The VeriGem® machine is used for direct measurement of light behavior and for fingerprinting (registration and verification) of diamonds by gem labs, retailers, diamond manufacturers, wholesalers and appraisers. This machine can be used for both: loose and mounted diamonds!
ImaGem’s patented direct measurement technology actually measures the brilliance, sparkle and intensity of a diamond to assign an overall light behavior grade. Numerical measures and grades are given on this basis. Processing time for each diamond is about 40 seconds and a certificate is printed on-site immediately after processing is complete.
The fingerprinting process involves two steps – registration of a diamond and verification to confirm its identity. This service takes between 40-60 seconds depending on the exact service selected. ImaGem uses its patented direct measurement technology and special imaging techniques to record a diamond’s identity and save it to a database for future verification. To verify a diamond, the stone’s weight, total depth and gem id number are used in combination with several other measurements.
A complete list of services available through the VeriGem machine is given below.
VeriGem services are available for round and fancy shape diamonds. If you require our services for a very special and unusual diamond cut, just call and we’ll be happy to work with you to develop it.
