Engagement Rings

Engagement Rings — handmade in Spain since 1917

Since 1917, Nicols Joyeros has been synonymous with commitment and excellence in creating rings that symbolize eternal love. Each piece is the result of four generations of artisanal mastery, where 18k gold and platinum combine with natural diamonds selected to reflect the purity and strength of a unique bond. Here, the engagement ring is not just jewelry; it is a tangible promise, designed to accompany every love story with authenticity and elegance.

In our collection, you will discover rings that balance tradition and modernity, focusing on quality and detail that only a workshop with over a century of experience can offer. Choose from yellow, white, or rose gold, and natural diamonds with GIA or IGI certification starting at 0.25 ct, to make your engagement an unforgettable and genuine moment. At Nicols Joyeros, each ring is an artisanal work that celebrates the beginning of a shared journey.

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.
