Gold at 120.55 euros per gram: up 5.4%, 6.6% below the top
Gold stands higher than six weeks ago but below the 129.04 euro peak of late August. Both figures, the sum behind them, and what you can do with it.

Questions about the knowledge centre
Are the articles and guides free?
Yes, everything in the knowledge centre is freely accessible. You do not have to register for anything and we never ask for an e-mail address. The site sets no tracking cookies either, so reading here leaves no trail.
Who writes these pieces?
Our own valuers, gemmologists and watchmaker. The name of the author is stated with every piece, together with the date and the reading time, so that you can see who stands behind the text and how current it is.
How often is the information updated?
Price-related tools always work with the rate of that moment. Articles and guides are revised as soon as regulation or market conditions give reason to do so, and the date of the piece tells you when that last happened.
May I quote from this?
Gladly, with an acknowledgement of the source and a link to the original page. That way your readers can check the context for themselves and see when the piece was last revised, which matters with figures that move.
