Princess Cut Lab Diamond Ring FAQs

What does a princess engagement ring mean?

It’s an engagement ring that features a princess-cut diamond as the center stone. This cut is characterized by a square or rectangular shape with pointed corners. Additionally, choosing a lab-grown princess-cut diamond ring often reflects a preference for a modern and elegant look.

Do princess-cut diamonds look bigger?

Princess-cut diamonds may appear slightly larger when compared to other cuts, such as the round cut. The distinct square or rectangular shape of this cut can create the illusion of greater surface area, and this is what makes princess-cut lab diamond rings seem larger.

How common are lab diamond engagement rings?

More and more people now opt for ethical and sustainable choices for their jewelry. As a result, lab-grown diamond engagement rings have become quite common in recent years. People are drawn to lab-diamonds due to their identical physical and chemical properties to mined diamonds and the fact that they often come at a more affordable price point.
