Latest Patents
One of Ashman's latest patents focuses on a method and means of rapidly distinguishing a simulated diamond from a natural diamond. This invention addresses the challenge posed by simulated diamonds, such as crystalline cubic zirconia, which possess optical properties very similar to those of natural diamonds. The patented method involves measuring the thermal conductivity of the simulated diamond, which is significantly different from that of natural diamonds. By utilizing a heated probe held against the simulated diamond, the temperature of the probe is detected as an indication of the simulated diamond's thermal conductivity compared to that of natural diamonds. This innovative approach provides a reliable means of differentiation.
