White gold sound vs. yellow gold sound.... Big difference???

[RobRcer]

I was messing around air testing my Excalibur. I ran a 14K yellow ring by it, and it made a low, good, repeatable tone. Then i ran the 14K white ring, which is considerably heavier than the yellow, and it made a low tone, but it blipped, and cracked. Do any of yall know why? It sounds like i might pass over it thinking it was junk. From now on im gonna dig everything except for what i know is iron. The Excal can pick up good items next to iron, ive found many coins sitting right next to iron, but it makes a signal that sounds alot like junk.

P.S.
Some other hints i found air testing with Excalibur...
Gold rings are blocked out of the Excal around the 9 disc. area.
Sounds seem to vary slightly depending on where the Threshold is.

White gold, unless I'm mistaken, has some Nickel alloyed with it, along with some other metals. Nickel is a low-conductive metal, and this will lower the conductive signature of a set alloy of white gold, compared to the same alloy of yellow gold.

You're on the money as usual Beachcomber, silver and nickel are the alloys usually used. Some of the better white gold (18k +) is made with silver and palladium instead of nickel as it is hypoallergenic. Nickel causes a rash in many people especially with rings. This mix should read higher as palladium is akin to platinum.

Thanks....I never knew that some people are allergic to the nickel in White Gold.
