Green Engagement Rings

Green Engagement Rings — handmade in Spain since 1917

At Nicols Joyeros, with four generations of experience since 1917, we create emerald engagement rings that transcend time. Each piece is handcrafted in 18k gold or platinum, enhancing the unique beauty of carefully selected natural emeralds to offer exceptional brilliance and color.

Discover the elegance and symbolism that a natural emerald brings to your engagement ring. Our commitment is to offer authentic jewelry, with quality gems and settings designed to last a lifetime, reflecting the story and love you want to celebrate.

We work exclusively with 18k gold (white, yellow, or rose), platinum, and natural diamonds certified by GIA or IGI. Each ring is designed and crafted in our own workshop in Madrid, where we also perform resizing, personalised 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.
