Solitaire Diamond Necklace

At Olivier, we don’t settle for the industry standard; we set a higher one. While 14k gold (only 58.3% pure) is the standard in North America, every piece in our collection is crafted in 18k solid gold (75% pure).

Why 18k?

• Superior Color: A deeper, more authentic gold tone that 14k and 10k cannot replicate.
• Heirloom Purity: Marked with the "750" hallmark, signifying its value and authenticity in every corner of the world.
• Sustainably Sourced: Composed of 75% pure recycled gold, ensuring your investment is as ethical as it is beautiful.
• Lifetime Wear: Naturally hypoallergenic and tarnish-free. Unlike vermeil or plated jewelry, our 18k gold will retain its natural gold radiance and value for generations.

Each piece arrives with a Certificate of Authenticity—your permanent record of 18k purity and quality.

We are dedicated to ensuring ethical practices and sustainability is key:

• our manufacturers are proud members of the Responsible Jewelry Council;
• our diamonds are natural, ethically sourced, conflict-free and adhere to the Kimberly Process.

All our products are made in Italy by skilled, professional goldsmiths.

We offer complimentary shipping on all U.S. orders. Once your heirloom is securely dispatched, you will receive a tracking number to monitor your delivery.

We offer a 30-day return window for all unworn articles in their original packaging. Simply contact our support team to initiate a secure return or exchange.

18K solid gold is designed to last a lifetime. Unlike plated or vermeil jewelry, your Olivier pieces will never tarnish or lose their color.

To maintain its luster: Simply polish with a soft lint-free cloth. For a deeper clean, use mild soap and warm water. Because 18K gold is 75% pure, it is naturally resistant to the elements, allowing you to wear your investment daily with total confidence
