Diamond trilogy rings have always been an all-time favorite. But since Prince Harry gave a three-stone diamond ring to Meghan Markle, these trilogy rings are more popular than ever. We at Coster thought: what could be more Royal than a Princess Trilogy? That’s why we made a princess cut diamond trilogy ring.
Instead of three stones, however, this ring contains six diamonds. Instead of one large stone in the middle, we used a cluster of four princess cut diamonds. This way it looks like one big diamond. In total, this princess cut diamond trilogy ring has six top wesselton diamonds with a VS-clarity. The diamonds have a combined weight of 0.93 carat.

An oval cut diamond ring is a perfectly viable option as a solitaire engagement ring. Very often, the oval looks a bit larger than a brilliant cut of the same weight.
