It usually depends on the type of jade you're trying to sell. Carved jade pieces are valued per piece, not by carats. Art and origin are the main factors of value. Although nephrite jade is the original skystone from China, fine jadeite, as shown here, is the most coveted jades in today's Chinese community.
The biggest auctions in the world focusing solely on latex are Myanmar Jade Auctions and China Jade Auctions. The most valuable type of jade is imperial jadeite jade, which has a bright green, semitransparent and evenly distributed coloration. From a mineralogical point of view, the value of jade also depends on the mineral composition, whether the jade is represented by nephrite or jadeite minerals. Later, after the looting by the British and French armies in 1860 of the Summer Palace in Beijing, where many Chinese jade objects were stolen and then headed to Europe, Damour re-analyzed the jade.
Culture and history have a significant influence on the jade market and on the perception of jade as a gemstone. However, today, colorless transparent jade called icy jade has become very popular among younger consumers. One of the first national sources of the stone were the White Jade (Yurungkash) and Black Jade (Karakash) rivers, near the city of Hetian (; a). That's why it's always good to consult with a jade expert to choose the highest quality jade with an appropriate budget.
Both are highly praised, but because of the better qualities of the mineral jadeite, jadeite jade is more valuable than nephrite jade.
