1 Ct Diamond Rings

1 ct Diamond Rings — handmade in Spain since 1917

Discover excellence in 1 ct diamond rings, an expression of elegance and commitment that Nicols Joyeros has perfected since 1917. Four generations of artisans have dedicated their passion and expertise to creating unique pieces in 18k gold and platinum, enhancing the natural beauty of GIA or IGI certified diamonds starting from 0.25 ct. Each ring is a testament to precision and authenticity, designed for those who value quality and legacy.

Choose from designs that combine tradition and modernity, crafted with meticulous detail to highlight the purity and unmatched brilliance of the 1 ct diamond. At Nicols Joyeros, each jewel is more than an accessory: it is a story of four generations reflected in every line and stone, offering pieces that transcend time and become symbols of unforgettable moments.

Each ring is designed and crafted in our own workshop in Madrid, where we also perform resizing, personalized engravings, and repairs to ensure a perfect fit and lasting beauty.

Financing options are available, along with 30-day no-commitment returns and insured shipping for your peace of mind.

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