Trade Name Index
As mentioned in our previous post about trade names, trade names are designed to make a material more marketable and do not often truly represent what the mineral actually is. It can be hard to keep up with the sheer number of trade names these days, but we are here to help! We have researched every trade name we could find currently that is either confusing, known to be fraudulent, or just inaccurately describe the mineral it claims to be.
Here is a list of some of the resources we used in the compilation of this index (please check them out!):
Crystal Trade Names, Synonyms and Misomers by Solstice Stones

DISCLAIMER
Some of these trade names were also supplied by fellow members of the minerals industry, and may not be present in the sources listed. Some of these trade names also come from my own experience in this industry both as a geologist and as a seller. There is always going to be more trade names created, and more we haven't come across yet, so this list will be updated on a monthly basis. If you have a trade name please submit it to us at waikatocrystals@gmail.com and we will research it and add it to this index!
