Colour is the most important factors in determining the value of each piece of Jadeite Jade. The purity of the colour is measured by the brilliance, hue, intensity, saturation and evenness of the Jadeitec Jade. A good piece of Jadeite Jade has a single shade of colour, or with its colour evenly distributed.
Clarity is the visual appearance of internal characteristics of the Jadeite. They are inclusions that are crystals of foreign material or structural imperfections that can appear whitish, cloudy or even blackish, which greatly influence the transparency of the Jadeite Jade.
Cutting relates to the style and craftsmanship on the Jadeite. The imperfection of the crystal formations in the Jadeite determine the “art and craft” to be carried out and the degree of expertise to craft the raw material to its fullest potential.
Crack relates to the random, non-directional fracture inside the jadeite jade during its formation under the earth. They are visible to the naked eye. It will take some effort to recognize cracks and natural veins.
Textures relates to the internal structure of the jadeite, which is made up of multi-crystalline interlocking grains. The larger crystals result in coarse grain texture, which sometime mistaken as hairline crack. The highest quality of Jadeite has very fine crystals grain aggregate, which contribute to very fine texture that results in highly translucency or transparent.
Transparency is the degree to which light can penetrate through the Jadeite. The Chinese call this the ‘water content’ of the Jadeite Jade. This is due to the fineness of granular structure that caused the Jadeite to look transparent. It will be very rare and pricey to chance upon any “Glassy” Jadeite jade. I
Volume relates to the size of the jade before & after craftsmanship. The size does play a part in the pricing of Jadeite.
