Platinum is the rarest of all the precious metals. It is 30 times more rare than gold. It is 95% pure and consists of only 5% alloys such as palladium, iridium, ruthenium. The purity of the platinum makes it hypoallergenic, making it the perfect choice for people whose skin is reactive to other precious metals.

Platinum is highly dense, strong and durable and weighs more than an equivalent ring made in 18K gold. These factors make Platinum the most popular metal of choice for diamond jewellery, wedding band and engagement ring. Its greyish white sheen accentuates the sparkle and brilliance of a diamond. It does not require rhodium plating like White Gold; because of its rarity it is also the most expensive precious metal used for making jewellery.



Gold is very strong and also the most malleable of all precious metals. It is resistant to rust, tarnish and corrosion. To give gold its strength and wearability it is alloyed with a mixture of metals such as silver, copper, zinc, and nickel. Pure gold is much too soft for everyday wear.

The letter K, which stands for Karate, is placed in front of a number on the ring to indicate how pure the gold is or how much gold is in the mixture of metal. For example: 18K, 14K or 10K. Karate is expressed in 24th

Therefore: 24K is 100% pure gold

18K is 75% gold and 25% alloy with other metal to make it strong enough for everyday wear.

14K is 58.3% gold and 41.7% of other metals

10K is 41.7 % gold and 58.3% of other metals.

Yellow gold remains the classic choice for a wedding band and engagement rings. At DG & Co., we use 18K yellow gold, which is 75% pure gold alloy with copper with a red hue, and silver that contains a green hue. This combination of alloy gives the gold its rich warm tone and shine. Browse our stunning Yellow gold ring collection or Build your own ring

White Gold is the most fashionable and popular choice of metal for the wedding band and engagement ring. At DG & Co., our 18K white gold, 75% pure gold is mixed with palladium, and other white metals then it is plated with an extremely hard element call rhodium. This mixture allows our white gold to maintain its silvery white appearance over time, however through wear and tear white gold will require rhodium plating for it to maintain its shiny white character.

Rose Gold is the least common of all the gold used to make jewellery. However, it has become quite popular recently. Rose gold is an alloy of pure gold and other metals such as copper to give it its rose color, strength and durability making it ideal for jewellery. It can be made into 18K, 4K and 9K which refers to the amount of pure gold in the alloy. Rose gold can vary in color depending on its gold content. Therefore, an 18K rose gold will have a richer red color than a 9K rose gold. At DG & Co., we use 18K Rose Gold for our wedding bands and engagement rings.

Titanium is the most popular choice of metal for men's wedding band as it is the toughest metal around, and it is also lightweight and has a beautiful natural grey color. Titanium can only be made by machine because it is a very tough metal to work with. Therefore, the rings are only available as ready made rings. Browse our Titanium ring collection

Jewellery Care: It is crucial to keep gold away from harsh chemicals such as chlorine and other household cleaning products to avoid daily abrasion and to prolong the luster of the metal. We recommend you clean your jewellery using a solution of warm water and detergent-free soap with a soft bristle brush. Make sure to store your jewellery away in a soft cloth bag or box when not worn to protect it from the daily exposure of elements.
