ALL ABOUT PLATINUM & GOLD!

PLATINUM

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.

In the United States platinum is usually marked PT or PLAT. In Europe, it is marked 950 or PT950

GOLD

Gold is a beautiful and imperishable metal. It was one of the first metals to be mined because it commonly occurs in its native form (100% Pure).

Pure (100%) gold is too soft, and it is usually mixed with other metals (gold alloys) to make it stronger and more usable for jewelry.
The metals that are mixed with pure gold for strength can also modify the color of gold resulting in different shades of yellow, white, and pink.

PRICE - The following are some of the factors that determine the value of a gold jewelry piece.

• weight: gold is sold by weight - grams(gr) or pennyweights(dwt), the heavier the piece, the higher the gold content, therefore it is more expensive.
• design: designer jewelry is more expensive, especially if it is a one of a kind piece.
• finish: special finishes to the metal such as matte, or sand-blasted finish add to the cost of the gold jewelry piece
