|Always look for the carat mark on an item of gold jewellery, (if purchased from NWJ the SABS mark will tell you that it is to international standards) this will tell you that the piece is real gold and the percentage of pure gold it contains. Pure gold is rarely used because it is soft and easily damaged. Gold is alloyed with other metals, copper, silver, nickel and zinc, to give it strength and durability. 18ct gold is 75% gold and 9ct gold is 37.5% gold. The higher the carat the richer the colour will be and more costly the gold.
When purchasing jewellery in SA, ensure you only purchase from a member of the Jewellery Council of SA and look for the SABS hallmark from jewellers such as NWJ.
White GoldWhite gold is actually yellow gold that has been turned white by the addition of various other metals. It is often plated with rhodium to enhance the whiteness. The white metals; silver, palladium, and nickel are mixed with pure gold to produce white gold. White gold is then rhodium plated to enhance the whiteness as it has a slight overtone of yellow.
