Wedding ring 18k gold

A wedding ring is a lasting expression of commitment—something chosen with care, worn with pride, and treasured for a lifetime. Wedding rings 18K gold combine timeless elegance with everyday strength, making them an ideal choice for couples who value both beauty and durability. At Royal Coster Diamonds, we craft each ring with precision, tradition, and personal attention. 

The value of 18K gold

18-karat gold is composed of 75% pure gold and 25% alloyed metals, resulting in a material that is rich in color and resilient in wear. Whether you choose yellow, white, or rose gold, each 18K gold wedding ring offers a different aesthetic, from traditional to modern and everything in between. 

Yellow gold emits warmth and heritage, white gold is known for its sleek and refined finish, and rose gold brings a romantic, vintage feel. Each piece is created in-house by expert goldsmiths who bring craftsmanship and care into every design. 

For every couple

Our collection includes wedding rings for all styles and identities. 

We offer men’s wedding rings 18K gold that emphasize durability, balance, and individuality. With a wide selection of widths, surface textures, and shapes, every man can find a ring that feels right.
