Learn about Metals



Gold is one of the heaviest metal known and an extraordinary heritage with distinctive qualities. As a lasting element found naturally in a bright yellow dense in colour, it is resistant to rust, tarnish and corrosion.  However it is as well the most malleable of all precious metals. This gives the gold strength and durability to alloy with a mixture of metals like silver, copper, nickel and zinc.


Karatage (K) represents purity, or how much of the metal in a piece of jewellery is gold.  Pure 100% gold is 24 karat by definition.18K gold is composed of 75% gold, which is alloyed with other metals.  It is ideal for fine jewellery making. 14K gold is composed of 58.3% gold and 41.7% of other metals.


MOHSTEN offers 18K gold jewellery which we believe it is strong enough for everyday wear. 


Colour of Gold

Two colour gold factors: The type of metal alloys with and the percentage of each metal alloy.


Yellow Gold

The natural gold and colour-saturated alloys give the jewellery its rich shine.  Yellow gold is pure gold mixed with alloys.  The alloys used are usually copper and silver.  Zinc and nickel may also be used as alloys. 


A mixture of alloys and pure gold gives this precious metal its signature warmth.  Yellow gold needs to be polished regularly to retain its shine and it is softer than white gold therefore more vulnerable to scratches and marks.


White Gold

White gold is made with an alloy of gold and some white metals in nature such as silver; nickel, manganese or palladium and plated with an extremely hard element called rhodium.  Although rhodium is strong, it may wear over time.  Replating is a simple process that can restore whiteness to your jewellery.


White gold is more long-lasting and scratch resistant than yellow gold, thanks to the stronger alloys.  Yet, white gold is still lightweight and soft enough to work with and is easier to re-size if necessary.


Rose Gold

Rose gold has a beautiful pink hue created by using gold and copper alloy as well as some silver.  Rose gold, also known as pink gold and red gold.
