Gold has fascinated the jewelry world for thousands of years. It’s glorious reputation is unparalleled, but with mounting demand for diversity and individuality, more colorful variations of gold, combined with innovative designs, are breaking ground in the trade.

Highly sought after for it’s durability and sentimental allure, gold is an integral part of the jewelry industry. The precious metal comes in three major colours used largely in jewelry manufacturing – yellow, white and rose gold.

Yellow gold’s illustrious deep hue, while often viewed as traditional, continues to dominate the jewelry market but interest in different coloured gold is on the rise.

According to the 2019 Retail Gold Insights report by the World Gold Council (WGC), yellow gold accounts for 57 per cent of jewelry purchases in the US compared to 31 per cent for white gold. In comparison, 25 per cent of consumers are buying rose gold jewellery pieces – up from 12 per cent in 2016.

Rose gold’s warm, blushing pink hue and on-trend appeal are mainly popular with Gen Z and younger millennials, according to WGC.

Jewelry manufacturers, designers and metals experts are answering modern buyers’ escalating demand for individuality and more stylish variations of traditional gold jewellery. Over the years, the market has seen an increased use of gold alloys in jewelry making to further inject diversity and innovation in the trade.

Colored Gold

Retailers and end-consumers alike place great importance on karat weight when purchasing gold jewelry but different colors of gold alloys can also be considered. Among the most common non-traditional gold colors used in jewelry production are green and red. Even rarer are pink, blue and purple gold.

The color of gold changes when other metals or alloys are added to it, providing the market with a variety of palettes. Dr. Ko Po Hung, head of sales for functional metals at precious metals expert Heraeus Ltd, explained that the coveted white hue is achieved by adding nickel or palladium to gold while coloured gold, which pertains mainly to yellow, green, pink/rose or red, is the result of changing the ratio of copper and silver content in the alloy.

More intricate colours such as purple or blue can be attained by mixing special elements that form intermetallic compounds with gold.

According to Ko, white gold has a solid following in the global jewellery industry but demand for coloured gold is steadily increasing, particularly in non-Western markets such as India and the Middle East, which have strong religious and cultural influences.

Buyers are also keen on purchasing trendier colours of gold that complement the colour of their skin.

A broad selection of red/pink gold has been making waves in the trade. According to Ko, red gold is relatively more difficult to produce, especially for 18-karat variants due to the intrinsic interaction between copper and gold that results in brittleness in the alloy. This problem arises when the alloy is improperly produced.

Heraeus sells red/pink gold alloy with a special ingredient aimed at tackling this problem, revealed the company official.

Some jewelry manufacturers produce purple or blue gold, but these alloys are quite fragile, which makes them almost impossible to use in traditional jewelry.

In 2015 however, a suite of diamond-studded, bi-coloured jewelry by Swiss jeweler Ludwig Muller sold for around US $4,500 at a Christie’s Jewels & Watches auction. The necklace is composed of curvilinear “blued” segments and panels, with diamond-set spacers.

Muller has reportedly developed and patented a blue gold alloy, but there is limited information on his supposed invention.

Ko said there is no shortage of market requests for fancier gold color, but these are not widely produced. As an alternative, different colors are achieved by surface treatment such as electroplating or other chemical or physical coating.

Jewelry designer Gnel Karapetyan of fine bridal jewelry expert Art Masters Jewelry and Caravaggio Jewelry brands said the company’s best sellers are black and violet gold jewelry, with the vivid, attractive colors continuously finding favour among online buyers.

Of around 7,000 pieces and color schemes in the jeweler’s product portfolio, about 20 per cent is black gold. Blue gold is visually engaging, thanks to it’s opulent color, but production is complicated.

Such requires advanced and more expensive electroplating methods, remarked Karapetyan. The company applies state-of-the-art Italian nanoceramic coatings over solid white gold through electroplating at high voltages to achieve intense gold colors and new comprehensive gold colors such fuchsia and cyan have been recently released to US, Canada and UK online shopping catalogs.

The resulting 14-karat gold rings are further adorned with colored gemstones such as alexandrite, sapphire, ruby, emerald, amethyst and topaz, to name a few. Black gold is attained with the use of ruthenium coating.“

The dramatic contrast of colored gold with color gemstones are reminiscent of the Renaissance Art color styles of Raphael and Caravaggio. We also use larger accent stones to really bring out the colors of jewelry pieces; to me it’s about an inspiration, an engagement; a study of color and #art,” noted Karapetyan.


Finding a more efficient way to use intermetallic compounds in jewelry production remains a challenge but there are alternative ways to present colored gold in jewelry pieces.

For instance, they can be facetted and used as embellishments or inlays in a jewelry piece or watch.

Other sturdier colored gold alloys also face some challenges. According to Ko, coloured jewelry pieces contain substantial amounts of silver or at times iridium – one of the six platinum group metals. The fluctuating price of such metals could affect market acceptance of these alloys.

Another issue is tarnishing of some complementary elements in the coloured gold, especially in low-karat items. Maintaining the bright and shiny colour of such metals also poses difficulty for manufacturers since electroplating is not as widely accepted.

As for Karapetyan, the challenge is coming up with unique jewelry design pieces for it’s increasingly style- and colour-savvy customers. The company’s main products are bridal jewelry pieces in contemporary designs, with a focus on design styles and color combination creatives.

With the market leaning more and more towards distinctiveness and self-expression, buyers are likely to demand for more innovative use of exceptional colored gemstones in their jewelry, he added.

Colored gold will be in the exclusive domain of the artistic world and mainly used in special pieces for exhibition in complimenting contrast to mainstream jewelry collections. Undoubtedly however, discerning consumers will continue to opt for more engaging colors and styles in their jewelry choices, continued Karapetyan.

Ko echoed this sentiment, adding that demand for exceptionality in the jewelry sector shows no signs of abating. “The use of colored gold is not entirely new, but its popularity relies heavily on jewelry designers – whether they can express coloured gold in a way that would be satisfactory to consumers,” he stated.

Precious metals suppliers assist jewelry designers and manufacturers in achieving their dream product or collection. Heraeus is in the process of finding ways to make it’s alloys more attractive to its clients, investment- and product-wise.

“Innovation is one of our core values. We continue to modify alloys to develop more user-friendly products as well as alloys with less expensive ingredients at a more competitive cost,” noted Ko.
