Platinum is pure, an expression of integrity, a reflection of inner truth. Platinum's purity endows it with a brilliant white luster. This helps to reflect the true radiance of diamonds. Because it is generally 95% pure (18 karat gold is 75% pure), platinum jewelry does not fade or tarnish and keeps its looks for a lifetime. Platinum's purity makes it hypoallergenic and ideal for those with sensitive skin.
Platinum is also in demand in other fields - it is used in industry, most notably in catalytic converters. Platinum also plays an important role in medicine. It is not affected by the oxidizing reaction of blood, has excellent conductivity, and is compatible with living tissue. Because of these properties, platinum is used for pacemakers. At present, more than 50,000 people are living healthily on pacemakers. Platinum is a life-saving metal for these people.
