From themines to the counter, the beryl path is not easy...
A collection of multicolored beryls, even collected fromundeclared fragments of a mineral, is amazing. The natural beauty oftransparent crystals is fascinating. And although the cost of beryl is alwayssignificant, every gemstone lover tends to buy beryl. Because even a diamond,recognized as the "king" of jewelry, is in many ways inferior toberyl. Gem-quality beryls are rare. Known from antiquity, they aremined in a few deposits scattered around the world. With many difficulties,beryls are extracted from the darkness of the earth's interior, and sometimeswith incredible difficulties come to connoisseurs.Many of the stones are repurchased dozens of times, aredeposited in stone-cutting workshops for a long time, undergo serious changesin appearance (it happens - and filling), and only after long journeys throughthe secret world of human skill, hard work, ingenuity - and also inhumancruelty, greed and greed - become precious metals and freeze in the windows.
Physicaland chemical properties of beryl.·
Mineral class: silicates.·
The chemical formula is Be3Al2 (SiO3) 6.·
The shape of the crystals is a hexagonal prismaticcrystal.·
The cleft is imperfect.
Syngony: hexagonal.·
Transparency - from translucent to transparent.·
Glitter - glass.·
Mohs hardness is 7.5-8.·
Density - 2.75.·
Refraction or refraction period - 1.56-1.60.·
Fracture: conchoidal, uneven.·
Is the mineral brittle? Yes.Single crystals are able to reach several tens of kilogramsof mass. Often there are druses of crystals. The presence of impurities in thebody of the crystal determines its color. The high fracturing of the mineraleliminates the suitability of large monoliths of the mineral for use as ajewelry raw material.
Varieties ofnatural beryl
High-quality beryl pronounced color has their own names andare highly appreciated. Well known:
Emerald. The most expensive of the beryl, valued above thediamond for the purity of the green tone and the defect-free stone. The colorsof natural emeralds vary from mine to mine. The color range covers aconsiderable range of tones from yellow-green to blue-green. The most popularare the bright green stones of grassy shade. There is a great demand foremeralds, the color density of which reaches a dark green color.
High price and emeralds, the color of which varies within asingle crystal. Rhythmic zoning of the color density, as well as dichroism(color change when changing the angle of illumination of the crystal) areconsidered to be additional advantages of the stone.
Aquamarine. To a greater or lesser extent, repeats the colorof sea water or a backlit block of ice. The price is inferior to emerald due tothe relatively high level of mineral extraction. Most often it has a uniformcolor of varying intensity, but there are crystals with a heart of contrastinggolden hue and richly blue outer layers.
Small aquamarines have no great jewelry value. Stones of 3carats are in demand on the market. Large (more than 10 carats) inserts offaceted aquamarine are highly valued.
Heliodorus Light green beryl with a clear golden hue.Heliodor can be a completely transparent stone with a soft yellow tint. Theprice of gem-quality stones is about 20 dollars per carat. Mineral deposits areless common in the more common types of beryl.
In the past, with steady demand for blue aquamarines,heliodor was often subjected to thermal upgrading. Heating to 400 ° C destroysthe original golden color and gives the stone a blue tint.
The honey shade of the heliodor color indicates the highestquality of the gem. Such stones are rare and are always in high demand.
Morganite.Rare and expensive stone. The price of copies ofjewelry quality of the palest pink color starts from 25 dollars per carat.Increasing the red tonality in the color of morganite means an increase in thevalue of the stone. A defect-free jewelry insert from a red-burgundy morganiteof not too large size can be estimated at several hundred dollars.
In Europe and America, morganites enjoy the greatest demand,the tones of which coincide with the color of garden berries. Stones ofcrimson, cherry, strawberry, currant shade are traditionally popular on theshores of the Atlantic Ocean. In the East, valued pink morganite. In Russia,the gem may be called Vorobevit.
Goshenite, or colorless beryl, attracts the attention withthe restrained brilliance of a transparent stone. As a jewelry material,goshenite is valued less colored beryl. However, headsets decorated withgoshenite have considerable demand: unlike diamond, colorless beryl does notscatter multicolored highlights around it. Goshenite jewelery is strict andsolemn.
Gemologists note other varieties of beryl, less known to thegeneral public.
Augustit - blue beryl, can cost up to $ 150 per carat. Due tothe high price it is often fake. It tends to fade with time and under theinfluence of solar radiation.
Batstsit - blue beryl weak color intensity. A separate namewas awarded in honor of the discoverer, who determined the high content ofscandium in the mineral. In jewelry, it usually does not play a separate role,and is often used as ordinary beryl or aquamarine.
Bixbit - rarely found red beryl. One carat stone can cost upto 15 thousand rubles. Many enthusiastically call bixbit red emerald, but theprevalence of crimson beryl is much less than green beryl. It is mined in asingle field, periodically flooded by groundwater.
Mashish beryl- a stone of dense blue color, named after theBrazilian city near the gem deposit. Its properties are very similar toaugustite, although it fades noticeably faster. The instability of the colorwas the reason for the low price of the stone. Its production is consideredunprofitable and is extremely irregular.
Petskoit. Classification confusion is a phenomenon equallycharacteristic of all branches of scientific knowledge. Beautiful pink mineralpezzotait several years was considered a special kind of beryl. Found inMadagascar, he struck researchers with the brilliance of color and a fifteenpercent concentration of cesium in the composition of the stone.
The chemical formula of petszoitait allows to attribute it,like other crystallized aluminosilicates, to beryl, however, the structuralfeatures of the stone exclude a similar definition. In 2009, the mineralogistsfinally became convinced: a petszotaite crystal from any field - evenMadagascar, or even Afghan - is trigonal. While any mineral from the group ofberyl has hexagonal crystals.
Thus, Federico Pezzot, who found pink crystals in 2002,became the discoverer of a completely new mineral.
Rosterite- beryl, the color of which varies from fullcolorless to a pronounced pink color, and differs from other beryls by a highcontent of alkali metals among other impurities. In use and price is similar togoshenit.
