I received a very nice Solstice gift recently, a beautiful Asian-made
bracelet, about 2" wide, that appeared to have copper and some other metals
woven into it. I proceeded to wear it for about a week, before noticing a gray
substance rubbing off and staining the skin around my wrist. This didn't happen
at first, but got worse, especially when I would sweat a little while wearing
it. It made me a little nervous, because it was starting to stain my skin gray,
for a day or so after taking it off.
So I decided to call the 800 number of the company that sells it, and
ask exactly what the metal is, on the off chance that it might be something
toxic, like lead. When this person bought me the gift, she was under the
impression it was silver ( I haven't looked at their catalog myself, so I
don't know how it was presented ), but I've worn silver rings for many years
and they certainly don't do this, or even oxidize much from my skin.
When I called, it was difficult to get the woman there to even answer
my question. She beat around the bush, telling me that the bracelet is supposed
to help the body by sending copper into the bloodstream, etc. The same
"electromagnetic...electrical life currents..." silly new-age-sounding hype (
IMO ) as the little sheet that comes with the bracelet. But I pointed out that
the only part of the bracelet that contacts my skin, is not the copper part on
top, but the silvery part around my wrist, and this is what's rubbing off into
my skin. I'm not interested in legend, superstition or snake oil here, I'm
interested in science. I'm a rocket scientist.
After beating around the bush some more, she told me the bracelets are
made "from whatever metal is available at the time". I asked if it could be
made from lead then? She said absolutely not. Then she said; "let me see ( as
if she was actually readng something, which I doubted ) ...this shipment says
it's made of nickel". Bingo! So, not being familiar with the actual scientific
effects of nickel on the body, I did a quick search on "nickel" on the web,
using Alta Vista's search engine and at amazon.com ( the world's largest book
dealer ) , I found:

Eczematous sensitivity to nickel is now the most common cause of allergic
contact dermatitis throughout the industrialized world. Most contact is
through costume jewelry, buttons, zip fasteners, earrings; occupationally
provoked cases are few because of improved occupational hygiene, but early
exposure via jewelry, etc. can predispose individuals for later industrial
dermatitis. Topics treated here include: chemistry, analysis, and monitoring;
human exposure and chemobiokinetics; carcinogenicity; alloys and coatings;
epidemiology; drug interactions; orthopedic prostheses; dental treatment;
social and demographic aspects. Acidic paper. Annotation copyright Book News,

Evaluates close to 900 studies in an effort to determine the role of various
nickel compounds as environmental hazards and causes of human diseases,
including cancer. A special effort is made to determine the specific exposure
levels for nickel and nickel compounds that pose a threat to the environment,
the general public, and workers exposed to nickel-containing dusts and fumes.
A section on sources of exposure evaluates both natural and man-made releases
into the environment, offering especially detailed information on emissions
associated with the nickel industry, the combustion of fossil fuels, and the
incineration of sewage sludge and waste. Exposure of the general population is
noted to occur via inhaled air, ingestion of food and drinking-water, and
dermal contact, particularly with jewelry and coins.
Because most health hazards associated with occupational exposure have resulted
from inhalation, a section devoted to kinetics and metabolism concentrates on
mechanisms of deposition, retention, and clearance of nickel from the human
respiratory tract. The most extensive section reviews the large body of data
from experimental studies of the effects of short- and long-term exposures on
the respiratory tract, endocrine system, cardiovascular system, immune system,
skin and eye. Tests for mutagenicity, embryotoxicity, teratogenicity, and
carcinogenicity are also critically reviewed, with particular attention given
to possible mechanisms of nickel carcinogenicity. The final section assesses
effects on the human respiratory system, kidney, cardiovascular system, skin
and eye. Evaluation of the potential for carcinogenicity draws upon increased
rates of nasal and lung cancer reported in several epidemiological studies of
exposed workers. These studies provide evidence that inhalation of nickel dust
and some soluble and insoluble nickel salts carries a risk of carcinogenicity."
Can someone with credentials please enlighten me about the
possibilities of whether this grayish staining of my skin might be something
that can get into my bloodstream and cause me serious harm? I really like the
bracelet but obviously won't wear it if I have to risk cancer or toxicity from
And I imagine the company that sells them would like to know. I've
already suggested that they be more careful in the future, about the metals
involved. Jeez, I'd think for the price paid for this ( about $50 I'd think )
they could have used real silver, which is only about $5 an ounce, right?
Combined with low cost Asian labor, why not?
Is there anyone out there with metals toxicology/jewelry experience
that can speak authoritatively on this?
