Elegant Simplicity in Every Detail
The Nikki solitaire engagement ring by Ralph Jacobs Jewellers is a timeless symbol of love and commitment. Crafted with care to appeal to both first-time buyers and seasoned jewellery lovers, this ring embodies understated elegance and lasting beauty.
At its heart lies a stunning cushion-shaped centre stone, which can be chosen as a Natural Diamond, Lab-Grown Diamond, Coloured Gemstone, or your own precious stone via our diamond ring builder. The four claw setting beautifully showcases the stone’s brilliance, ensuring it takes centre stage.
The band is designed in a classic plain style, crafted from lustrous 18k white gold that complements the diamond engagement ring with a modern, refined touch.
Proudly made in South Africa, this piece highlights exceptional craftsmanship and ethical sourcing. Designed for everyday wear, the Nikki ring offers durability and comfort while honouring the legacy of responsible jewellery making.
