Distinguishing Features of The Gem Quality

With the different qualities of the stones available in the market, it may be difficult to differentiate a premium quality stone from an average one. However, there are several criteria that you can use to know that.

The first one is clarity, Andalusite often contains tiny needle-like features, but as long as they do not have pleochroism, they are good to go. The second factor is the Carat weight. Bigger gems cost more than smaller gems. This factor explains why the Brazilian gems are more expensive since they contain more carats.

The last factor is the cutting of the gem. Poorly cut gems are dull and fail to reflect color play, therefore having a lower value.


As much as we have a wide variety of gems in the market, you must be aware of gems manufactured in the laboratory. Therefore, you must get the exact cut details before purchasing an Andalusite gem. You must also be careful not to get duped by the lower prices of some gems in the market.
