Why the prices are big difference for k9 crystals from different factories?

 

You should notice that the prices are quite difference from different factories. And all factories told you that they quoted the prices with K9 crystal raw material.

 

But why the prices are such different? Is there any mistake or someone lie to you? NO!!!

 

The truth is that they did not tell you what grades of K9 crystal raw material they used and there are A,B,C,D,E grades for K9 crystals raw materials. 


The differences as belows.


A grade:

No inner impurities and bubbles inside

Without non-homogeneous inside

Perfect shape


B grade:

No inner impurities inside,but have few TINY bubbles inside

Without non-homogeneous inside

Perfect shape


C grade:

No inner impurities inside,but have some SMALL bubbles inside

Without non-homogeneous inside

Perfect shape


D and E grade(also called K7 crystals)

Have small inner impurities inside,but have many bubbles(big and small) inside

Without non-homogeneous inside

The shape is no good and the surface is not flat

 

Different grades,different quality,the prices are big difference.

 

Now you know why the prices are big difference from different factories with so called”K9 crystals”.


Please consider the above difference when you compare the prices and make you decision before placing your order.
