Not much. Yellow in northern Laos is the closest material found in the market to Huangshi in Shoushantian. The output of Laoshan materials is relatively large, and the northern materials are not very noble collections. Tian Huangshi was deeply loved by emperors, and yellow became a symbol of nobility. In northern Laos, yellow is crystal clear, yellow and white blend, and some are shredded radish, which is very touching. The price is only half that of Shoushan Tianhuang. For collectors who like Tian Huangshi but don't have much money, yellow in northern Laos is a very good collection substitute. The formation conditions and composition of Laos stone are very similar to Shoushan stone, and the aesthetic degree is not lower than Shoushan stone. It can be said that "Laos stone" is the Shoushan stone in Laos. Laos stone and Shoushan stone are still slightly different. Laos stone is not as "oily" as Shoushan stone, so it needs careful observation and understanding. The reason why the price of Laos stone is lower than Shoushan stone is because it is not as famous as Shoushan stone, and Shoushan stone resources are basically exhausted. In this case, the old stone has become a substitute. However, the reserve of Laos stone is not very large, and it is estimated that it will be exhausted in the next few years. Therefore, the price of Laos stone has also risen rapidly, and there is also a lot of room for appreciation, which is very collectible.
