The Ultimate Guide to Metals

At Evorden, we offer different metals in different qualities and colours to fit every need.

Gold is the most malleable of the precious metals. It is a symbol of old-world romance, a nod to its rich history and heritage. It is naturally yellow, and is resistant to rust, tarnishing, and corrosion.

We work in 18k, 14k, and 10k gold. Pure gold is too soft to be worn everyday—it would bend and warp. Therefore, pure gold is mixed with other metals to ensure its strength and durability.

18k goldis 75% pure gold that is alloyed with other metals.
14k goldis 58.5% gold and similarly is alloyed with other metals to increase its strength and durability.
10k goldis less than 50% gold and more than 50% alloyed metals. The implications of having a greater amount of alloyed metals in your gold is that it will tarnish more easily.

A quick trick to remember the difference between kinds of gold is just to recall that the higher the number, the softer the metal, because it is more pure.

Color of Gold

The colour of gold is determined by the kinds of metal alloys included in the gold and their percentages.

Yellow gold generally accrues its glow from a very specific combination of reddish copper and greenish silver alloys. The higher the gold content, generally the more yellow the colour. For instance, 18k yellow gold is noticeably a brighter yellow tone, while 14k and 10k yellow gold is a softer, wamer tone. 

White gold is alloyed with metals that are naturally white and then is plated with an extremely tough element called Rhodium. Over time, rhodium can wear away and to keep your ring shining its brightest, you may need to have the plating touched up every few years. 

Rose gold, similar to yellow gold, uses the reddish hue of copper alloy among other metals to give it its rich blush colour. In the case of rose gold, 14k and 10k rose gold are a brighter, rosier colour, while 18k rose gold is a more muted tone. 

Gold is ranked 2.5-3 on the Mohs Scale of Hardness, where diamonds are ranked 10 as the hardest minerals on earth.


While gold is considered the most precious of metals, platinum is also a popular choice for engagement rings and wedding bands. 

It is often selected for its perceived value. Being less precious than gold, platinum is mined less and therefore is more scarce and as a result, has become technically more valuable on the market.

Aside from perceived value, the most common reasons to chose platinum are durability and its hypoallergenic qualities. It is a great choice for those that tend to react to gold or other metals.

For those whose metal of choice is generally a silver-tone but would prefer a low maintenance metal, platinum may be the ideal choice. It is naturally a bright silver colour and does not require plating or re-plating. Because of its durability, any scratches or patina can often be buffed out with a soft cloth. 
When making your decision, it is also worth noting that platinum is considerably more expensive to resize and adjust than gold.

Platinum is ranked at 4-4.5 on the Mohs Scale of Hardness, where diamonds are ranked 10, as the hardest mineral on earth.
