Ring Details
Refined Romance in Every Detail
The Nikki engagement ring is a graceful blend of timeless charm and modern elegance. Designed for those who appreciate both classic beauty and personal expression, it’s the kind of ring that captures a love story in a single glance. Whether you’re planning a surprise proposal or choosing it together, the Nikki is made to mark one of life’s most meaningful moments with poise and sentiment.
At the centre of the Nikki lies a brilliant round diamond, secured by four delicate claws that allow the stone’s sparkle to shine from every angle. You have the option to customise the centre stone through our diamond ring builder — selecting a natural diamond, a lab-grown diamond, a vivid coloured gemstone, or even a stone of your own. This flexibility ensures that your engagement ring reflects not only your style, but your values too.
Crafted in romantic 14k rose gold, the band features a refined row of accent stones for added brilliance. Whether you choose natural diamonds, lab-grown diamonds, moissanite, or prefer a more minimal look without accent stones, the Nikki offers understated luxury and a perfect balance between centrepiece and setting.
Each Nikki ring is handcrafted in South Africa by master jewellers who bring years of skill and passion to every piece. With ethically sourced materials and a focus on everyday comfort, this engagement ring is designed to be worn and loved for years to come. Durable, thoughtfully designed, and always elegant — it's made for life's most precious moments.
When you choose Ralph Jacobs Jewellers, you choose a legacy of trust, quality, and South African artistry. The Nikki is more than just a diamond ring — it’s a promise, carefully crafted to honour your love story today and for generations to come.
