vdi help needed on palladium

[ballpython]

i will be looking for a wedding ring that was lost from a car in the am and have a vdi question. the ring is a large gold and palladium. so my question is has any one found a palladium ring before and is so what did it vdi at? any help would be great thanks

This is a tough one. Palladium has a very low electrical conductivity, below that of pure nickel and even iron. By itself this would give it ferrous properties and would read well into the negative numbers on the VDI scale.

As an alloy, however, it is all dependent on how much gold is added into the mix.

As an educated guess I would expect it to be in the very low positive VDI numbers (0 to 9) or possibly in the high negative numbers (-10 to 0)

Just a guess.

Maybe this link will help: Periodic Table of Elements Sorted by Electrical Conductivity

thank you neil

Ring has been found. we ended up finding it by eye this area was cover with garbage. but a detector was ran over it after the find the rind was reading a vdi of +8 - +10 but was showing the ring to be very deep over 10 inch when we had it on top of the ground.

jbow its because of the low electrical conductivity made the detector think it was far away that's what i think it was.
