For those of your who are experts in metallurgy-
We are trying to identify the metal makeup of two nearly identical
rings for a value document. The rings both contain a single pearl,
are fabricated pieces, and appear to be of Far East origin based
solely on the style of construction. They are both incredibly light
weight in design. Here’s what we know about the metal:
White in color
A small shaving taken from the inside of the shank does not
readily ball up with our oxygen/propane torch. A sharp, oxidizing
flame will get it to roll up.
When heated, the small shaving developed a blue oxide
A streak test on a stone with aqua regia applied showed it most
similar in reaction to stainless steel. We tested it against
stainless, platinum, and palladium.
There are some interesting details of how these rings are fabricated
that may or may not help with identification:
They are put together with silver solder
One of the ring shanks, which is very thin (1.8mm wide by.8mm
thick), is made of very thin strips of white metal layed side by
side and laminated together to form the shank. When I look at the
inside of the shank or the back of the shank, I can see the
striations running the length of the shank.
Thankfully, we don’t have to size either of them! However, we would
like to accurately describe the metal. We suspect it is some alloy
of stainless steel. Is there a definitive test for stainless steel?
Thanks in advance.
