Platinum is a natural white metal, although it is not as reflective as silver or white gold, it doesn’t fade or tarnish. Platinum is also 95% pure which means it is hypoallergenic and ideal for those with sensitive skin.


Titanium is a silvery to dark grey, lustrous metal, traditionally not associated with jewellery. It is stronger than steel and much lighter than gold and silver.

White Gold

Gold is naturally yellow and white gold is the term used for an alloy of gold with a white metal, such as palladium. The highest quality of white gold is a gold and palladium alloy of at least 17 carats, sometimes with traces of platinum to increase its weight and durability.

Carats - Gold

Gold in jewellery is alloyed with other metals to increase its hardness and durability. The purity of gold in proportion to these other metals is measured in Carats (written as ct or K) with the purest gold being 24ct. All other gold are measured as a proportion of 24, so 9ct gold is 9 parts gold out of 24, whilst 18ct gold is 18 parts gold out of 24.

Carats & Points – Diamonds

Rather confusingly, the word Carat is also used as the scale to measure the weight of a diamond. One carat is 0.2 grams of a diamond’s actual weight. Smaller diamonds are sometimes expressed as points rather than carats, and 100 points equals one carat. As larger diamonds are more rare than smaller ones, they are more expensive, so often a one carat solitaire ring is more expensive than one made up with several smaller diamonds, even if their combined weight equals more than one carat.
