Below you will find some useful information to help you make a more informed decision when buying jewellery.
PRECIOUS METAL GUIDE
Yellow gold is a gold alloy that consists of combining pure gold, copper and silver. This precious metal is always measured in karats. Yellow gold is the only type of gold that can be 24 karats, as white gold and rose gold require other metals in order to achieve their unique colours. A
piece of yellow gold jewellery that is considered to be 24 karats means that it is 100% pure gold.
18K Yellow Gold: 75% fine gold, 15% copper, 10% fine silver.
14K Yellow Gold: 58.5% fine gold, 29% copper, 12.5% fine silver.
White gold is comprised of a percentage of gold mixed with white metals like palladium, silver, zinc and nickel. This combination gives white gold its durability and strength. White gold is measured in 24 parts and karats.
18K White Gold: 75% fine gold, 10 % copper, 8% nickel, 4.5% zinc, and 2.5% silver.
14K White Gold: 58.5% fine gold, 12% copper, 8% nickel, 6% zinc, and 4.5% silver.
White Gold will need rhodium plating as it has a yellowish or grey appearance, depending on the alloys used.
Rhodium plating does wear off and will need re-plating every 1-3 years.
WHAT IS ROSE GOLD?
Rose gold is a very popular alloy comprised of traditional yellow gold and copper, which lends a beautiful pinkish colour to the metal. Rose gold can also be known as red gold. However, this term is misleading, as rose gold and red gold have different gold and copper combinations.
Rose gold contains approximately 75% gold and 25% copper silver alloy.
Red gold has 58.5% gold and 41.5% copper silver alloy.
WHAT IS PLATINUM?
Platinum is one of the few precious metals that can be made into jewellery with a majority of its natural form. In fact, most platinum jewellery is made up of 95% and 90% platinum. Unlike white gold and traditional yellow gold, platinum is a strong and durable metal, which means it doesn't need to be mixed with other alloys to strengthen it. Additionally, platinum jewellery doesn't need to be plated with rhodium materials to give it its beautiful silver appearance. Platinum is an extremely difficult metal for jewellers to work with and will feel much denser on the finger. For these reasons, platinum is more expensive than yellow gold or white gold jewelry. It is hypoallergenic, which means that consumers with nickel allergies won't have to worry about an allergic reaction.
Mostly used platinum alloys are;
95.2% platinum, 4.8% iridium
95.2% platinum, 4.8% ruthenium
95.2% platinum, 4.8% cobalt
90% platinum, 10% cobalt
WHAT IS PALLADIUM?
Palladium is the latest precious metal trend to hit the jewelry industry. Similar to platinum, palladium is a precious metal that has almost 95% purity. Therefore, the majority of palladium jewellery will be almost entirely comprised of this precious metal. Like platinum, palladium is incredibly dense and strong, so it doesn't need rhodium plating. This makes it a great option for consumers who want to capture the look and feel of platinum jewelry.
When mixed with white gold alloys, palladium improves white gold alloys color.
WHAT'S THE DIFFERENCE BETWEEN KARAT AND CARAT?
Carat: A unit of measurement by which a diamond is weighed.
Karat: The measurement that shows the purity of the gold.
