| The platinum group metals
(PGM), comprise six closely related metals: Platinum, Palladium,
Rhodium, Ruthenium, Iridium and Osmium.
Platinum has a deep luster
and a rich, white color. It is rarer, heavier and denser than
all precious metals and considered to be more valuable than
gold.
Platinum is often used to
set the most valuable gems to produce the finest jewelry because
it holds gemstones most securely and it neutral color enhances
the brilliance and depth of diamonds and precious stones.
