A manufactured gem material consisting of two or more distinct parts is often marketed as a diamond alternative. Typically, a thin layer of lab-grown or natural diamond is adhered to a core material, such as cubic zirconia or moissanite. This construction aims to provide the appearance of a solid diamond at a lower cost. The layered structure differentiates it from single-material gemstones.
The creation of such materials allows for access to larger-appearing stones for consumers on a budget. By utilizing less actual diamond material, manufacturers can offer jewelry with a similar aesthetic at a fraction of the price of a comparable, traditionally mined diamond. Historically, this approach has been used to mimic the brilliance and fire of diamonds, offering a more affordable option.
