Methods and risks:
Maintaining a clean diamond can sometimes be difficult,
as jewellery settings can obstruct cleaning efforts, and
oils, grease, and other hydrophobic materials adhere well
to a diamond's surface. Some jewelers provide their customers
with sudsy ammonia cleaning kits. Many jewelers use steam
cleaners. Some other jewelers sell small ultrasonic cleaners.
Home-based cleaning methods include immersing the diamond
in ammonia-based or ethyl alcohol-based solutions, or
even a solution of mild grease dissolving detergent and
warm water. Silver jewelery can be cleaned using aluminum
foil, baking soda, and hot water. However, this practice
is not recommended by most jewelers.
Certain types of cleaning can damage some jewellery.
For example, some class rings are coated with a dark pigment
to reduce their shininess. Some gemstones, such as white
topaz, have an overlay to produce certain colors. Ultrasonic
cleaning can remove this coating, if it is not a quality
piece. Ultrasonic cleaning is also contraindicated for
opals, pearls and amber, and any other gemstone that is
porous. Gemstones that are glued in (a common practice
with semiprecious stones in non-precious methods, and
in class rings) should not be placed into an ultrasonic
cleaner. An ultrasonic cleaner can cause stones that are
loose in their settings to come out. Jewellery should
always be examined for overlays and loose stones prior
to cleaning with an ultrasonic cleaner or a steam cleaner.
Jewelery Care
There are a number of things you can do to prevent build
up of dirt and prevent jewellery becoming tarnished. Namely;
Store jewellery carefully in its original packaging or
a jewellery box. Clean jewellery using warm water, mild
soap and a soft bristle toothbrush. Use a non abrasive
silver cloth or soft lint free cloth to polish jewellery
and remove tarnishing. Don't expose jewellery to harsh
chemicals or perfumes as this could cause damage and discoloration.
Don't wear jewellery when doing anything heavy duty and
avoid unnecessary knocks and scratches.
Beauty of gems
Although it is not one of the 4 C's, cleanliness affects
a diamond's beauty as much as any of the 4 C's (cut, carat,
color, clarity).
A clean diamond is more brilliant and fiery than the
same diamond when it is "dirty". Dirt or grease
on the top of a diamond reduces its lustre. Water, dirt,
or grease on the bottom of a diamond interferes with the
diamond's brilliance and fire. Even a thin film absorbs
some light that could have been reflected to the person
looking at the diamond.
Colored dye or smudges can affect the perceived color
of a gem. Historically, some jewelers' diamonds were misgraded
due to smudges on the girdle, or dye on the culet. Current
practice is to thoroughly clean a gem before grading its
color as well as clarity.
Cleanliness does not affect the jewellery's market value,
as jewelers routinely clean jewellery before offering
it for sale. However, cleanliness might reflect the jewellery's
sentimental value: some jewelers have noted a correlation
between ring cleanliness and marriage quality.
