Some other indicators are also minerals for gold which are detectable by MDs that can lead to raw diamond deposits. The two common minerals which are good indicators of gold are the Garnet and Magnetite. Other minerals as good indicators of diamonds are the black picroilmenite, chromium garnets, glassy green olivine and magnetite.

If it happens that you found gold, there are good chances that the rocks nearby have diamond deposits. Other than diamonds, there could also be pure valuable crystals of garnet. These are precious gemstones that comes in different colors which can be shades of green, red, yellow and orange.

These type of equipments operate at a higher operating frequency as compared to the standard MDs. It's because theory states that, the higher frequency - the greater the sensitivity of the MD to detect small gold such as nuggets.
