I would agree, as I know one person who can't wear jewelry with certain
types of plating without getting a noticeable rash wherever it contacts
their skin. Pure gold does not produce the same effect, although gold
platings less than 24K do, as well as silver plating.
It sure makes gift-buying expensive:)

Hi Dave,
Nickel itch is one of prospective disorders of record found among
those in
the plating industry.
I have members of my extended family who have been diagnosed with such
sensitivity.
It is not, in this case "urban legend" I can attest.
Very best,
Joe
Health effects of nickel
Nickel is a compound that occurs in the environment only at very low
levels.
Humans use nickel for many different applications. The most common
application of nickel is the use as an ingredient of steal and other
metal products. It
can be found in common metal products such as jewellery.
Humans may be exposed to nickel by breathing air, _drinking water_
(http://www.lenntech.com/drinking-water-FAQ.htm) , eating food or
smoking cigarettes.
Skin contact with nickel-contaminated soil or water may also result in
nickel
exposure. In small quantities nickel is essential, but when the uptake
is too
high it can be a danger to human health.
An uptake of too large quantities of nickel has the following
consequences:
- Higher chances of development of lung cancer, nose cancer, larynx
cancer
and prostate cancer
- Sickness and dizziness after exposure to nickel gas
- Lung embolism
- Respiratory failure
- Birth defects
- Asthma and chronic bronchitis
- Allergic reactions such as skin rashes, mainly from jewellery
- Heart disorders
Nickel fumes are respiratory irritants and may cause pneumonitis.
Exposure
to nickel and its compounds may result in the development of a
dermatitis
known as "nickel itch" in sensitized individuals. The first symptom is
usually
itching, which occurs up to 7 days before skin eruption occurs. The
primary
skin eruption is erythematous, or follicular, which may be followed by
skin
ulceration. Nickel sensitivity, once acquired, appears to persist
indefinitely.
Carcinogenicity- Nickel and certain nickel compounds have been listed
by the
National Toxicology Program (NTP) as being reasonably anticipated to
be
carcinogens. The International Agency for Research on Cancer (IARC) has
listed
nickel compounds within group 1 (there is sufficient evidence for
carcinogenicity in humans) and nickel within group 2B (agents which
are possibly
carcinogenic to humans). OSHA does not regulate nickel as a carcinogen.
Nickel is
on the ACGIH Notice of Intended Changes as a Category A1, confirmed
human
carcinogen.
