Elegant Simplicity with a Modern Twist
The Nikki solitaire engagement ring from Ralph Jacobs Jewellers is a timeless expression of love and commitment. Designed to resonate with both first-time buyers and seasoned jewellery enthusiasts, this ring combines classic elegance with contemporary refinement.
At its centre is a striking princess-cut stone, available as a Natural Diamond, Lab-Grown Diamond, Coloured Gemstone, or your own stone via our diamond ring builder. Securely held by four claws, the stone’s sharp facets catch the light brilliantly, making it the perfect symbol for a lifelong promise.
The ring features a plain band crafted from lustrous platinum, highlighting the solitaire design’s clean lines and enhancing the diamond’s natural sparkle.
Expertly made by South African artisans, the Nikki ring reflects our commitment to ethical sourcing and meticulous craftsmanship. Its durable design ensures it can be worn daily, carrying your story with grace and strength.
Choosing Ralph Jacobs Jewellers means choosing a diamond engagement ring crafted with integrity, quality, and a legacy that endures through generations.
