Tested different ring sizes--ALL of them gold plated-- marked with GE gold electroplate--tested with Fisher F5 passing each ring at least 6 times under the coil for a consistant number.
Items in the ground may read lower or higher on the screen, depending on soil conditions and how long item has been buried.
The rings that VDI'd above 50 are thicker than the smaller thin sizes rings.The rings reading above VDI 60 are big mens rings--close to a class ring size.
VDI number then the karat plating and then the ring size.
THESE ARE ALL PLATED RINGS !!!!!!!
In which the base metal is unknown. NON plated gold rings will VDI differently, possibly lower due to gold being a lower conductor.
