How is that

Be careful - You will get a gemstone with a window.

When a cut and polished gemstone has a window, gemstone won’t give the expected brilliance. It won’t reflect properly. Price will be low for gemstone which has a window. When you buy a cut and polish gem stone check for windows next time.
This happens due to bad cutting.

How to check.
See the gemstone directly without angling it. Put a paper with letters under the gem , if you can see the letters it has a window.

Be careful, gems are not giving the same color in all directions.

As a rough gem buyer , you need to understand the color direction of a gemstone that is called C AXIS .

specially in blue sapphires you need to see the correct color direction , becasue if you can not get the correct color direction to the facet, you cannot not get a good color gem stone.

Use a torch or a dicroscope to identify the correct color direction,
If you dont consider the correct color direction, you will end up with a big loss.
