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 option of ever-tempting platinum bands, which is best for your engagement ring?


What are Gold Karats?

Gold karats refer to the amount of pure gold in a precious metal. 24k gold is 100% pure gold – this is seen rarely due to the fact that 24k gold jewellery is largely malleable and is hard to maintain in everyday use, in the way that moissanite wedding sets or other jewellery items are able to.

The Charles and Colvard Forever One range features many 18k moissanite engagement rings. This means that the precious metal is made from 75% pure gold and combined with other high quality metal alloys. With 18k gold, a beautiful gold lustre is still guaranteed, as well as durable, strong features from the metal alloys.

9k gold is comprised of 37.5% pure gold – it is more alloy than gold, therefore making it less expensive. You’ll immediately notice that the quality isn’t the same and lacks the shine and warmth that you’ll see in an 18k gold engagement ring. We are proud to sell exquisite 18k moissanite, emerald, rubies, and 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, due to its amazingly light colour. 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 cost of moissanite compared to the expensive cost of diamonds means you probably have more budget to spend on higher quality precious metals to form the base of your ring if you choose a moissanite wedding set. Both diamonds and moissanite look exquisite when set into both gold and platinum rings. Consider platinum if you desire 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.
