The more the facets are cut, the more transparent the gems, and the purer the interior, the more the fire will flash. Therefore, we must pay attention to the purchase: the ratio of cutting is better, the symmetry and polishing are better, and the fire is definitely stronger.

General Rule 2: I don’t look at the contents, it’s not clear enough.

The purer it is, the more expensive it is. The fire is not strong, and it is also related to the inclusions. The less, the purer and more transparent the inclusions, the higher the value.

Among all kinds of cockroaches, cracks are the most taboo. Gems are rapidly cooled at the heat treatment temperature, or cracks or corners are generated during the grinding vibration and collision, which will reduce the value of the stone.

General Rule 4: Not superstitious, can not be fooled

The same country also has different mining areas, and the price is also very different. In addition, most of the gemstones are produced by the store, and the average consumer knows the place of origin. It can be used as a reference when purchasing, but it is not necessary to be around. The main reason is to look at the color of the gem itself. To see more and compare it, you can enhance your appreciation. ability.
