Does Lianyungang produce crystals? Is there any simple way to tell the truth from the false?
Lianyungang is the crystal producing area, and Lianyungang Donghai is the famous crystal capital of China.
The method of distinguishing truth from falsehood by crystal:
1, look at the inclusion
Crystals are produced in nature. Due to environmental reasons, growing crystals usually contain cotton wool, cracks or other mineral inclusions. So generally speaking, when you get a gem, use the magnifying glass of 10X to see if there are any natural mineral inclusions or negative crystals. The common inclusions in crystals are cotton wadding or needle-shaped. As long as you see these things in it, it must be crystal stone.
2. Look at the appearance characteristics
For the original crystal stone, we can observe the luster, fracture and surface decoration of the gem. The crystal is glassy and conchoidal fracture, and the fracture surface is oily. The original crystal stone is a hexagonal prism with horizontal stripes or polygonal etching on the cylinder. If these characteristics are consistent, it means that this gem is crystal, otherwise it is ground rough stone or other gems.
3. Look at this color
Colors in crystal stones are generally unevenly distributed, often accompanied by ribbons. The synthesized crystal is formed under relatively stable conditions, and its color is uniform and bright. The natural colorless crystal has a smoky blue tone and a soft touch. The synthetic colorless crystal is white, dry and lifeless.
