Understanding Your 750 Gold Bracelet: What Does It Mean?

Question
I have a gold bracelet, it is european, my grandmother left me, it is marked with the # 750 can you tell me what this means? Thank you, Tina

Answer
Hello Tina,
What your grandmother left you is an 18 karat gold bracelet.18kt gold is 75% pure gold the balance alloy made of silver and copper depending on the colour and may have traces of other metals too as a colouring or strengthening  additive or deoxidant. 14 karat is 57% gold ( or less), sometimes expressed as 570 gold and 22kt is 85 % pure gold sometimes expressed as 850 .
I hope this helps you  know your golds.Generally european gold jewelry  made  before the 1970's is expressed with the  respective percentages, after that period it was standardised all over the  free trade world and  is  expressed in karats i.e.- 14 kt, 18 kt, 9 kt  in the UK and overseas ,10kt in the USA, and 22kt most commonly.
If you have a piece marked 14/20 g, or 12/10 GF it indicates the piece is 20% gold filled which is a bonded layer of 14  or 12 kt solid gold over a base metal,usually brass though in Vermeil its over fine silver (.999 is fine silver .950 is sterling) and is usually marked 22 kt V, or D'ore..I hope this provides all you ever needed to know about precious metals markings!
Best regards, Ari
