Ring Details
Understated Elegance, Thoughtfully Designed
The Nikki engagement ring is a refined take on a timeless classic. With its solitaire style and graceful details, it’s a symbol of commitment and lasting beauty. Whether you’re beginning a new chapter or celebrating a lifelong bond, the Nikki ring offers a meaningful way to mark the moment — elegant enough for the connoisseur, and accessible for the first-time diamond buyer.
At the heart of the Nikki ring is a cushion-cut centre stone, secured with four claws that highlight its soft edges and romantic brilliance. With our diamond ring builder, you can customise the stone to suit your preference — from a sparkling Natural Diamond or Lab-Grown Diamond to a Coloured Gemstone or even a stone you supply yourself. The cushion shape’s unique blend of round and square qualities gives this engagement ring a warm, vintage-inspired glow.
The 9k white gold band complements the centre stone with a cool, contemporary finish. Delicately set accent stones — available in Natural Diamonds, Lab-Grown Diamonds, or Moissanite — add just the right amount of shimmer, enhancing the solitaire design without overwhelming it. This subtle sparkle adds depth and charm while allowing the centre stone to shine as the focal point.
Each Nikki ring is handcrafted in South Africa by skilled artisans who bring decades of expertise to every detail. We are committed to ethical sourcing, ensuring that every diamond and gemstone we use meets responsible standards. Designed for daily wear, this engagement ring offers both enduring style and lasting comfort, so you can wear it with confidence for years to come.
With Ralph Jacobs Jewellers, you’re choosing more than a ring — you’re choosing legacy, integrity, and South African craftsmanship. The Nikki engagement ring carries our promise of quality and care, designed to be treasured today and for generations to come.
