Abstract: The present invention provides a diamond simulant with greater similarity to a diamond than cubic zirconia. The present invention further provides a diamond simulant with durability, hardness, and optical features closer to that of a genuine diamond that previously afforded by other diamond simulants, such as cubic zirconia.

Abstract: A multiplet gemstone is described having a first and a second layer of gemstone material, the first and second layers each having an interfacial surface; and wherein one of the interfacial surfaces has a translucent image printed thereon. A method of making the multiplet gemstone is described including a first step of providing a first layer of gemstone material having at least one flat surface; a second step of providing a second layer of gemstone material having at least one flat surface; a third step of direct printing a translucent image onto the flat surface of the first layer; and a fourth step of bonding the flat surface of the first layer to the flat surface of the second layer to manufacture the multiplet gemstone.
