All About Garnets
I get a lot of questions from prospectors about garnets, their value and what they tell us about the geology of some types of mineral deposits. So I thought it would be a good idea to take a closer look at the lowly garnet and learn a bit more about it.
The Geology of Diamond Deposits
New theories have been developed and they may lead to new discoveries and give prospectors some new insight on where to look for diamonds.
