Timeless Elegance: The Nikki Solitaire Engagement Ring
The Nikki solitaire engagement ring embodies simplicity and sophistication, making it an exquisite choice for anyone looking to celebrate love with a meaningful and elegant piece. Its classic design ensures it remains a cherished symbol for years to come.
At its heart lies a stunning round centre stone, which you can personalise through our diamond ring builder. Choose from a Natural Diamond, Lab-Grown Diamond, Coloured Gemstone, or even your own precious stone. The four claws securely hold the stone, allowing maximum brilliance and sparkle to shine through.
The plain band is crafted from 18k white gold, offering a sleek and timeless backdrop that enhances the stone’s beauty while providing everyday comfort and durability. This minimalistic band style is perfect for those who appreciate refined elegance.
Meticulously handcrafted by skilled South African artisans, this engagement ring reflects Ralph Jacobs Jewellers’ commitment to ethical sourcing and superb craftsmanship. Designed for daily wear, the Nikki ring is as practical as it is beautiful.
With Ralph Jacobs Jewellers, you receive not just a ring but a promise of quality, integrity, and the flexibility to customise your Nikki engagement ring to perfectly reflect your unique story and style.

How to measure your ring size
Each ring is crafted to order, tailored to your chosen diamond and ring size. For this reason, please confirm your ring size before you order: resizing later means cutting and soldering the band.
