Trillion Halo-Style Birthstone Ring

Few shapes turn heads like a trillion, its three brilliant sides throwing light in a way round stones simply cannot.

A close diamond halo tucks around the triangle and keeps the profile low, so this statement wears comfortably day to night.

It is the gift for the person who never wanted the ordinary birthstone ring.

We set trillions only in the birthstones we can source cut to an exact trillion, so a handful of months lead this style, each one honest and in stock.

Your gemstone. Genuine natural Amethyst and Citrine. Lab-created Alexandrite, Emerald, and Ruby, grown to be optically and physically identical to mined stones. Each center is precision-calibrated to an exact millimeter size and hand-set at our bench. Accent diamonds, where present, are natural and conflict-free.
