Solitaire Engagement Rings

Solitaire Rings — handmade in Spain since 1917

Discover the essence of eternal commitment with our Solitaire Rings, an iconic piece symbolizing love and dedication. Since 1917, Nicols Joyeros has perfected the art of creating unique jewelry, passing down the mastery of four generations in each ring. Each solitaire is crafted in 18k gold or platinum, carefully selecting natural diamonds that guarantee exceptional brilliance and purity.

The design of our rings focuses on highlighting the beauty of the diamond, always with a handcrafted and authentic approach. Choose from a variety of styles that combine tradition and modernity, ensuring each piece is as unique as the story it represents. At Nicols Joyeros, every solitaire ring is more than a jewel; it is a legacy that endures over time.

Each ring is designed and crafted in our own workshop in Madrid, where we also perform resizing, personalized engravings, and repairs.

Financing options are available, along with 30-day no-commitment returns and insured shipping.

Book your online consultation with a specialist to design your custom ring; visits to our boutiques in Madrid and Valencia are also available.
