What does a tourmaline gemstone look like?

Tourmaline is a fairly common mineral, but stones suitable for jewelry production are rare. Tourmalines are very beautiful, they surpass all other precious stones in the variety of colors and shades. The mineral has a bright glass luster. It is highly valued by jewelers, as it is capable of imparting sophisticated brightness, shine and play to jewelry. Tourmaline lends itself well to processing; it is a fairly hard mineral, but if worn carelessly it can wear out. The stone has the property of shimmering in the light, changing its hue depending on the lighting. There are polychrome (multi-color) tourmalines, with a sharp transition of colors. Tourmaline appeared in Europe only in 1703, thanks to Dutch sailors who brought it from the island of Ceylon. Jewelry with tourmaline did not immediately gain popularity, which cannot be said about Russia, where this mineral was discovered much earlier. Presumably, it was brought from India, where it has been used since ancient times. Tourmaline was used to decorate church utensils, icons, royal crowns, caskets and royal outfits. The famous tourmalines are the bunch of grapes of Catherine II, which was presented to her by the Swedish king Gustav VIII, as well as the red tourmaline that adorns the crown of the Czech kings, which was considered a ruby ​​for a long time. Varieties of tourmaline have their own names:

  • • Rose-red and pink tourmalines, similar in color to ripe raspberries, are considered the most valuable; they are called rubellites, for their high similarity to rubies.
  • • Yellow manganese stones are tsilaisites.
  • • Green – verdelites, emerald-green gems are especially valued.
  • • Achroites are colorless, transparent stones, with a bluish or pink tint, they are extremely rare, extremely beautiful and mysterious.
  • • Red-violet, crimson, cherry and lilac-red stones are called sibirites.
  • • Transparent violet and blue indigolites are highly prized.
  • • There are yellow and dark brown varieties called dravites.
  • • Watermelon tourmalines have a red core and a green border, or vice versa. There are light-colored crystals with a black or red head.
  • • A special place is occupied by black opaque tourmaline – schorl. It adds mystery and mysticism to jewelry.
  • • The rarest and most incredibly beautiful neon blue tourmaline is Paraiba.

The most famous tourmaline deposits are located in Sri Lanka, Brazil, Australia, India, and Afghanistan. In Russia, stone mining is carried out in the Urals and Transbaikalia

Paraiba is a rare variety of tourmaline, one of the most expensive jewelry stones on the world market. The gem was first discovered in 1987 in Brazil. The stone received its exotic name from the state of Paraiba, where it was found.

Tourmaline has a blue or bluish-green hue with a neon glow. This is a color effect that has nothing to do with luminescence. Stones with a rich, concentrated neon blue color are especially prized.

Characteristics and properties of stone

Paraiba tourmalines are characterized by gas-liquid inclusions, veils and fractures. Such stones are called “sugar” paraiba. Specimens with a high degree of purity are absolutely unique and are in a much higher price segment.

This gem is quite fragile, which certainly affects the cutting process and ultimately the size and weight. In order to reveal the magnificent natural qualities of Paraiba, to emphasize the play of extraordinary color and radiant purity, to correctly build proportions and symmetry, cutters have to sacrifice a large amount of precious material. High-quality cut stones, as a rule, have lower carat values ​​and higher costs.

Almost all Paraiba tourmalines are refined by heating. In this case, it is acceptable and does not reduce the dignity of the stone. It is usually impossible to determine traces of it even in laboratory conditions, therefore the certificates indicate that “tourmalines are often subjected to heat treatment.” At the same time, the price for heated and unheated stones is practically the same.

When assessing the value of a stone, its origin plays an important role. If Brazil is indicated in the Origin section of the Paraiba certificate, the price of the gem will be significantly higher. This is due to the fact that two Brazilian fields are currently completely depleted. The first deposit in the state of Paraiba – a hill about 65 meters high – was depleted to zero in just a few weeks. Two years after this, a new field was discovered – Rio Grande do Norte. It also produced specimens unique in their beauty and was soon exhausted.

Today, only two regions supply the market with gem-quality minerals. In 2001, Paraiba tourmalines were discovered in Africa – at the Eduku mine in Nigeria. Three years later, the Muyane field was discovered in Mozambique. Stones of Mozambican origin are rated higher because they have a brighter blue hue and a pronounced neon glow. The gem is so rare that it is mined using gentle methods and only by hand.

It is worth noting that it is worth paying extra for the origin only if this deposit is registered in an international certificate, and this certificate must be issued by a geological center or a geological institute of a high level of authority – for example:

  • Global Recycle Standard (GRS)
  • Gubelin Gem Lab
  • Gemological Institute of America (GIA)

We have prepared a video for you on how to choose a collectible Paraiba tourmaline, what criteria it must meet and how to check its quality.

This type of stone belongs to the second group of purity (Type II) and may allow internal inclusions. The hardness of Paraiba tourmaline on the Mohs scale is 7-7,5, which is closer to such gems as emerald, morganite, and aquamarine.

What affects the cost of a stone?

  1. Origin
  2. Color
  3. Cleanliness
  4. Cut quality
  5. Presence of traces of refining (for example, heat treatment)
  6. Complete set – purchase a set or a separate stone.

Another factor that affects the cost of this gem is the quality of the cut. A very important point is that even a stone that nature has endowed with both beautiful color and excellent purity can be conditionally “killed” by poor cutting quality. Precisely because there are quite a few stones of large magnification, the cutter always has a very serious temptation to increase the carat value, as they say, to cut a stone of a larger size. Because a cut that has excellent proportions, that has excellent symmetry, so that the pavilion is not displaced, so that the relative position of the face is such that the stone burns and plays – with such an excellent cut, as a rule, there is a very large loss of useful material. Accordingly, with a good cut, we get a stone of a lower carat value, and in this case, the cost per 1 carat will be higher with this level of processing.

Also, in addition to all of the above, the final cost can be affected by the purchase of not one stone, but a set of stones – when they are selected in the same color, in the same quality of cut with the same transparency, that is, the stones will be approximately the same level, and at the same time have an ideal shape – in such situation, the cost will most likely increase by 30 percent.

In general, we have considered all the factors that we should know about in order not to make a mistake in selecting such a stone. You can also add a few words about the deposits – today three regions of the world provide us with jewelry Paraiba tourmaline: in 2001, a deposit was discovered in Nigeria, three years later a deposit was discovered in Mozambique, and today the market is still filled mostly with stones with origin Mozambique.

High-carat Paraiba tourmalines, combining rich color and a high degree of purity, are often featured in the creations of the CHAMOVSKIKH jewelry house, giving the jewelry special sophistication and splendor.
