Astra’s Prism | 3CT Oval Moissanite Halo Engagement Ring

Design overview

Astra’s Prism is an oval moissanite halo engagement ring built around a 3CT center outline. The elongated oval shape gives the ring a softer, balanced profile than a step-cut rectangle, while the surrounding halo adds a defined border around the center. The live selector separates two stone labels—High Class Moissanite and Lab-Grown Moissanite—so the selected label applies to the configuration chosen rather than combining both in one ring. Metal choices include yellow, white or rose gold plated 925 sterling silver, 10K, 14K or 18K yellow, white or rose gold, and 950 platinum. These are separate finish options for the same oval halo design. Across the 26 documented variants, the visual identity stays consistent: an oval 3CT focal stone framed by a halo, with the selected stone label and metal finish determining the configuration shown.
