Some of the gemstone names we commonly use can be very confusing, and often costly to those unaware. For example, ‘Indian Jade’ is actually Aventurine, a form of quartz. The reference to ‘Jade’ is confusing and simply incorrect.
There are many such names that are still in use and you need to be careful when purchasing stones that use common names without referring to the true gemological name.
If you have purchased stones that were advertised using one of these names, the seller may have not know that the name is misleading. They also may have purchased it in good faith. However, often these names are used to confuse buyers and misrepresent stones.
Have a look at this list and you may find a few surprises.
