Diamond Promise Rings

Promise Diamond Rings — handmade in Spain since 1917

Discover the essence of eternal commitment with our Diamond Promise Rings, a tradition that Nicols Joyeros has cultivated since 1917. Each piece reflects the mastery of four generations of artisans who work exclusively with 18k gold and platinum, guaranteeing a jewel that lasts as long as the feeling it represents. The natural diamonds, rigorously selected, provide authentic brilliance and unsurpassed quality, ideal for sealing promises that transcend time.

In our collection, each ring is more than a symbol: it is a story of love and trust, designed for those who value authenticity and excellence. Choose from styles that combine tradition and modernity, with GIA or IGI certified diamonds starting from 0.25 ct, ensuring transparency and value. Make it unique, choose a ring that speaks of your commitment with the strength and elegance that only Nicols Joyeros can offer.

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.
