White Gold Vs Yellow Gold Vs Rose Gold October 25, 2017 – Posted in: Jewelry Blog

It seems a little odd, somehow, when we talk about different colors of gold when, in reality, only yellow gold is ever mined. So how – and why – did we end up with other colors, and what difference does it make to a ring? In terms of the difference, we’re mainly talking about aesthetics. Some people have a preference, and some stones work better with one color than another. But there are one or two other considerations, if gold is the chosen metal for any ring.

Yellow Gold

Yellow gold, the “real” version of the precious metal, is rarely used in its purest form. We do talk about 24 karat (24k) gold, but as this purity is also what makes gold the most malleable metal known, it can cause problems with wearing and mis-shaping even with great care.

Of course, yellow gold is a beautiful metal for rings and other jewelry, and it is highly resistant to corrosion as well as being non-toxic and hypo-allergenic in pure form so ways were found to make it more usable in jewelry manufacture.

The lower the official rating (eg 14k, 9k), the lower the purity. At anything less than 24k, yellow gold is alloyed with other metals such as nickel, zinc, palladium, copper and more. The numbers are important, as gold is considered to have 24 “parts”. At 9k, therefore, the metal is only 37.5% gold (100÷24*9=37.5). To remove some of the softness of pure gold, it is common for the highest grade of gold used in modern ring manufacture to be 22k, with the other 2 parts being copper. 18k is usually the most traditional grade of gold on the market.

However, it hasn’t always been the case that gold in high quality jewelry has been alloyed with something else. It once was common for 24k gold to be used routinely for most rings especially wedding but, to avoid high costs, the rings were often quite narrow and thin. If a wedding band from, say, a century ago were to be viewed now, it’s likely that at least one part of the band would be worn very thin, and may even have snapped due to the constant wearing.

But, whatever the grade, there’s no denying that yellow gold makes for an exquisite ring, and pairs very well with diamonds a little higher up the color scale, as the combination of the yellow gold, and the slight yellow tint of the diamond give the whole piece a warm feel that is in stark contrast to the coolness that naturally goes with colorless diamonds and white metal. Using yellow gold can also look spectacular when against olive or darker skin tones.

White Gold

White gold is often used as a less expensive substitute for platinum, as it bears very similar color properties, but it isn’t without its own inherent issues.

Originally, yellow gold was alloyed with nickel in a ratio of 9:1, as the nickel acts as a bleaching agent for the yellow of the gold and also served to make the metal more durable. The downside to this practice is that, even in such a low percentage of the overall weight, nickel can cause skin irritations for around 1 in 8 people. As a result, many countries now have stopped using nickel altogether in their white gold jewelry.

An alternative formula was sought, of which a gold, palladium and silver alloy is now commonly used. As palladium and silver are also precious metals, the reduction in price over 24k gold isn’t as great as when nickel is used, but it significantly reduces the chance of dermatitis occurring in the wearer. Even with the addition of the two white metals, the finished alloy still has a slightly warm look, and so a rhodium plating is applied to brighten the alloy.

The problem with the plating is that it is, in itself, not particularly durable, and white gold rings and other items will require re-plating after several years, due to the rhodium wearing off.

However, despite this minor inconvenience, white gold has brought the “platinum look” to far more people than would otherwise have been possible with simply using platinum. White gold is beautiful with colorless diamonds, and also complements colored stones like rubies, emeralds and sapphires perfectly. Click here to compare white gold and platinum.

Rose Gold

Rose gold, originally known as “Russian gold” due to its popularity there in the early 19th century, and now commonly also referred to as pink or red gold, is another alloy, and has been increasing steadily in popularity over the last 20 years, even to the point of being simulated as a finish for smartphones.

Rose gold is an alloy of yellow gold, copper and silver, with the copper to silver ratio usually being the determining factor for how rose/pink/red the final color is. The yellow gold volume is usually fairly consistent at around 75% making rose gold, in effect, 18K gold. It also doesn’t bring any of the plating or skin irritation problems of white gold, but has greatly increased durability over yellow gold.

Rose gold is increasingly used for wedding rings, as it is just that bit different and is likely to draw admiring comments from all who see it. When used to set stones, rose gold is surprisingly versatile, but is best when set with colorless diamonds. The contrast between the white of the diamond and the relative boldness of the rose gold makes a breathtaking combination.

Like with many things, the color of the metal you choose for your ring will be decided by a combination of your personality and any jewelry you may already own.
