With covering the full range from 1.30 to 2.99RI, It is an ideal instrument to identify the gem stones. The importance is that it can test the gem stones without requiring ANY messy, damaging contact oil. *Specification: -RI Test Range:1.30 to 2.99RI -Power Input: 9V Battery -Work Tempreature: 25-28oC *RefractiveIndexofSomeGemstone -Quartz:1.544-1.558RI -Topaz:1.63-1.64RI -Ruby:1.74-1.78RI -CubicZirconia:2.15-2.18RI -Diamond:2.37-2.46RI
