zircon
Wuzhou wholesale
zircon, provides high quality zircon, in ***4 the latest style
zircon, long-term wholesale, with improvements in technology and
machine update, now we process comparable to zircon diamonds,
used in a variety of industries.The basic characteristics of
zircon
(1) mineral name; name of the mineral zircon.
　　(2) color: the common color of Zircon is colorless, blue,
yellow, green, Brown, red, purple
　　(3)-hardness: **7.5.
　　(4) the relative density: 3.*0 4.*3.
　　(5), luster shiny glass to adamantine luster.
　　(6) the refractive index: 1.***2.*1.
　　(7) birefringence slaughter: 0.****0.**9.
　　(8) color: weak.
　　(9) absorption: absorption of up to ***0, **3nm for the characteristic absorption
lines.
　　(*0) the Magnificat: a common mineral
inclusions, ghosting is obvious.Brittle,
edges and corners are easy to wear.
　　Zircon crystals can be divided into high,
medium and low levels of three cultivars.Refractive index, density, hardness values from low to high
is getting bigger.Type high birefringence
of zircon, zircon almost unrivaled refractive index.
Evaluation of zircon
　　Colorless and is one of the most popular
color of zircon can be natural, can also be formed by the heat
from yellow, Brown, red.For the fake
diamonds requires pure, transparent, displayed in ideal cut and
can fire bright color is a plus.The more
massive, more value Jane.
　　Blue zircon is the most valuable of all the
zircon, is also one of the most popular colors.Requires bright pure color, transparent, clean, cut to
perfection.The more massive, more
valuable.
　　Cut zircon, requirements to the stone counter top vertical
axis, so that when people look after you don't see ghosting and
multicolor faceted.

Identification of zircon
　　And similar zircon gem diamonds,
aquamarines, emeralds, gold, Sapphire, spinel, synthetic cubic
zirconia, synthetic rutile, glass, etc.High refractive index, high gloss, high birefringence, a
large number of spectral absorption lines, absorption lines are
characterized by **3nm the main distinguishing characteristics of
zircon.
The origin of a diamond
　　Thailand, Sri Lanka as a major producer of
zircon.Sri Lanka is famous for Zircons
from a variety of colors, and Thailand as the main source of
gem-quality zircon.Other producers include
Myanmar, France, and Australia, Tanzania, etc.
　　China also produced gem-quality
zircon.Penglai, Hainan Province red zircon
production.Giant crystals of Zircons from
mingxi, Fujian produced colorless or white.
Quality assessment for zircon
　　Zircon belongs to the low block stones, but
the difference in quality between the high and low price as
well.According to the current market
standards, its assessment based primarily on the following
several points.
　　(1) color: the amount of one of the most
popular color of Zircons from two, clear and blue, where the blue
zircon prices higher.Transparent colorless
zircon only and a diamond, with no shades of gray or Brown has
the effect of blinking lights and a diamond.
　　(2) the clarity: clarity of zircon in *0 times
magnification observation values, should not have any obvious
flaws, and if there is any visible blemishes, inclusions, cracks
of zircon, its value will be greatly reduced.
　　(3) cutting ratio and orientation, Zircon
seemed pretty, the main factor is due to its high refractive
index and high dispersion, followed by cutting, polishing and
other.Thailand
cut craftsman seems to know this, they continued to cut the
proportion of standardized, thus win the
market.Ignore zircon clarity, simply the
pursuit of weight, was not desirable.
　　Due to the high refractive index of high
zircon, parallel or near parallel to the countertop, then gem
will displayed by the birefringence caused by ambiguity on the
back, bigger stones this phenomenon more
clearly.To avoid this, gem cutting
perpendicular to the optical axis should be on the
table.
