Know your alloys and colors

Pure 24-karat gold appears yellow but it isn’t always practical to purchase pure gold because it is soft, malleable and expensive.

This is why, as we’ve discussed, jewelers have come up with a method to mix gold with other stronger metals. Since these items are usually not more than -karat gold, the other metals influence the yellow color and yield an alloy with a different color.

When buying gold, you are not only limited to the golden yellow color. Here are some of the colors of gold you need to know:

• Yellow gold – This is the color that comes to mind when we say gold. In fact, the word ‘gold’ is in our vernacular as a color, likened to honey or sunshine. However, not all gold yellow jewelry is actually gold. As you know, plating is common to golden jewelry and sometimes it is intentionally done to keep the yellow gold appearance

• White gold - This looks like a brighter version of silver. It is as popular as yellow-gold for engagement rings. White gold is sometimes paired with yellow-gold in items more commonly known as two-toned. White gold is made of white metals (i.e. palladium, nickel or manganese) that are stronger than gold.

• Rose gold - A gold alloy with a pinkish hue, rose gold has become an engagement ring sensation! To achieve the pink blush, copper is added to gold, often 14 karats or 58.5% purity. The highest karat version of this alloy is known as Crown Gold, made with 75% gold and 25% copper.

• Green gold – This is one of the rarest varieties that is made of gold mixed with silver. It comes with a bright greenish yellow hue and compliments green stones like emerald and peridot extremely well. Green gold is mostly produced in labs but is very rare and very expensive. Green gold known as “electrum” can be mined naturally. Only very few jewelers are privileged to see them so this isn’t something you would typically come across when gold shopping.
