A Simple Approach to Detecting Diamond Simulants
Contrasting the physical properties of diamond with colourless specimens to identify the most problematic diamond simulants.
Characterisation of Colourless Coated Cubic Zirconia (Diamantine)
Over the past several years, diamond simulants have entered the market that consist of colourless cubic zirconia reportedly coated with a thin layer (e.g. represented to be 30–50 nm) of nanocrystalline diamond particles embedded in a matrix.
