Question
Is there a difference between 18K and 18ct?
Hello Debbie,
Well its a common mistake that people make: 18 karat is the correct way to express the fineness of gold that is 18/24ths or three quarters pure gold In Europe it is often marked 750 denoting that it is 18 karats in finness.Whereas the term " carat" refers to gemstone weights..So anything jewelry is often written using the terms kt, and ct. interchangeably by people that don't realize the difference or correct term for metal ( karat) versus the correct term for gemstone weights (Carat). I hope this clarifies it for you.
Best regards, Ari
