Diamonds in Yellow

This collection celebrates 18ct yellow gold, always so classic and increasingly on-trend.

18ct gold contains 750 parts per 1000 of pure, 24ct gold. The remaining quarter of the alloy will be made up of other metals, usually including silver or copper.

There is a common misconception that 9ct gold is 'harder' than 18ct gold, and therefore harder wearing. In fact, the opposite is true: Using the Vickers Scale, 9ct gold's hardness is between 80 and 120 (depending on the other constituents of the alloy), whereas 18ct gold scores between 135 and 165. It appears that the myth arose from marketing campaigns for 9ct gold when prices soared after the First World War.

Gold is a noble metal, and extremely durable against oxidisation, tarnishing and chemical corrosion.

At Ogdens we have been selling gem-set jewellery in 18ct gold since we were founded in 1893, and rarely has this style been more popular than now.

The cushion-shaped cluster ring actually features a round brilliant cut diamond weighing 0.70cts to its centre - a contemporary twist on the classic, time-honoured cluster ring style.

The single stone diamond pendant on the spectacle-set diamond and yellow gold chain is a true showstopper. Among the rings is a wonderful rectangular cut piece, with a high-specification G colour VS2 centre diamond.
