About the Product

Make your mark with The Guardian Shield ring, where a brilliant lab grown diamond meets a bold shield-inspired form for a powerful, polished statement. The polished surface creates a smooth, high-shine backdrop, allowing the central stone to stand out with crisp sparkle and strong visual impact. Crafted in 18K vermeil yellow gold plating over 925 sterling silver, the ring carries a rich golden lustre that enhances its sculptural form while maintaining a substantial feel on the hand. The broad shoulders flow seamlessly into the shield face, giving the design a confident profile, while the detailed openwork beneath adds a considered finishing touch. Striking yet wearable, the ring brings together modern symbolism, radiant sparkle and polished metalwork in a statement piece with unmistakable presence. A beautiful way to celebrate anniversaries and engagements, this design is a timeless symbol of commitment that will be worn and cherished every day.
