Product Highlights
About the Product

Three stone rings always feel a little more considered, and the Lab Grown Columbian Emerald and Lab Grown Diamond Trilogy Ring gets the proportions exactly right. At the centre sits an octagon cut lab grown Columbian emerald in a rich, saturated green that immediately draws the eye. On either side, trapezoid cut lab grown diamonds add clean geometric lines that frame the emerald beautifully and give the ring a strong architectural feel. The combination of vivid green and bright diamond accents creates a look that feels polished, confident, and surprisingly versatile. It is the kind of ring that works for milestone birthdays, anniversaries, evening events, and occasions when you want your jewellery to feel a little more intentional. If you love gemstone rings with a structured silhouette and a strong colour story, this is an easy one to keep reaching for. It works beautifully as an anniversary ring or a statement ring that still feels wearable beyond special occasions.

  • Octagon emerald creates a rich, eye catching centrepiece.
  • Trapezoid diamonds add clean structure and balance.
  • Trilogy design gives the ring a strong, polished presence.
  • Perfect for anniversaries, celebrations, and evening wear.
