Trillion Cut Studs Diamond + Aquamarine

Trillion-cut aquamarine framed in diamond.

The trillion is a triangular brilliant — three corners, and a cut designed to throw light outward from a shallow stone rather than down into it. It gives more visible surface per stone than a round, which is why a trillion stud wears larger than it measures.

Aquamarine's pale blue against white diamond keeps the pair cool and legible at a distance.
