18k Gold-Plated Sterling Silver

Our jewellery features genuine sterling silver coated with a layer of 18k gold, delivering the luxurious appearance of gold with the strength and affordability of sterling silver.

  • Luxurious Finish: The 18k gold plating provides a rich, warm hue that mimics the look of solid gold, offering elegance and sophistication without the high cost.
  • Durability: Sterling silver is a robust metal that, when plated with 18k gold, creates jewellery that is long-lasting and resistant to tarnish with proper care.
  • Affordability: By using 18k gold plating over sterling silver, we provide high-end design and quality while keeping the price accessible.

Cubic Zirconia

Cubic zirconia is a stunning gemstone that resembles a diamond, known for its exceptional sparkle and brilliance at a more accessible price.

  • Diamond-Like Sparkle: Cubic zirconia is renowned for its ability to emulate the brilliance and fire of a diamond, offering a similar dazzling effect.
  • Versatility: Available in a variety of cuts, colours, and sizes, cubic zirconia allows us to create versatile designs to suit every style.
  • Eco-Friendly: As a lab-created stone, cubic zirconia is produced with minimal environmental impact and is conflict-free.

Synthetic Corundum

Synthetic corundum, including lab-created sapphires and rubies, shares the same chemical composition and physical properties as natural corundum.

  • Vivid Colour: Synthetic corundum is celebrated for its vibrant, intense colours, from deep blues to rich reds, rivalling the hues of natural gemstones.
  • Hardness and Durability: With a hardness rating of 9 on the Mohs scale, synthetic corundum is highly durable and suitable for everyday wear.
  • Ethical Sourcing: Lab-created synthetic corundum eliminates the ethical concerns associated with mining, offering an environmentally responsible alternative.
