One of the great qualities of gold is its malleability. This, combined with its physical beauty and resistance to corrosion, makes gold the ultimate creative medium. Pure gold can be considered too soft and delicate for use in jewelry, so it is often combined with other metals for greater strength. Gold comes in a variety of karatages to provide a greater range of price for people on tighter budgets. The most common and popular karatages for gold jewelry are as follows:
Today the metal’s traditional golden hue can be subtly and changed. The modern alloying process, undertaken to increase durability and wearability, now combines pure gold with other metals to create a variety of colors. Mixing in white metals, such as palladium or silver in combination, creates white gold. Rhodium plating is another common addition to give gold its white color. The addition of copper results in the soft pink complexion of rose gold. And gold can now be created in a spectrum of other colors, such as green, purple and even black.
