Platinum (symbol PL) was accepted as a precious metal after only the second
half of the 19th century and has a deep luster and a rich, white color. It is
rarer and heavier than all other precious metals and is considered to be more
valuable than gold. Platinum is often used to set the most valuable gems to
produce the finest jewelry. Platinum is one of the most popular metals of
choice for ring settings, because the strength and color of platinum enhances
the brilliance and depth of diamonds and precious stones.
Because of its density and weight, you can feel the difference between platinum
and other precious metals when comparing different types of jewelry. Platinum
is usually marked with the following symbols: PL, PT, PLAT, 950 or PT950.
Since platinum is the purest metal, it rarely causes an allergic reaction. In
the US and abroad, there is an increased interest in platinum jewelry, with
wedding rings being the strongest selling category. The platinum group of
metals (PGM), is comprised of six closely related metals: Platinum, Palladium,
Rhodium, Ruthenium, Iridium and Osmium.
