Engagement rings: white gold with character, rhodium plating to make the diamond shine even more.<\/h2>\n

Why white gold reigns in engagement rings<\/h2>\n

White gold rings have been considered a symbol of luxury for decades. Engagement rings feature many different styles and traditions to choose from. They provide the diamond with an icy tint, allowing the stone to shine without the yellow hue that is often noticed in a traditional 585 yellow or rose gold ring. White gold engagement rings are renowned for their high quality, durability and meticulous craftsmanship. However, “white gold” is not homogeneous: we are talking about two different versions of it \u2013 naturally warm and rhodium-plated icy.<\/p>\n

What is rhodium?<\/h2>\n

Rhodium \u2013 marked with the symbol Rh in the periodic table of elements, belongs to the platinum group metals. It is a silvery-white, exceptionally hard and corrosion-resistant metal, whose Mohs hardness exceeds that of gold and even platinum. Due to its exceptional brilliance and reflectivity, jewellers worldwide use rhodium to plate white gold, so that it acquires a brightly icy tone and additional protection against scratches.<\/p>\n

Rhodium metal: unique physical and chemical properties<\/h2>\n

Rhodium metal features a record-low electrical resistance, incredible reflectivity (reflects \u2248 80% of visible light) and a high melting point (1964 \u00b0C). Such properties are not only useful in jewellery, but also make rhodium irreplaceable in car catalytic converters, electrical contacts and optical devices.<\/p>\n

History of rhodium discovery<\/h2>\n

Rhodium was discovered in 1803 by the British chemist William Hyde Wollaston, while investigating platinum ore. He named the new element rhodium \u2013 from the Greek “rhodon” (rose), because certain of its compounds are coloured pink.<\/p>\n

Rhodium price today<\/h2>\n

On 11 July 2025, the global rhodium spot price reached about 5,700 USD per troy ounce (\u2248 183 USD\/g). This is several times more than the price of platinum or gold, so it is no wonder that plating rings with rhodium is the most expensive jewellery finishing procedure.<\/p>\n

Why is the price of rhodium so fluctuating?<\/h2>\n

The price of rhodium depends on extremely limited supply (over 80% of supply comes from South Africa) and high demand in the automotive industry. When car manufacturers increase orders for catalytic converters, the rhodium price shoots up, and when production decreases, it falls. Even a minor supply disruption can cause a double-digit percentage price jump.<\/p>\n

Rhodium use in the world \u2013 from catalytic converters to jewellery<\/h2>\n

The largest consumer of rhodium is the automotive industry, where rhodium metal neutralises nitrogen oxides in catalytic converters. Electronic devices rely on rhodium’s conductivity, and the chemical industry on its catalytic properties. In jewellery, rhodium is desired for its white, mirror-like layer, which gives jewellery pieces a long-lasting brilliance.<\/p>\n

Natural white gold: warm champagne brilliance<\/h2>\n

Natural white gold is a gold alloy with palladium, silver or nickel. Even with whitening metals, this alloy retains a subtle, champagne hue. Such a colour beautifully highlights warm-toned gemstones (morganites, champagne diamonds) and looks more organic on a warm skin tone. Important: natural white gold is not rhodium-plated, so its colour will remain constant and will not require renewing.<\/p>\n

\"Classic<\/p>\n

Besides natural white gold, there is also rose gold and yellow gold, which features a warm, pinkish hue and is popular among those seeking an exclusive ring colour.<\/p>\n

Icy white gold: rhodium-plated ideal standard of cold white colour<\/h2>\n

When a completely neutral, “icy” white colour is desired, the surface of the natural alloy is plated with a thin (0.2\u20130.5 \u00b5m) layer of rhodium. This coating removes the warm yellowness, so the diamond looks snow-white. Rhodium-plated rings are particularly popular among those who desire the cleanest, highest-class appearance.<\/p>\n

