Ring Details
Effortless Elegance with a Golden Glow
The Nikki engagement ring is a celebration of timeless beauty and heartfelt intention. Designed to mark life’s most meaningful moments, this classic solitaire is perfect for those seeking something refined yet personal. Whether it’s your first diamond purchase or a treasured addition to your jewellery collection, the Nikki ring brings together emotion, elegance, and enduring style.
At the heart of the design lies a cushion-cut centre stone, gently held in a four-claw setting that allows light to flow through its soft, rounded edges. With our bespoke diamond ring builder, you can customise the ring with a Natural Diamond, Lab-Grown Diamond, Coloured Gemstone, or even a stone of your own. The cushion cut is beloved for its romantic shape and vintage charm — ideal for a truly unforgettable engagement ring.
Crafted in rich 18k yellow gold, the band offers a warm, classic contrast to the brilliance of the centre stone. A fine row of accent stones — your choice of Natural Diamonds, Lab-Grown Diamonds, or Moissanite — adds a subtle shimmer, enhancing the overall design without overwhelming its elegant simplicity. This thoughtful detail ensures the Nikki ring remains timeless while offering a touch of modern refinement.
Handmade in South Africa by skilled local artisans, every Nikki ring embodies Ralph Jacobs’ commitment to expert craftsmanship. We take pride in using ethically sourced diamonds and gemstones, giving you peace of mind with every purchase. Built for comfort and made to last, this ring is designed for everyday wear — from the moment you say “yes” to every day thereafter.
When you choose Ralph Jacobs Jewellers, you’re choosing a legacy of quality, trust, and authentic South African artistry. The Nikki engagement ring is more than a symbol of love — it’s a piece of your story, crafted to be treasured for generations to come.
