Essential notes on precious metals


Sleek and elegant, platinum's natural white luster beautifully enhances a diamond's radiance. Thirty times rarer than gold and heavier, platinum is also the strongest of precious metals used in jewelry.

Prongs set in platinum are more durable than those set in gold. Still, gold luster is long lasting than platinum and requires less maintenance.

Platinum's high melting point made it a difficult metal to use, being another price increase factor for a platinum jewelry. Even with improved casting techniques, less expensive, platinum still remains expensive.

Yet its popularity continues to grow as consumers recognize its unique ability to bring out a diamond's brilliance, accepting its price. Nevertheless, a modern alternative is the white gold, rhodium plated, which is still expensive, but less expensive than platinum.

Unlike gold, platinum is often 90 to 95 percent pure, giving another reason to be more expensive per gram. It is frequently alloyed with gold, nickel, iridium, palladium, rhodium, or ruthenium. Platinum jewelry that meets the established standards is marked 900Pt, 950 Plat or Plat. In the United States, in order to be marked "Platinum" or "Plat," jewelry must contain at least 50 percent platinum.

Always look for the marking to ensure that the material is platinum and not white gold or another metal.

Platinum resists tarnishing, but as good as the gold does. It is also hypoallergenic which makes it perfect for sensitive skin.
