Most timepieces & jewellery are made of either platinum, yellow/pink or white gold.
White Gold
All gold is yellow. That’s its natural colour. White gold has simply been mixed with other alloys to make it look white. But over time it may lose its whiter colour and turn a yellowish colour. Which is why most white gold is electroplated with a precious metal called “Rhodium”. The purpose of rhodium plating is to give white gold a whiter and brighter finish. Rhodium is also believed to add a somewhat harder surface to the gold, which may give white gold a higher resistance to scratching. Platinum, however, is a naturally occurring white metal.
In all fairness to gold, platinum may also develop a slightly dull look after normal wear. This dullness is known in the industry as a “patina” or slightly dull finish and may be removed by minor polishing.
The Markings or Hallmarks of Platinum
The “hallmark” of the wristwatch/ring is intended to reveal the metal that makes up the wristwatch/ring and is typically stamped on. For instance, the markings that denote platinum may be: Platinum, Platine, Pt950, 950PT, 950Platine, Platine950, 900Pt, Pt900 and 900Platine.
Platinum the Purer Metal
Platinum and gold will always contain other metal alloys. The question is, how much gold or platinum are you getting?
For instance- 950Platinum is 95% pure platinum and 5% alloy. 900Platinum is 90% pure platinum and 10% alloy.
Gold on the other hand is mixed accordingly- 18K gold is 75% pure gold and 25% alloy and 14K gold is approximately 58% pure gold and 42% alloy.
What is the rest made of? Platinum is commonly alloyed with one of three other precious metals from within the platinum metal group- iridium, ruthenium or cobalt. Because of these alloys, platinum in hypoallergenic.
Gold is usually alloyed with common metals like nickel, copper, zinc and or palladium. A good number of people may have allergic reactions to nickel in gold.
