Why Choose a RZ® SIMULANT DIAMOND?

BEAUTY

The RZ® SIMULANT DIAMOND averages a D in color, FL to IF in clarity and is cut using the GIA grade an excellent cut.

As a result, it is the most beautiful, realistic, natural looking diamond simulant ever created and compliments the finest earth-mined diamond jewelry superbly.

CREATION

The RZ® SIMULANT DIAMOND is created by placing a perfectly cut crystal core or substrate into a chamber of intense heat and pressure and infusing lab-created diamond crystals, or bonding them at a molecular level, into the outer layers of the crystal core. These Lab created diamond crystals stack up on the core and realign with each other. The finished product is a diamond infused simulant that has a non precious crystal core and a solid outer layer of lab-created diamond that will never wear off or detach from the core.

HARDNESS AND DURABILITY

The RZ® SIMULANT DIAMOND has a hardness of 8.8( maximum is 9.4 from lab test), similar to a precious gem, like a Sapphire or Ruby, and should be treated with the same care. While it is incredibly hard, it is possible to accidentally damage as it is a simulant and NOT a diamond. Please click here to learn more about what a 8.8 hardness grade means. The RZ stone - because of its infused outer diamond layer - is also nearly two times harder than an ordinary CZ and will not absorb oils from the everyday use of soaps, lotions and/or beauty products.

The outer layer consisting of lab-created diamond is non-porous just like a natural diamond, so it will never cloud or discolor. Click here to learn more about cleaning and care.
