So what about that Jade?
I’ve been asked a number of times regarding Jade items if these jade
items are real jade.
There are a number of places to review jade descriptions
and definitions on the internet.
Do a Google Search on Jade Grades.
But Reader Beware:
When an internet Site shares that it is now acceptable to
have enhanced Jade Grade B and or
C Grades there is a likely chance that the
company is selling enhanced Jade.
Enhanced jade is showing up in the market.
A friend whose family is in the Jade Brokerage Business
of Mined Jade pieces shared, that if the Jade piece
looks too good the piece needs to be scrutinized by the buyer.
We’re finding out even half decent jade pieces need to
looked at more carefully.
It’s no longer just the “High Grade”
So Called Imperial Pieces that are enhanced;
it’s also what we would consider everyday pieces.
So here’s a brief summary of terms commonly used when
jade is described.
The Jadeite showing up on market presently can be classified into
A Grade Jade, B Grade Jade ,C Grade Jade and B+C Grade Enhanced Jade.
A Grade Jade:
Natural jadeite without undergoing any artificial treatment,
alteration or enhancement.
B Grade Jade: jadeite has undergone an acid treatment,
removal of impurities, impregnated with colloidal silica or resin.
This kind of jadeite will yellow
gradually in 3-5 years of time and then the surface color will
wear off due to the age of the resin or colloid.
The jadeite has been destroyed during the acid treatment which
affects its durability.
C Grade Jade: jadeite has undergone artificial treatment,
plus adding the
new pigment substance.
Not only has its internal texture has been undermined
but also its internal color was artificially added in.
B+C Grade Jade- Jade that has been impregnated with
colloidal silica or resin as well as dyed with a pigment.
Jadeite is: (Description found in the internet)
A pyroxene mineral consisting of silicate of sodium
and aluminum, occurring in the form of light green
It is the tougher and more highly prized variety of jade.
（Jadeite and nephrite are known to the Chinese as Jade).
A hard, translucent variety of jade which is rarer than
the other varieties of nephrite and comes in a variety of colors
such as orange, pink,
yellow, brown, blue, violet, and black.
