AGI Design Collection
Engagement Rings
This collection offers timeless round, oval, cushion, and princess cuts, beautifully set in classic solitaires or radiant halo designs. It is created with Premium Moissanite, Forever One, and a range of coloured options in white, yellow, and rose gold.
Wedding Bands Jewellery
Mark your milestone with wedding bands that radiate meaning and beauty. We have sleek rope styles, classic eternity bands, and everything in between that await in yellow, white, and rose gold finishes. You can select lab-created diamonds, Moissanite, or minimalist metal bands to reflect your unique bond. Our vintage-inspired, baguette-cut, curved, and contoured designs suit both stackable looks and standalone elegance.
Earrings
Add a brilliant finishing touch with AGI Design's curated earrings collection. This lightweight, luminous, and ethically made handpicked selection includes classic round Moissanite studs, elegant dangles, and gemstone-accented designs—each crafted in 14K white or yellow gold. You’ll find lab-created diamonds, Forever One Moissanite, and vibrant stones like London Blue Topaz, all set to enhance your everyday style or special occasion look.

Your vision comes to life in lab-created diamonds or Moissanite, set in the metal of your choice.
