“IMPERIAL GREEN” 
THE STONE OF IMMORTALTY, THE COLOR OF ENVY

On the contrary to common perception, the color of jadeite actually covers the whole color spectrum, from red to violet with different levels of intensities and brightness. Even the most well-known green comes in a wide range of hues and saturations. Color itself is also the most important quality factor for a piece of jadeite's value, with the other two factors being texture and transparency. 

We are honored in this auction to offer LOT 2138, a set of necklace and earrings with twelve smoothly carved and perfectly matched jadeite cabochons. It showcases the absolute finest-quality of jadeites - almost transparent with a vibrant and vivid green color. The combination of these qualities is known as “Imperial Jade”, as opinions from both prestigious gemological laboratories SSEF and Gübelin confirm in their reports. The color is pure and penetrating, a vivid hue with no hint of gray that looks bright and intensive even from a distance. The texture of the best jadeite so fine that it appears semitransparent – the text you can read through it would be slightly blurred. It is created by tight interlocking crystals and an absence of any impurities such as veins and cloudiness. With light entering and penetrating below the surface of the stone, semitransparent jadeite like this display an alluring brilliance. It almost appears to glow, intensifying the charm of the lush green color even further.

Thousands of years ago, the mountain rocks containing jadeite-gem was carried by water from the mountain tops to the rivers. Eventually they washed and weathered to contain only the better and finer quality mineral. Jadeite’s interlocking crystals, also called grains, produce a tightly inter-grown, compact mass that bonds together. This selection of jadeite rough by nature has left us with what is known as a standard for "old mine" material. The gem-grade jadeite deposit in Burma, now Myanmar, is only formed under extremely rare conditions involving specific temperature and pressure, together with the right mix of elements in the surrounding rocks. With the development of modern mining technology, the non-renewable jadeite deposit had been mined at a drastic rate. To delay the process of depletion, the Myanmar authority has been implementing controls over the volume of jadeite production and export, which also contributes to the ever-increasing jadeite value in the long-run. It was believed that the gem possessed many virtues such as healing powers, good luck, prosperity, longevity, happiness and love.
