Platinum Engagement Rings

Platinum Solitaire Rings — handmade in Spain since 1917

Discover the timeless elegance of platinum solitaires, a choice that transcends fashions and generations. At Nicols Joyeros, with four generations of experience since 1917, we craft each piece with the precision and care that only traditional craftsmanship can offer. Platinum, with its unique shine and exceptional resistance, becomes the perfect stage to enhance the natural beauty of each diamond.

Each platinum solitaire is a declaration of commitment and distinction. We select only natural diamonds, guaranteeing quality and authenticity in every gem. Our commitment is to offer pieces that endure over time, reflecting sincere emotions without artifice. Find in our collection the purity and strength that only platinum can bring to a classic and sophisticated design.

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, 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.
