Well, "REVIER" I think Ron has been detecting sense 1978 give or take a couple of years that he just left out all the information about,
Size,
Shape,
Connected loop (closed solid loop)
Open loop (semicircle)
Alloy Content,
Positioning in the ground,(flat, edged, tilted) could actually change the detectors response to that object. But, I'm pretty sure he knows about the differences.
At this point lets rewind just a bit!
In the Ron's title post he states
Ron's said:
It was a large earring and was kind of heavyy
And to that you replied,
REVIER said:
but I have found several silver earrings that because due to the small size
So I just assumed that you missed Ron's reference to "LARGE" and "HEAVY"
So I posted this,

I took him to say it was pretty large and pretty heavy
Ron, has probably figured in a solid loop vs an open loop, thickness, weight, total mass and seeing how he was referring to using the detector as bit of a possible silver test for the object in question and would have been laying FLAT (placed) on the Ground (he already found it). So, based on that I'm thinking that if its pretty solid, a solid loop or maybe not a loop at all, and its silver then it should hit a little higher in response then the normal costume jewelry. If its total mass is at lest that of a dime or more then the detector response might be close to that of a dime (laying flat on top of the ground, not in different variables under the ground)
First test I would do not having an actual silver test kit, is
If its heavy I would see if it sticks to a magnet, if it don't then that rules out a lot of CHEAP core alloys.
Then in the weight department it couldn't be aluminium unless its HUGE its will just feel to light for its size.
Next test for silver is to nick one edge and see if its plated,
Next is a simple bleach test, sterling silver oxidizes almost immediately when you put a drop of bleach on it. So, you can polish an area until its shinny then place a drop of bleach on and see it turns dark.
None of the above is PROOF of the object being silver buts if it passes the test then its worth either saving it as a piece of silver or maybe having it tested.
