What happens to lớn the colour of gold?
Gold is available in three colours: yellow, white, và rose.
Over time, the colour of gold jewellery can change due to wear and chemical reactions with the environmental elements it comes into liên hệ with. The biggest change will happen lớn a white gold ring.
White gold: The most delicate
White gold isn"t completely white, but more a yellowish white.
This is because 18ct gold has a nội dung of 75% pure yellow gold and 25% other metals. In the case of trắng gold, the 25% is a phối of metals employed to lớn make the finished sản phẩm as white as possible. However, even with these elements, a total trắng hue is rarely achieved. Therefore, white gold is often plated khổng lồ make it appear even whiter.
There are two types of 18ct white gold generally used in jewellery making. The first, & our preferred option, is “high palladium white gold”, which is naturally whiter. Palladium is an exceptionally trắng metal, so when the 25% of other metals has a high palladium content, a seriously white tone can be achieved.
"This palladium set will appear white for much longer, even after the plating begins to lớn wear thin, as the gold underneath is naturally whiter."The other is "standard trắng gold", coated in rhodium. In this case, the 25% of other metals is a phối of cheaper elements that aren"t as trắng as palladium. So, when the rhodium plating wears off, the layer revealed underneath is yellowish-white in hue.
In both cases, every few years, you can get your white gold jewellery re-dipped in rhodium to maintain its silvery appearance and make it shine lượt thích new again. Most jewellers will bởi vì this for free, or very affordably.
Other metals need care, too
Yellow and rose gold can also change colour due to oxidation or chemical reactions.
Oxidation is a process caused by simple daily exposure khổng lồ oxygen, which can eventually affect the colours of different precious metals. For example, this is what causes silver to turn black. We always advise that keep your silver jewellery in zippy bags, away from humidity & air. This will keep your jewellery in shape for much longer.
If you work around a lot of heat and fire (in a kitchen, in a forge), then you could be exposing your ring to lớn too much heat, which could also change its colour. Sometimes even the chemicals in your perfume or soap can cause discolouration.
Acid from your skin or from cleaning agents can dull the colour of gold và even discolour it in places. If you notice stains that simply won’t go away, you may need khổng lồ have your jewellery cleaned and re-polished by a jeweller. These types of tough stain can occur when the metal alloy in the gold jewellery (the 25%), like copper in rose gold, has reacted differently than the gold itself (the 75%).
Platinum
Platinum is a super stable metal và so a platinum wedding ring will retain its colour from the day it"s slipped onto your finger for the first time and years beyond that. This resilience is the reason that platinum is the traditional choice for bridal jewellery; it"s perfect from everyday wear.
On the other hand, platinum does appear slightly less sparkly & shiny than brand new white gold, so it might not catch your eye in the cửa hàng in the same way.
