Essential Facts about platinum
| |
Platinum
is a beautiful silvery-white metal, when pure, and is malleable
and ductile. The metal does not oxide in air.
Because it is generally pure 95% pure (18 karat gold is 75%
pure), platinum jewelry does not fade or tarnish and keeps its
looks for a lifetime.
|
| |
Scarce
- Platinum is 35 time rarer than gold. It is estimated
that if all the platinum in the world were poured into one
Olympic swimming pool it would be scarcely deep enough to cover
your ankles.
|
| |
Durable
- Platinum's density and weight make it more durable than any
other jewelry metal.
|
| |
Pliable -
Platinum is so pliable that just one gram of the metal can be
drawn to produce a fine wire over one mile long.
|
| |
Availability - Platinum is available in many forms
including foil, sheet, wire, insulated wire, gauze, powder,
sponge and metal. See various
forms of platinum.
