The 18K gold guide
Why Lumiere uses solid 18K gold for fine jewelry designed to be worn every day.
Solid 18K gold, never plated
Lumiere jewelry is crafted in solid 18K gold: 75% pure gold alloyed for strength, durability, and the precise colour of each piece. We do not use gold plating for fine jewelry styles intended for long-term wear.
Yellow, white and rose gold
Yellow gold has a classic warmth, rose gold carries a softer blush tone, and white gold offers a cool, bright setting for diamonds. White gold may need occasional rhodium refreshment depending on wear.
Hallmarking and comfort
Each piece is finished to a fine-jewelry standard and designed for comfort against the skin. If you have metal sensitivities, contact our concierge before ordering so we can advise on the best option.
Care
Clean 18K gold with warm water, mild soap, and a soft brush. Store pieces separately, avoid chlorine and harsh chemicals, and book a professional check if a setting feels loose.
