Most listings use simulated cubic zirconia; at least one listing features moissanite.
The listings include a variety of cuts and shapes, such as round, princess (square/princess), emerald (emerald cut), cushion, and square styles.
Reported product diameters range from about 1 mm up to 21.4 mm. Band widths for anniversary or wedding bands are reported at roughly 1.4 mm up to about 5 mm.
Clean rings with appropriate jewelry cleaner or by spot/wipe cleaning. Remove rings for harsh chemicals or swimming, and store them in a soft pouch when not in use.
Reported grades vary: some cubic zirconia are listed as AAAA, others as AAA or 8A; one listing cites hearts‑and‑arrows AAAA quality. Moissanite listings reference separate quality metrics for that gem.
