Difference Between 9k, 18k Gold and Platinum

Gold is the traditional precious metal of choice for diamond and moissanite wedding sets. But with many different karat golds available, and the ever-tempting platinum bands, which is best for your engagement rings?

Gold karats refer to the amount of pure gold in a precious metal. 24k gold is 100% pure gold – you very rarely see 24k gold jewellery simply because it’s so malleable and can’t stand everyday use as moissanite wedding sets or other jewellery items.

The Charles and Colvard Forever One range features many 18k moissanite engagement rings. That means the precious metal is made from 75% pure gold, combined with other, quality metal alloys. With 18k gold you get a beautiful gold lustre but with durable, strong features from the metal alloys.

9k gold is comprised of 37.5% pure gold – it is more alloy than gold and thus less expensive. You’ll immediately notice that the quality just isn’t the same; it lacks the shine and warmth that you’ll see in an 18k gold engagement ring. Lily Arkwright are proud to sell exquisite 18k moissanite, emerald, rubies & sapphire Charles and Colvard Forever One and Chatham lab grown wedding sets.


What is Platinum?

Platinum is a light silver-coloured precious metal. Platinum rings have a different feel to gold rings, which tend to be more traditional. The silver colour can almost be described as white, as it’s amazingly light in colour. Just take a look at the Gisela Knife Edge Round Cut Solitaire moissanite Engagement ring to admire the bright glow of platinum.

The platinum precious metal used in the Charles and Colvard Forever One range is almost completely pure. Unlike gold, platinum is incredibly durable and doesn’t require an alloy-based composition.


Which Is Best for Moissanite Wedding Sets?

The low moissanite cost compared to diamonds means you probably have more budget to spend on higher quality precious metals to form the base of your moissanite wedding sets. Although, both diamonds and moissanite look exquisite set into both gold and platinum rings. Consider platinum if you want modern and contemporary jewellery, and 18k gold if you prefer a warm, rich and traditional style.

18k gold that’s well-made will be very durable and practical as a wedding ring as long as you take good care of it. Whether you opt for 18k gold rings or a stunning platinum set, your other half will be blown away by the beauty of our precious gemstones.
