Precious Metal Guide

At Novita, we proudly use the highest grade of alloys for our exclusive premium collections of jewellery and lab grown diamond rings, using a secret alloy formula for our 18K gold and platinum manufacturing of our timeless pieces. We wanted to create a helpful guide to help you choose which precious metal is right for your dream diamond ring or beautiful jewellery.

Platinum 950

Due to the beauty, durability and naturally lustrous white look of Platinum, this is our preference for engagement rings and wedding bands. Platinum is a rare and valuable precious metal. Its rich and even white colour magnifies the sparkle and brilliance of diamonds that are set in this metal.

Platinum requires less maintenance as it will never fade or change colour. Pieces in platinum are more costly than 18K white gold due to more labour required in the manufacturing. Platinum is more dense and uses a higher purity (95%)

18K White Gold

Due to the similar white appearance of white gold to platinum, it is a good alternative and costs less. 18K gold has 75% gold and 25% other metals that give it a white colour and make it stronger. Our 18K white gold pieces are finished with a plating of Rhodium which is a very rare metal that gives a white shiny finish.

Overtime, 18K white gold may develop a slightly yellow under stone, despite being a strong metal. This is because gold is naturally yellow and to make white gold, the natural yellow gold needs to be mixed with white colour metals. Therefore it needs to be re-rhodium plated every few years to restore the ring to its original beauty

18K Yellow Gold

The natural colour of gold is yellow. 18K yellow gold has 75% gold and is mixed with other metals to give it strength, maintaining its classic look and makes it ideal for lifetime of wear.

18K Rose Gold

Rose gold is as strong as yellow gold and it will never rust or tarnish. Rose gold also known as pink gold or red gold is made from 75% gold and 25% copper that gives it a pink tone while adding strength. The result is a pink gold colour that suits many styles and skin tones.
