What is 18kt gold

What is 18kt gold?  I get this question sometimes from customers who are trying to decide which metal to choose for their piece of fine jewelry. Here is what I usually say when asked what is 18kt gold. 18kt gold consists of 75% pure gold mixed with other alloys to make up the remainder balance (copper or silver for example). You get the 75% because 24kt is pure gold (18/24 giving you 0.75 or 75%).

14kt gold is 58% gold with the balance consisting of other alloys. 18kt is a more pure gold than 14kt and therefore can be a bit softer than 14kt gold. To me, 18kt yellow gold has a richer feel than 14kt yellow gold since it has a higher pure gold percentage. 18kt gold jewelry should be stamped with 18kt, 18k, or some similar variation. It could also be stamped 750 or 0.75 referring to it being 75% pure gold. This stamping is most commonly on the inside shank of the ring or on a clasp for a necklace for example. 18kt gold is quite often the metal chosen for jewelry including engagement rings and wedding rings.
