How is scrap gold value calculated per gram in the UK?

Scrap gold value is determined by taking the live spot price of pure 24k gold per gram and multiplying it by the metal's purity percentage (for example, 9k gold is 37.5% pure, 14k is 58.5%, and 18k is 75.0% pure). The EXE Jewellers live scrap calculator updates to spot market feeds automatically.

How do you measure a ring size using a phone screen?

Open the calibrated screen ring sizer on your phone or tablet, place an existing ring that fits onto the circular guide on your display, and adjust the slider until the glowing circle precisely matches the inside edge of your ring to view your exact UK and US size.

What do UK gold hallmarks mean?

A standard British hallmark contains three compulsory symbols: the Sponsor/Maker Mark, the Millesimal Fineness mark indicating metal purity (such as 375 for 9ct gold or 750 for 18ct gold), and the Assay Office Mark (Anchor for Birmingham, Leopard for London, Rose for Sheffield, Castle for Edinburgh).
