Gold can come in different karats, so It’s important to understand what that means.
Karat is the term used to measure the purity of gold: the higher the karatage, the purer the gold. Gold in its purest form is not hard enough to be crafted into a piece of jewelry, so it needs to be mixed with other metals to make it wearable.The preferable options for jewelry, especially those that are encrusted with diamonds or other precious stones, are 14K and 18K gold.
Yellow gold is a classic color for engagement rings and it’s hypoallergenic. Maintenance wise, it is amongst the easiest of metals to clean.
