Choosing a Lab Grown Ruby Engagement Ring

Ruby brings a rich red centre to an engagement ring, ranging in appearance from lively pinkish red to a deeper, more saturated colour. Lab grown ruby is corundum, the same gemstone species as natural ruby, and gives you a striking alternative to a white diamond.

Compare the red in real lighting

Look at photographs and, where possible, the gemstone itself under natural and indoor light. The apparent colour can change with light temperature and with the surrounding metal. Yellow gold creates a warm combination, while platinum or white gold emphasises contrast. An oval ruby can feel classic; a cushion or geometric cut gives a different silhouette.

A diamond halo adds brightness around the red stone, while a simple setting puts the ruby colour centre stage. Think about the height and edge protection of the setting for daily wear, and confirm how a future wedding band will sit with it. Explore more options in our lab grown gemstone engagement rings.
