Description characteristic of the mineral.
Transparent Quartz (oxide of silicon) of yellow-lemon color. Can be got at the hours-long burning (baking) at a temperature near 500oC Amethyst (lilac and violet quartz, orange-yellow turns out, gold and yellow-brown citrine) or Smoky Quartz, tenderly-yellow turns out, gold citrine). Natural citrine usually light and often not (or zonally turbidized) quite clear with the areas of white or opaque quartz and cracks. A natural citrine is very poorly painted sometimes. Crystals with the natural colouring possess weak pleochroism.
Citrine, the goldish variety of quartz, due to the durability and rich colour palette, is widely used in jeweller wares and valued as jewels color stones. It Quartz (crystal oxide of silicon) of all of tints of yellow, goldish, orange and brown colors. Sun-bright and easy in treatment, it splendidly looks at oneself in the jeweller decorations of any style, especially sparkling and reflected from the polished surface of gold. Although more dark, the orange tint of citrine which is sometimes named madeira "Wine" (in color of the same name wine) is considered more preferable, majority chooses bright lemon tints, well combining with crayon tones all the same. Scratches glass. Sometimes a citrine is mixed up with topaz (he yet harder citrine) because colors of topaz and citrine can be alike, but topaz notedly harder and high-quality dearer than quartz. In the cut kind, colouring of citrine and topaz is identical.
Citriny the natural meet enough rarely. The mine deposits of citrines, related to miaroles pegmatites and mineral mine deposits, are known in Brazil (states of Baiya, Goyas, Minas-zherays), on Madagascar, in the USA (state Colorado), Spain (province Kordova), France and Great Britain (Scotland). In the CIS the magnificent crystals of citrines of wine-yellow color were found on Ural, found out beautiful citrines in Central Kazakhstan. Transparent, well painted stone are cut and used in such jeweller wares, as brooches, ear-rings, rings and coulombs. The separate large crystals of natural citrines are cut cabochon. The less attractive and semilucent unevenly painted crystals go to making of necklaces, bangles and other It is better not to acquire citrines of rare and dear tints from unfirmness of their colouring.
Greater part of entering sale of citrines is treated the high temperature of Amethysts, smoke-coloured Quartzs or morione (black quartz, in the pitchblende). The large transparent defect-free and evenly painted crystals of citrine or too dark (up to a brownish tint) crystals usually talk about the artificial origin of stone or annealing. By sight to define, a citrine is ennobled or not, has the natural or artificial colouring, it is practically impossible. Some citrines of rare tint lose colouring in course of time. The most important - not to purchase less dear citrines at price of topazs and other dear jewels.
Natural citrines is painted usually evenly enough. If at a citrine an apex is far darker than bottom base, such citrine is probably got the hours-long annealing of Amethyst (exactly Amethysts have the expressed unevenness of colouring along a crystal and save this property after annealing).
Cost of citrines in the world market presently relatively low from a presence practically undistinctive from natural synthetic and ennobled stone. Citriny today is actively synthesized from quartz raw material and have very high jeweller quality (cut synthetic citrines can excel the best natural or ennobled analogues). Price synthetic and ennobled natural citrines identical.
From considering of safety we do not recommend to acquire in private home collections the transparent defect-free (without visible internal defects) standards of citrines and other transparent defect-free stone measuring more than 1,5 х 1,5 х 1,5 sm - them can officially assimilate to jeweller raw material and licensed type of activity. If a standard is thin (without depending on the degree of zero-defects, thinner 1,5 sm) - without depending on an area and other sizes he is not raw material for jeweller industry in principle.
