Many people think that glass jadeite must be more expensive than ice jadeite. Is this the case? This statement is not comprehensive. For example: the price of a small flower in a glass type, the price of a ring face is generally between several thousand yuan and several tens of thousands of yuan; and the large, ice-shaped jade flower pieces full of green and full shape can be valuable. Millions of dollars.
In which case is it important to distinguish between ice and glass? For white glass and ice jade, it is very important to determine whether it is ice or glass. Because the same size of white glass species and ice jadeite are about 10 times different in price. Many people often buy white ice flower pieces as glass, thinking that they only use a few thousand dollars to buy glass flower pieces that others have to spend tens of thousands of dollars to buy. In fact, the white ice flower pieces he bought are It is worth a few thousand dollars and it is not cheap to buy.
