Water gallbladder agate products favored

In an auction recently held, a Qing agate made a price of 7,000 yuan. Although this is not a high price, it can cause ordinary collectors to attach great importance to water agate products.

Agate is one of the most precious varieties of agate. It is characterized by a closed hollow in the agate and contains water. There is a sound of water when shaking, and you can see how the water flows in the agate, which has a very high investment and collection value. It is even harder to show the “water” to the right extent in the case of a hardness of 7 to sculpt the water agate into a handicraft. So water agate is particularly precious in jade.

In the auction market in 2007, there was once a Qinglong Longgang Agate Shuangzhi Paper Town, which was valued at 30,000 to 60,000 yuan and the transaction price was 78,400 yuan (as shown in the figure).

Instrument type and the end of the "Daoguang system" rules and neat. This device appears to be graceful, but it is an ideal collection for the tea ceremony.

Jade carving craftsmen in the selection of agate stone, we must first determine that it has "water", and then use a cutting machine to cut the agate, but also when cutting right, cut away from the water and gallbladder, can not see the water; cut Too close, it is easy to cut the "bile" and the agate that breaks the "bile" loses the value of carving. To be just right, not far, you can see the water, and you know the location and size of the gall. This is undoubtedly an important reason why water agate and agate products are sought after. However, this has also led to an endless stream of market frauds.

After the initial carving, the water gallblades agate's main falsification means is to cut or pry open one of the easily-perceived parts, fill the hole with water in the middle, then glue it with strong glue, and repair, polish and polish it. Real water agate. Some dry agate dry water, counterfeiters hole and then block water after the plug, block some of the cover to make people not aware.

In some cases, it is not clear even if dealers sell aquariums that are genuine or fake. For collectors, a tenfold magnifying glass should be used to carefully observe the agate agate product. If there is any doubt, use a knife or a needle to scratch it. Since the agate hardness is 7, the knife hardness is 5 to 5.5. If the fake part is glued, the hardness cannot reach 7, and it can be swiped with a knife. If conditions permit, experts can be asked to identify.
