Platinum makes this ring with
intricate delicacy possible! More on this design
Platinum Jewelry - Tips, Tricks & Care
Platinum Jewelry is a pleasure to wear
and a pleasure to create with. Platinum is more pliable than gold
and as such lends itself to a variety of design options that other
metals simply do not. Platinum is more durable than other metals.
Platinum is stronger, wears better and lasts longer. Investing in
platinum jewelry is like purchasing anything else of higher quality, you
simply get more for your money when you buy platinum because it will
wear better, last longer and requires less service.
Platinum is Purer than Gold
Most platinum jewelry is 90 - 95%
pure, whereas 18 karat gold is 75% pure and 14k gold is only 58.5% pure.
All of the various alloys used to manufacture fine jewelry contains a
blend of other metals, platinum simply has less. The presence of
other alloys in white gold is what causes it to oxidize, face and change
color over time. Because platinum is purer than gold, it doesn't
fade or change color and it retains it retains a polish longer.
The pure white luster of platinum reflects the true brilliance of
diamonds and provides the best setting for most precious gems. The
combination of platinum and yellow gold creates a perfect balance of two
tonal values for people who prefer warmer tones.
Platinum is Hypo Allergenic
Platinum's purity makes it the perfect
alloy for people with sensitive skin. Because platinum is more
pure than gold and has been mixed less metal than other alloys used to
create jewelry, it does not cause allergic reactions. People who
suffer from allergic reactions when they wear gold jewelry in their ears
or who experience rashes on their fingers when wearing gold jewelry
should consider platinum.
Platinum is Rarer than Gold
Platinum is thirty five times rarer
than gold. Platinum is found in only a few places throughout the
world. At present, most platinum mining is done in South Africa
and Russia and to a lesser extent in Zimbabwe, Canada and South America.
It takes eight weeks and 10 tons of ore to produce a single ounce
(31.1 grams) of platinum, whereas only five tons of ore are mined to
produce the same amount of gold! And for every ten gold mines that
exists in the world, there is only one platinum mine. During the
average year, approximately 2,700 tons of gold are used in the process
of manufacturing jewelry but only 88 tons of platinum are used to make
jewelry. Platinum seems to cost more than gold at first glance,
but upon further study it becomes clear that the higher cost of platinum
is simply due to the fact that platinum is purer than gold and much more
rare.
The Density of Platinum Makes it more
Durable
Platinum's density and weight make it
more durable than other jewelry metals. A six inch cube of
platinum which measures approximately 15 centimeters cubed weighs 165
pounds (75 kg) which is almost as much as the average man!
Platinum is also resistant to heat and acids and has a higher melting
point than gold (3,223°F / 1,768°C) and
requires special equipment for casting into jewelry. Platinum
doesn't wear away as other jewelry metals do, it holds diamonds and
other gemstones firmly and securely. All metals can be scratched
and displaced however, a scratch on a platinum piece of jewelry is
merely a displacement of the metal. The primary difference between
gold and platinum jewelry in terms of the displacement of metal caused
by a scratch is that with platinum the metal has merely been relocated
whereas gold has a tendency to wear away and decrease in volume.
If visible scratches appear on platinum, it can be re-polished by a
qualified jeweler without substantial loss to the piece. Perhaps
this is why platinum has been used to fashion the jewelry for some of
the world's most precious gems including the Koh-I-Nor Diamond which is
part of the British Crown Jewels.
The Versatility
of Platinum
In addition to
its strength and durability, platinum is also extremely versatile.
Platinum is so pliable that a single gram of platinum can be drawn into
a fine wire that stretches out for more than a mile (almost 2 km) in
length while retaining it's strength. This quality has enabled
jewelers the world over to produce exquisite detailed designs in
platinum that could not be made in any other metal.
General Care for Your
Platinum Jewelry
-
Store
platinum jewelry separate from other jewelry items so that they do
not scratch or get scratched by your other jewelry items.
Place your jewelry in a jewelry box or a chamois bag.
-
Store your
platinum jewelry and other precious items in a safe place such as a
personal safe or safety deposit box.
-
Maintain
adequate insurance for your valuables. If you are unsure about
the value of your platinum jewelry and other valuables, take then to
an independent appraiser for valuation.
-
Clean your
platinum jewelry periodically. This will ensure its fine
appearance and will help it last.
-
Clean
platinum in the same way you clean other fine jewelry - using a
pre-packaged jewelry cleaner or by soaking it in a mild solution of
50% ammonia and 50% warm water and then gently rubbing it with a
soft cloth. Note that harsh chemicals such as ammonia should
not be used on gemstones other than diamonds because it may damage
them - consult a jewelry professional in-person for specific
guidance in this matter as it applies to specific jewelry items.
-
Have your
platinum jewelry polished and cleaned by a qualified jeweler twice a
year and more often if scratches appear. Remember that all
metal can be scratched, however with platinum the metal has merely
been displaced.
-
Take your
platinum jewelry to a qualified jeweler twice per year for
inspection. Only allow a trained professional jeweler to work
on your platinum jewelry! Adjustments, resizing, polishing and
cleaning of your platinum jewelry should be provided by a trained
bench jeweler. We can't tell you how many times we have
repaired platinum jewelry that has been resized using white gold by
some jeweler who should never have been working on a platinum
jewelry item to begin with!
-
Be aware
that over time platinum develops a natural patina that many people
prefer over the "just polished" appearance of platinum. When
this happens to your platinum jewelry you may take it to a qualified
jeweler and have the item polished for that "high gloss" look or
simply ask them not to remove the patina if that is your preference.
-
Do not wear
your platinum or other fine jewelry when doing home cleaning,
gardening, or other types of heavy work or manual labor.
Jewelry is designed to be decorative, not indestructable.
-
Do not wear
your platinum or other fine jewelry when working with bleach or
other harsh chemicals. Although the chemicals may not affect
the platinum, they may discolor diamonds and other gemstones and can
cause an allergic reaction with your skin if trapped between the
ring and your finger ☺

Properties
or Platinum:
Catalyst, hypoallergenic, resistant to heat and acids.
-
Platinum
group metals: Ruthenium, Palladium, Rhodium, Iridium, Osmium.
-
Measuring
the perfection of Platinum: 1,000 parts - 100% platinum.
While the gold content of a jewelry item is indicated
by a karat stamp, the content of platinum is displayed in parts per
thousand. This is because gold is measured in parts per hundred
and platinum is measured in parts per thousand. Thus while gold
jewelry might be stamped as being 10k, 14k, 18k or 22k, platinum will be
stamped 500, 850, 900, 950, etc. Note that if the alloy content is
stamped on a jewelry item, then by U.S. Law the manufacturer of the item
must also be identified by a stamp that designates their identity in the
form of a Hallmark which will appear along with the alloy stamp and look
similar to the old fashioned brands that ranchers stamped on their
cattle.

While we feel that platinum is the
perfect accompaniment for the diamonds listed in our
Private Reserve we
recognize that some people simply prefer the look and feel of gold.
For this reason, we offer most of the designs we represent in platinum
in white and yellow gold and vice versa. If you see a simple
design on our site pictured in one metal, but would prefer it in
another, simply ask and 99% of the time we will be able to oblige you.
Intricate designs and those which encompass hand etching however may
only be available in platinum, because platinum holds the pattern better
and can be used to make designs which are not possible in gold.
May we help you find the diamond of your dreams?
