The Sherlock Holmes Detector is a portable desktop diamond verification instrument for loose and mounted stones. The Sherlock Holmes Detector is designed to separate natural diamonds from synthetic diamonds. The unit is manually operated and requires an operator to interpret the test results. The Sherlock Holmes Detector is indubitably suitable for an environment where you need to test both mounted and loose diamonds e.g. dealers, diamond and jewelry manufacturers, retailers, pawnbrokers, buyers and gemmological laboratories.
