Zircon is a kind of natural mineral, it is itself a block in gems. Colorless transparent zircon through careful ponder, the good substitute is diamond. The refractive index to zircon with diamonds, dispersion also 2 near. So look from exterior, zircon will also flashing color light, and pandora bracelets charms diamond very much alike.
Diamond has a strong birefringence that it has two refractive index, and the difference between two refractive index is bigger. This leads to a very special optical phenomenon, when use a magnifying glass observation ponder good zircon finished product, by its end face can see bottom pandoras surface and LengXian have obvious double. Diamond because is "all plasmids," never have double phenomenon, this could be the difference between zircon, and the true diamond.
In addition, the proportion of zircon for the proportion of 4.69 and diamond opioids, namely pandora zircon is only the 1.33 times diamonds. However, only with the proportion of inconvenience observation after instrumental determination to know.
White pandora braelet tungsten
This is a kind of common nature for minerals, composition of tungsten acid calcium (CaWO4). It is characteristic of the hardness is low, only for MaShi hardness 5, can be ordinary glass and knives scratch. It is very big, the proportion of 6.1, is diamond 1.74 times, parcel.meet quite pandora necklace discount heavy.
Colorless transparent white tungsten gem raw material, as it wondering, the beauty of the color flash can almost comparable with diamonds. But, white tungsten mine, consider good hardness too low because if often wear, gems can be scratch sueding dust lose beautiful luster. Therefore, it pandora chain usually just a gem collectors treasure is tasted, not as an appreciation of the inlaid jewellery with.
Artificial rutile
Rutile is a very common natural mineral, its composition is TiO2, hardness six - 6.5, a proportion pandora jewelry store of 4.2-4.4, refractive index is even higher, than diamond of 2.90 2.60 -. Rutile because, so refractive indexes into gems high thinking appears bright, shining after the flash, dispersion and extremely strong, make flash as a rainbow of colors change, appear very beautiful. Unfortunately natural rutile were pandora rings jewellery almost all opaque or, at best, in crystal edge, so some pervious to light natural rutile gem is rare, and particles are small.
Due to the excellent used as gems are rutile properties, so people have been studying scientific methods of synthesis of it. In 1947, the United States lead industry company firstly with flame out pandora jewelry review man-made rutile melt legal system. One of the colorless transparent, who is mainly used as diamond substitute or fake products. With colourless transparent artificial rutile meditate into gems shining, colorful, more than a real diamond, often called "colorful drill" or "colorless diamond".Artificial jewellerys rutile ponder the finished product after, the so-called "colorful, and a real diamond drill" easy distinction. Because the birefringence have strong rutile, use a magnifying glass from top surface observation "colorful, can discover auger" at the bottom of the LengXian's remarkable double, true diamond is never appear double. In addition, "colorful diamond" because flash too gorgeous, with no clear milky white light, it seems that a vulgar feeling.
