ASET ® Tools
Newton's is proud to utilize The American Gem Society ASET® device. It provides a quick and easy — yet sophisticated — way to assess a diamond’s interaction with light. The name ASET® stands for Angular Spectrum Evaluation Tool, and the device was developed to be used with the performance-based American Gem Society Diamond Cut Grading System.
