Besides gold and
platinum, today science gives us a much wider choice of metals for
our diamond rings. These are as under.
Silver: This
metal has been in use for thousands of years and is opted by many
today. As it is too soft for usage in its pure form, this is alloyed
with other metals for strength. Its popular alloy form is sterling
silver, where 92.5% of pure silver is alloyed with 7.5% of metal. Its
greatest benefit is that the metal is highly affordable. However
silver is easily prone to tarnish and needs regular maintenance. The
metal has to be regularly polished or the tarnish can cause permanent
damage.
Stainless steel:
This is fast gaining popularity among the contemporary crowd who
are seeking for a new look. The benefits of stainless steel are its
strength and that it does not rust or corrode as easily as steel. The
chromium present in this prevents oxidation which keeps rust and
stains away.
Tungsten: This
is a relatively new metal in the diamond industry and is popularly
referred to as the ‘permanently polished metal'. Its pros
include resistance to corrosion, high density and strength. This
metal is four times harder than titanium and retains a permanent
shine with little maintenance. Tungsten carbide rings can also be
opted for, whereby tungsten and carbide powders are combined at high
temperatures. TC rings are scratch proof as compared to tungsten
rings. Because of their sleek and simple look, they are an ideal
choice for men's engagement rings. However on the flipside, its
strength does not allow for resizing rings as the metal is difficult
to bend. Also in case of emergencies, a medical professional may be
needed to remove the ring, as standard ring cutters would not work.
Titanium: After
gold and platinum, titanium is the third most popular alternative for
mounting diamond rings. This is because the metal is immune to
corrosion from salts, acids and alkalis, is hypo allergic and non
magnetic. It has the strength of steel, but is half as light and is
highly durable. Black titanium can also be availed in light or dark
shades of gray.
Palladium: This
metal is pure white in color and looks much similar to platinum. It
also resembles white gold, but is much stronger than it and is
available at similar costs. Its benefits include high strength, hypo
allergic nature and durability. Palladium is also much lighter in
weight. In jewelry it is used in its alloyed form that usually
includes 95% of the pure metal along with 5% of metal from other
platinum groups (viz iridium, ruthenium).
Zirconium: This
is an appealing metal for consumers seeking interesting metal
alternatives in their diamond jewelry. While this metal is grayish
white in color, a natural black is obtained through heat treatment
whereby the oxide layer converts into zirconia. Its benefits include
high strength, scratch resistance, a surface transformation ability
and hypo allergic qualities.
Rhodium: This
metal is silver white in appearance and is a member of the platinum
family. Its benefits include high strength, great durability and also
good reflecting properties. In jewelry, this metal is usually
electroplated on surfaces such as white gold and platinum. It can
also be applied to silver in order to protect the latter from
tarnish. While this metal is used to symbolize wealth, one must
remember that rhodium compounds can stain the skin.
Niobium: This is
a relatively new metal in the market and is being used by many
jewelry designers today. It belongs to the titanium and tungsten
family of reactive metals. In its pure form, the metal is light gray
in color and has a good luster. Besides usage of its natural color, a
wide range of colors can also be anodized on its surface. Shades
include purple, turquoise, fuchsia, blue, yellow, black, gray and
also rose. It is highly resistant to attack by chemicals, is
malleable, hypo allergic and rare in occurrence. Price wise the metal
is slightly expensive as compared to silver.
Besides the above list
of metals, buyers can also choose for two tone or multitone rings
where different metals are combined together for added affect.
Besides the traditional silver and gold, different shades of gray can
also be opted for. Carbon fiber, in its various shades, can also be
used with metal and diamonds for added affect. As one can note, the
choice thus, is endless. However, each metal has its strengths and
weaknesses and needs good maintenance for a long life of beauty and
strength.