Rhodium plating of engagement rings<\/h2>\n

In the category of engagement rings, rhodium plating is like a “gold standard”. For example, a white gold ring with a diamond is often rhodium-plated so that the stone shines even more. The ring is first polished, cleaned in an ultrasonic bath, and then electrochemically immersed in a rhodium solution. The process takes just a few minutes, but rhodium metal incomparably improves the final brilliance and resistance.<\/p>\n

Rhodium plating of wedding rings<\/h2>\n

Wedding rings are often worn daily, so the rhodium coating on them performs two functions: it protects against scratches and provides a uniform tone when one partner chooses a platinum ring and the other a white gold ring. The seamless colour coordinates beautifully in couple photographs and symbolises unity.<\/p>\n

The most popular proportions of white gold alloys<\/h2>\n

In Europe, 585 (14K) and 750 (18K) white gold alloys are the most commonly found. The 585 level is chosen by very practical buyers: it is harder, more resistant to scratching. At the 750 level there is more gold, so the tone is warmer, and the rhodium coating is even more important for achieving the perfect white colour.<\/p>\n

Engagement ring design: from classic to modern<\/h2>\n

Engagement ring design is the first step in creating an exclusive symbol of love that will accompany you throughout your life. From timeless classics to bold modern solutions, rings can reflect both your personality and the uniqueness of the relationship. Rings with a diamond are a symbol of eternal elegance and luxury that never goes out of fashion. However, if you desire exclusivity, it is worth choosing a ring with a sapphire, emerald or ruby \u2013 these coloured gemstones give the ring colours and individuality. The engagement ring design can be minimalist, subtle, or expressive, with intricate patterns or unexpected accents. The most important thing is to choose a ring that will reflect your style and become a true symbol of your love.<\/p>\n

Engagement ring types: discover your style<\/h2>\n

When choosing an engagement ring, it is worth knowing that there is more than one ring type that can reflect your personality and love story. A classic engagement ring is one of the most popular choices, symbolising eternal love and a promise. If you want exclusivity, you can choose a modern ring with non-traditional shapes or coloured stones. Halo style rings, where the main stone is surrounded by smaller gemstones, provide additional brilliance and luxury. Three-stone rings symbolise the past, present and future, and eternity rings \u2013 endless love. Every engagement ring type can be adapted to your style, so the most important thing is to choose what is closest to your heart.<\/p>\n

Gemstones: brilliance that complements white gold<\/h2>\n

Gemstones are a detail that gives an engagement ring a special charm and exclusivity. A diamond is undoubtedly the most popular choice, which symbolises eternal love and is highly valued for its brilliance and durability. However, if you want to give the ring more colours or personality, you can choose a sapphire, emerald, ruby or another gemstone that will reflect your style and love symbolism. Gemstones coordinate perfectly with white gold, rose gold or even silver rings, giving them a unique brilliance and character. The most important thing is to choose a stone that is meaningful to you and will become part of your love story.<\/p>\n

Shape and size: how to choose the perfect ring<\/h2>\n

The perfect engagement ring starts with choosing the right shape and size. The ring shape can be Round \u2013 for lovers of classic style, Oval \u2013 for those seeking subtle exclusivity, square or even asymmetrical \u2013 for the bold and modern. Size is also important: the ring must be comfortable, match your finger size and the rhythm of daily life. Smaller, subtle rings will suit fans of minimalist style, while larger, expressive ones \u2013 for those who want the ring to become the main accent. The engagement ring shape and size can be coordinated with various gemstones, which will further highlight your chosen style and give the ring a unique brilliance.<\/p>\n

How long does rhodium plating last?<\/h2>\n

The rhodium layer lasts for 12\u201336 months, depending on wear intensity, skin pH and cosmetic products. On an engagement ring, which is constantly touched by hand soap or sanitiser, the plating can begin to wear off already after a year. Fortunately, it is possible to rhodium-plate a ring at any professional jeweller.<\/p>\n

Care tips for rhodium-plated rings<\/h2>\n

Take off the ring when doing sports, swimming in a pool with chlorine or working in the garden \u2013 chemicals and metal particles accelerate the wear of the coating. Clean with warm soapy water and a soft brush, avoiding ultrasonic baths at home.<\/p>\n
