Rose Gold, the Power of Pink: How is it Made?
White metal, whether platinum, white gold or silver, has for many years been rock star of desirable jewellery designs. But, there’s a new kid on the block and their name is Rose; rose gold that is!
Often seen in antique jewellery, rose gold was, for many years, the “must-have” for lovers and collectors of antique jewellery and, therefore, suffered from being seen as being old-fashioned with a been there, done that reputation.
Well, no longer! With a seeming relentless appetite for vintage jewellery comes a growing appreciation of rose gold Ask any assayer (we’re getting a bit techie here), someone who works with metal, and they’ll tell you that gold is yellow. I suppose the clue is in the name. Whilst we refer to coloured golds as white gold, red gold, green gold – yes, that is possible – what we’re really talking about is a gold alloy which, because of the other metals used in the alloy gives another colour. For example, in our case of “rose” gold we mean gold that has been alloyed with silver, copper and zinc.
The amount of copper added determing the shade of the rose but, in the case of fine jewellery created from higher carat gold, the variation of tones of rose is limited. This is because the percentage of gold in each carat, ie. 9ct, 18ct, is legally determined So, with higher carat alloys, for example 18ct gold must contain 75% of gold within the alloy, there is only so much “room” left for other metals which can be used to affect the end colour.
