A
Green Finger
A few of us are "Blessed" with "Green Finger" phenomena.
Green Finger phenomena is nothing more than the copper within the ring
reacting with the body chemistry of a minority of the wearers.
This can even be affected by diet!
Green Finger is not dangerous and should not be a reason
to panic.
It is actually a sign you own a precious metal (and you
have special body chemistry).
Generally, this reaction fades away and is not evident
after a few weeks of wear as the superficial copper, that copper which
is in contact with the skin of the finger, completes its reaction.
Removing
Discoloration
There is good news.
As long at the sterling piece has not been exposed to the point of
pitting, a good silver polish will clean most discoloration.
If your silver does
discolor, your best choice for polishing and cleaning will depend
on the components in your particular piece of jewelry. If your jewelry
includes gemstones or glass beads, it may be best to use a gentle,
specialized jewelry cleaning solution. Many of these come with little
dunk-tanks, which allow you to soak your jewelry for a period of time.
Before using any cleaner, make sure that all of the
components in your jewelry piece can withstand such cleaning. For
example, softer, more porous gemstones (such as some types of turquoise)
and other natural materials (such as coral) may be damaged by submersion
or application of chemicals. Before using a cleaner, ask your jewelry
cleaner supplier specifically whether their products may harm these
materials.
Sterling silver will shine by rubbing or buffing it with
a soft cotton cloth or treated polishing cloth following cleaning.
Preventing
Discoloration
Wearing your silver jewelry often will actually decrease
its propensity for tarnishing as the superficial reactive copper is
exposed over time.
Some owners elect to have rhodium plating for their
pieces. Local jewelers will often provide this service. Rhodium
plating with help prevent discoloration, however the plating tends to
wear off in time and the discoloration may return.
When you are not wearing your jewelry, the best way to protect it from
tarnish is to wrap it in special anti-tarnish paper, and tuck it away
safely in your jewelry box, away from sun and moisture. If you store
silver in sealed plastic bags, it will be less prone to tarnish. Jewelry
containing pearls, should not be stored in plastic bags.
