Jade, a beautiful and hard stone has been used and revered
in China since late Neolithic times.The pure white form is the
most highly valued,but it varies in translucency and colour to
include many nuances of Brown, Green, & Black.
Jade is visually unassuming, its tranquil colours imbued with
veins and crackles. Cool and smooth to the touch, it calms the
spirit and emits a musical note when struck.
To the Chinese Jade symbolizes nobility, beauty and purity. Its
physical properties become metaphors for the Confucian ideal
of the Junzi (noble and superior man)
Jade was endowed with magical and life giving powers. Daoist
alchemists in hoping to become immortal, ate an elixer of powdered
Jade. Jades were considered talismans against disease and evil spirits
The Shuowen Dictionary of the 2nd centuary AD, defines the characters
YU (jade) as thus:
Yu (Jade) is the fairest of stone and is endowed with five virtues
Clarity is its lustre, bright yet warm,
Rectitude is the translucency revealing the colour and markings
Wisdom is its pure and penetrating note when struck,
It is Courage,for it can be broken but does not bend.
Equity is its sharp edges which injure none.
Most of the world’s supply of fine Jadeite comes from Burma, yet deposits have been mined in other parts of the world. Stock listed here at Premium Gems was purchased outside of Burma from sources that bought pre-embargo.
Jadeite ranks as being 7 in hardness on the Moh’s scale and is known for its steel-like strength due to its fine crystalline structure within. It is a very tough gem, that resists chipping and breaking.
Nephrite ranks 6.5 on the Moh’s scale, being a somewhat coarser material, without the same fine polish Jadeite can achieve. Nephrite can have a ‘soapy’ appearance also that is very attractive. This gem is far more plentiful than Jadeite and was the traditional Jade used for the main part right up to and beyond the 18th century.
The methods of carving and polishing Jadeite have altered within the last one hundred years or so – with a preference now being given to the shinier, glassier finishes. The high luster that can be achieved with Jadeite is very beautiful and best shows the translucency within.
The colors of Nephrite Jade are not as bright – they are more muted, softer, and greyer (often mottled also).
Jadeite Jade can be classified into three categories: A, B & C.
A Grade Jadeite is natural jadeite that has not undergone any artificial treatment, alteration or enhancement. This kind of natural jadeite does not change with the passage of time. It can be preserved forever and wears well.
B Grade Jadeite: is defined as the natural jadeite having undergone a process of acid treatment, removed the impurities and impregnated with colloidal silica or resin. Normally, this kind of Jadeite will turn out yellow gradually in 5-10 years of time and then the surface color will come off due to the ageing of resin or colloid. Meanwhile, the composition of inherent texture of jadeite has been destroyed during the acid treatment, which affects immediately its durability.
C Grade Jadeite: is specified as the natural Jadeite having undergone artificial treatment, colloid impregnation plus adding a new pigment substance for coloring. We may also say that not only its internal texture is undermined but also its internal color is artificially introduced. Often aggregates of color that is too strong and blotchy gathered into the veins is an obvious indication of this process.
An absolutely spectacular piece with an amazing cut from this prestigious cutter. I am thrilled to own this, and can’t thank you enough.
