We love the simple geometric shape of the lattice ring. The center stone is an 18pt princess-cut diamond set with points facing top and bottom, like a diamond shape. This simple ring shines and because of the non traditional rotated setting of the princess cut, the stone stands out when stacked with other bands. Lattice can be generated from a basis for the vector space by forming all linear combinations with integer coefficients.
