Nikki Platinum Solitaire Engagement Rings | Oval Shape
Elegant Simplicity: The Nikki Solitaire Engagement Ring
The Nikki solitaire engagement ring is a timeless expression of love, designed to capture the heart with its graceful and refined silhouette. This ring perfectly balances classic elegance with modern sophistication, making it a cherished choice for both first-time buyers and seasoned jewellery enthusiasts.
The centre stone features a stunning oval shape, available as a Natural Diamond, Lab-Grown Diamond, Coloured Gemstone, or your own stone through our diamond ring builder. Expertly held by four claws, this gem is showcased beautifully, reflecting light with exceptional brilliance.
Set on a plain platinum band, the design allows the oval stone to truly shine. The sleek band complements the solitaire style, offering durability and a comfortable fit for everyday wear.
Crafted with pride by South African artisans, this ring honours ethical sourcing and meticulous craftsmanship. Each piece is made to last, combining beauty with responsible creation for a ring you’ll treasure forever.
With Ralph Jacobs Jewellers, you receive not only a stunning diamond engagement ring but also a promise of quality, heritage, and the freedom to customise your ring to perfectly suit your unique love story.
