AAA Grade CZ:
AAA Grade CZ is a manmade stone, in which its refractive index, dispersion and hardness is extremely close to those of a natural diamond. It also creates more flashes of color, giving it a fiery and brilliant appearance.
Imitation Rhodium uses a similar-looking material to substitute for rhodium. It makes the jewelry more affordable, but at the same time keeps the same appearance and quality as a rhodium coating.
