A Classic Expression of Everlasting Love
The Nikki solitaire engagement ring from Ralph Jacobs Jewellers embodies timeless elegance and heartfelt emotion. Designed for both first-time buyers and seasoned jewellery lovers, this ring promises to be a beautiful symbol of your unique journey together.
At its centre is a dazzling cushion-shaped stone, which you can personalise using our diamond ring builder. Choose from a Natural Diamond, Lab-Grown Diamond, Coloured Gemstone, or even your own cherished stone, all securely held by four delicate claws that showcase the gem’s brilliance.
The band is crafted from lustrous platinum and finished with a smooth, plain style that perfectly complements the solitaire setting, enhancing the focus on the stunning centre stone.
Expertly made in South Africa, this ring reflects exceptional craftsmanship and a commitment to ethical sourcing. Its durable design is created to withstand everyday wear while maintaining its elegant appeal for a lifetime.
With Ralph Jacobs Jewellers, you’re not just investing in a diamond engagement ring — you’re embracing a legacy of quality, trust, and personalised service that lasts for generations.
