Dialdex need to know the refractive index to overcome almandine garnet doublet and a synthetic blue spinel?
I think the IR is a unique property of a mineral that will not change if you use different refractometers. Ref almandine index is 1.730 to 1.760 natural spinel is generally an index of refraction of 1.71, while synthesis of RI is greater, 1.72-1.73
