The chemical nature and composition of the growth medium of monocrystalline (MC) diamonds is still a matter of debate, partially because carbonate-bearing high-density fluids (HDFs) that are common in fibrous diamonds have not been found in MC diamon

Infrared (IR) absorption was used to measure the concentration of secondary phases trapped in microinclusion-bearing diamonds. Using KBr pellets with known concentrations, we determined the IR absorptivities ( e , AU∙l/mol∙ cm) of calcite, dolomi

We report major, trace and volatile element compositions for seven coated diamonds from Kankan, Guinea. Four diamonds trapped microinclusions with high-Mg carbonatitic high-density fluids (HDFs) and three carry silicic to low-Mg carbonatitic HDFs. Mi

Optical absorption (OA) and electron spin resonance measurements have been performed on IIa, Ib, IaA and IaB type diamonds irradiated by 3 MeV electrons. OA reveals that the GR1 system in diamond is usually accompanied by an underlying broad backgrou

Topographic infrared and photoluminescence spectroscopy of synthetic single-crystal diamonds revealed that a higher growth rate increases the concentration of Ni and Co impurities in {111} growth sectors and of N impurities in {001} growth sectors. A

High-temperature annealing of type IaB diamonds containing platelets caused the conversion of the platelets to dislocation loops and the formation of octahedral shaped defects [T. Evans, I. Kiflawi, W. Luyten, G. Van Tendeloo, G.S. Woods, Proc. R. So

Using infra-red absorption topographic spectroscopy the aggregation of nitrogen in synthetic diamonds grown with a nickel catalyst was investigated. It was found: (a) that the rate of aggregation is a function of the nickel concentration, showing con
