18k gold rings

18K gold, also marked as 750, is an alloy composed of 75% pure gold and 25% complementary metals (silver, copper, palladium depending on the colour). It is the international standard for fine jewellery. The 750 hallmark guarantees this composition. It offers the perfect balance of purity, durability and beauty.

The difference lies in the pure gold content:

• 18K gold (750/1000): 75% pure gold, rich and luminous colour, fine jewellery standard
• 14K gold (585/1000): 58.5% gold, common in the USA, less luminous
• 9K gold (375/1000): 37.5% gold, more affordable but paler colour

At Mayuri, we work exclusively with 18K gold to guarantee the highest quality and incomparable colour.

Authentic 18K gold jewellery bears an official hallmark: the number 750 (indicating 750/1000 pure gold). This hallmark is stamped by an approved assay office. At Mayuri, each ring comes with a certificate of authenticity confirming its composition. Be wary of jewellery without a hallmark or sold at unusually low prices.

Yes, 18K gold offers an excellent balance between purity and strength. The 25% alloy of complementary metals reinforces the pure gold, which is too soft on its own. An 18K gold ring can be worn daily without fear of rapid wear. The natural micro-scratches that appear over time create an elegant patina. Professional polishing can restore the original lustre.

18K gold is one of the simplest metals to maintain:

• Clean with a soft cloth and warm soapy water
• Dry gently
• Remove your ring for sports and manual work
• Avoid contact with chlorine and chemicals

Gold does not tarnish or oxidise. For white gold, re-plating may be needed every 2 to 3 years to maintain the silvery shine. Mayuri offers this service.

The colour of 18K gold depends on the alloy metals:

• Yellow gold: alloy of gold, silver and copper in equal parts, classic natural colour
• White gold: alloy of gold and palladium (or nickel), coated with bright white rhodium plating
• Rose gold: alloy of gold with a higher proportion of copper, soft and romantic hue

All three colours contain exactly 75% pure gold and have the same value.

18K gold is very well tolerated and rarely causes allergies. Its high pure gold content (75%) minimises contact with potentially sensitising alloy metals. It is a much safer choice than 9K gold (37.5% gold) for reactive skin. If you have a known nickel sensitivity, choose yellow gold or rose gold, which contain none.

18K gold has intrinsic value linked to the gold price, which tends to appreciate over time. Solid gold jewellery set with natural gemstones retains and can increase its value over the years. It is both a pleasure purchase and a heritage choice, a piece to pass down through generations. The AAA quality of Mayuri gemstones reinforces this value.

Rhodium plating is a surface treatment applied to white gold. Natural white gold has a slightly grey or yellowish tint. Rhodium, a precious metal from the platinum family, is deposited in a thin layer to give the characteristic bright white shine. This treatment wears naturally over time (2 to 3 years on average) and can easily be reapplied. Yellow gold and rose gold do not require rhodium plating.

Yes, Mayuri is committed to responsible jewellery. Over 80% of our metals are recycled and our gold is traceable, sourced from ethical suppliers. We work with small-scale workshops or those certified by the RJC (Responsible Jewellery Council). Our gemstones are natural with guaranteed traceability. Choosing Mayuri 18K gold is a choice of quality and conscience.

Ring stacking is a strong trend in fine jewellery. 18K gold is perfect for stacking: its durability allows you to wear multiple rings side by side without fear of wear. Mix gold colours (yellow and rose, white and yellow) and gemstones for a personal look. Vary the widths and designs to create a unique ensemble. Our rings are specifically designed to be worn stacked.

Each stone and metal combination has its own character:

• Diamond: the universal choice, stunning on all three gold colours
• Sapphire with white gold: cool and aristocratic pairing
• Ruby with yellow gold: regal and warm duo
• Emerald with yellow or rose gold: vibrant and refined contrast
• Black diamond with rose gold: modern and distinctive

Mayuri can source rare gemstones on request for a truly unique creation.
