Target ID numbers of 35 platinum rings

On the internet, I had read that most platinum rings give you a real low target ID numbers. So I
decided to gather up the platinum rings that I still have and see what the numbers are while doing an air test. While 33 rings are Asian made.There are 2 rings made for the American market. I put a "$" after the target ID number to identify these 2 rings. I was surprised to see that so many platinum rings read so low. Many are down in the tin foil range. All the platinum rings are wedding bands except for one. It as very small and only was 0.8 grams in weight. This ring and 2 others, I could not determine what percentage of pure platinum they are. The weight is in grams ranged from 0.8 grams to 11.4 grams. Ring sizes ranged from 3.5 to 11. I provided this information on the different rings to help give you an idea what I tested. I used the new White's MXT with the 10 inch DD coil to give the target ID reading while in the coin and jewelry mode. On my White
 
Will let my friends know about your study, this is something I discovered long ago as my wifes wedding bands are platinum and was checking them years ago with my first Target ID unit, a Tek MK1 and I almost choked when I discovered what the parameters were. I have found 2 small Pt rings since that time but I dont really hunt where I might find things like that. Did find a gold earring with a small stone in it in a Dredge tailing pile years ago, have wondered about that one...Thanx again...HH...Geo
 
Great posting Terry.
Only problem is that I have never found a platinum ring. Looks like South Africans prefer gold!
Thanks again for a very informative posting.
 
A great post,Terry,and it looks like about the best way to even hope to find a plat is to dig every target.Unfortunately, I don't have any similar rings to sample with my detectors,which are different brands than yours.However,I would suspect the reading would still be 2-4.
 
Very interesting! But what do you mean as platinum? Really metal platinum or white gold?
On you tablet we can see how much the % of the alloy influences the electric answer of the item.
The pure metal, or the almost-pure metal, has a very high number. When the percentage increases the signal number drops quickly near to zero.
 
All rings in this report are made using platinum metal. There are no white gold rings in this report. The column called platinum numbers shows the percentage of pure platinum in that ring. 900 means that the ring is 90% pure platinum. 1000 means that the ring is 100% pure platinum metal. The reason that I find so many platinum rings here in Hawaii. Is that the Japanese people wear platinum wedding bands and they loose a lot of their rings here. One of the local ladies that metal detects here. She has found over 100 platinum rings in the last 6 years.

Hi Terry,
Got a question. Is there anything different about the width or thickness of the 900 3.6 gm ring (VDI #16) compared to the others? Is it a comfort fit by chance? Also the ring with a VDI of 12 looks a little out of place VDI wise, is it similar in shape to the 16?
Thanks, Tom
 
Hi Tom,
The ring that ID is 16 is comfort fit. It is a plain looking wedding band. One thing unusual is the way the date is inscribed in side. Most rings are like this 2002.9.21. The #16 ring has S65.6.8 for the date. I have only seem a couple rings that has the letter "S" used in showing the date and I have no idea what it means? The #12 ring is unusual in that it is a very thin band in thickness. I have read that they used different other materials to reduce the percentage of pure platinum in the rings. I have no way of knowing what is used in these rings.

Thanks Terry,
That kind of goes with what I have found with gold rings. The more rounded the cross section the higher the ID, likewise the thin, wide rings also tend to be a little higher. HH, Tom
 
I newer found a platinum ring. Even at the jewelry shop it is difficult here ( Italy) to find it. Usually it is used the yellow gold at 750
or the white gold if there is also a diamond on it. When there are coloured gems it is still used the yellow gold.
 
Hi Terry,
Ever found any of these? I see them advertised in the US. Conductivity of Titanium is about a third that of platinum.

Hi Eric,
Not that I know of. However I have found a couple rings that I have no idea what they are made of. My gold tester said that they are platinum but they are to light to be platinum. I had a friend that deals in buying and selling jewelry test them to. He told me that he had no idea either what material they are made of.
