The Diamond Sure is a small compact and easy to use instrument. It helps to determine natural diamonds from synthetics and simulants. All diamonds whether loose or mounted will undergo a screening test on the ‘Diamond Sure’ instrument, which refers any diamonds which might be a Type IIa and Type 1aB for further testing. These diamonds are susceptible to colour enhancement by high pressure high temperature (HPHT) treatment and require further testing to determine whether their colour is still natural.
