory in literally a month or two, depending on the size of the future mineral. The first artificial sapphires were created by the French chemist Auguste Verneuil in 1904. He discovered the technology of droplet deposition in an oxygen-hydrogen flame, during which synthetic sapphires are formed. Today this method is simply called the Verneuil method. Most often, colorless (white) sapphires are produced this way, which are used in medicine and technology, where durable and transparent materials are required. The resulting stones are chemically identical to natural sapphires, so they cannot be called a fake. However, such sapphires have no investment value, and their origin will always be obvious to an experienced jeweler.

How to distinguish a sapphire from a fake

The easiest way to determine the authenticity of a sapphire is with the asterism effect, which is rarely faked with high quality. When a natural stone is rotated, the star will change its position, but in a fake it will remain in place.

You can distinguish between fake, synthetic and natural stone using one tricky method that gemologists or chemists can handle. The specialist needs to immerse the stone in a special liquid called monobromonaphthalene. When examining the mineral through a transparent container with monobromonaphthalene, you can easily see the special stripes inside the crystal. If they are straight, the stone is real; if they are curved, it is fake or synthetic.

  • kyanite;
  • tanzanite;
  • tourmaline;
  • spinel.

Using a magnifying glass

Special preparation is not always required to detect a fake. For example, you can determine the authenticity of a sapphire yourself using a magnifying glass.

Through a magnifying glass, you should see inclusions and impurities inside the stone, which will be evidence of its natural origin. There are the least foreign bodies inside artificial stones. In addition, synthetics will produce gas bubbles inside, which can be grouped or located separately.

Also inspect the surface of the stone for the presence of glues; there should be no even stripes on it, otherwise you will see a doublet or triplet – a sapphire formed by gluing two or three parts of the stone together. This method could use glass, artificial stones, or parts of two different sapphires.

With a refractometer

A refractometer can be used to professionally check stones for authenticity.

Refractometer – a device that measures the degree of refraction of light in stones. Knowing the necessary indicators, it is easy to establish the authenticity of the mineral. For example, for sapphires the refractive index has values ​​of 1,762 – 1,778. A deviation of even 0,1 will indicate that the expert is not looking at a sapphire.

Cost of natural sapphires

As a rule, the origin of stones is eloquently stated by their price. First-class natural sapphires can cost between $1 and $000 per carat. Artificial ones are always cheaper than natural ones, except in those cases when they try to pass off synthetics as natural gems.

Imitations of gems, doublets and triplets, also cost several times less. But you should be wary of scammers and purchase stones only in specialized and well-known boutiques.

You can choose certified jewelry with 100% natural sapphires in the catalog of the Maxim Demidov jewelry house.

Prohibited verification methods

To check the authenticity of stones, contact specialists who will do it quickly and safely for your jewelry. Never follow advice from the Internet, such as those who suggest running sandpaper over the sapphire or testing it for hardness using another mineral. You will most likely leave unsightly scratches even on a natural crystal.

This gemstone is invariably mentioned among the most famous and coveted. And, of course, it is associated with the blue color, so beloved by writers and artists. But the ancient name conceals something more, revealing a truly incredible story.

From the point of view of mineralogy, sapphire is a stone related to corundum. Its composition is dominated by aluminum oxide, and the color is created by impurities of titanium, iron, chromium, and vanadium. Deposits have been found in placers and pegmatites throughout the world. The most valuable are sapphires from Indian Kashmir, Myanmar, and Sri Lanka. Mining also continues in Madagascar, the USA, Australia, China, Tanzania and in small pockets of blue corundum in other countries.

Varieties of sapphire

Geologists classify only blue stones as sapphires, but their related origin brings them closer to their colored neighbors. It is the light shades that beautifully refract the rays of light that are valued. They are cut into different shapes or given a cabochon shape.

Jewelry sapphire can be yellow, pink-orange, green and even colorless. A special place is occupied by stones with the effect of a shining star. In science, this phenomenon is called asterism, and not every gem is able to manifest it during processing.

Modern technologies make it possible to produce artificial transparent sapphires – leucosapphires. Due to their high strength, they are used in the space and aviation industries as part of windows and glass. The transparency of synthetic minerals is valued in ophthalmology. And even phone screens often contain sapphires of industrial origin.

Blue sapphire is not much inferior in strength to diamond. It has a high melting point, so the stone is not afraid of external influences. The chemical composition is very similar to the formula of ruby, but the quality of the stone can be distorted due to inclusions and impurities.

The rich color palette of jewelry sapphires gave rise to even more legends about properties of rare gems. Therefore, blue stone is considered a symbol of love and is often used in engagement rings. Pink sapphire has the power to fulfill wishes, but is sensitive to the negative emotions of the owner. The green tint of the mineral enhances alertness and visual acuity. Yellow sapphire is considered one of the most powerful amulets; it is recommended to wear it only on special occasions. Very dark stones, which appear black to the naked eye, can have magical properties and protect against envy and dark thoughts.

There are no restrictions for men’s and women’s sapphire jewelry. And even different types of appearance look advantageous with blue stones. Only when selecting rarer shades is it worth determining your color type.

How to distinguish natural sapphire from a fake

  1. Price. First of all, you should pay attention to the price. A real gemstone cannot be temptingly cheap.
  2. Structure. Sometimes synthetic analogues are used, but they are produced by gas bubbles in the structure of the mineral.
  3. Ultraviolet testing. If the jewelry actually contains sapphire, the natural stone will glow white under the influence of an ultraviolet lamp. Counterfeits do not pass inspection; they are indicated by a green glow.
  4. Another clue could be high hardness natural gemstone.
  5. Check by professionals. For complex products, it is not easy to examine the insert from all sides. You will need the help of a professional jeweler who has experience in determining the authenticity of stones. Even instruments make mistakes if unscrupulous manufacturers combine corundum and pieces of colored glass in one frame.

Therefore, sapphires should be selected with special care and only at specialized points of sale.
