Rings in 18K gold

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

The difference lies in the pure gold content:

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

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

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

Yes, 18K gold offers an excellent balance between purity and durability. The 25% alloy of complementary metals reinforces the pure gold, which would otherwise be too soft on its own. An 18K gold ring can be worn every day without risk of rapid wear. The natural micro-scratches that develop over time create an elegant patina. Professional polishing can restore the original brilliance.

18K gold is one of the simplest metals to care for:

• Clean with a soft cloth and warm soapy water
• Dry gently
• Remove your ring during sport and manual work
• Avoid contact with chlorine and chemical products

Gold does not tarnish or oxidise. For white gold, rhodium plating may be required every 2 to 3 years to maintain its bright white appearance. Mayuri offers this service.

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

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

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

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

18K gold holds an intrinsic value linked to the gold price, which tends to appreciate over the long term. A solid gold ring set with natural precious stones can retain and increase its value over the years. It is a purchase that brings joy and represents a sound investment, a piece of jewellery to pass down through generations. The AAA-quality stones used by Mayuri further strengthen this value.

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

Yes, Mayuri is committed to responsible fine jewellery. More than 80% of our metals are recycled, and our gold is fully traceable, sourced through ethical supply chains. We work with artisan workshops and those certified by the RJC (Responsible Jewellery Council). Our precious stones are natural, with guaranteed traceability. Choosing 18K gold from Mayuri is a choice of both quality and conscience.

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

Each stone and metal pairing has its own character:

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

Mayuri can source rare stones upon request for a truly one-of-a-kind creation.
