This is the special dispenser bottle of refractive index liquid used by the refractometers of the International School of Gemology and others. The liquid is 1.79 which is far less toxic than the Cargill liquid at 1.81. Since there are virtually no gemstones in the 1.79 - 1.81 range, (other than garnet), the need for the more highly toxic 1.81 liquid is not required or recommended. As a result we use and recommend this 1.79 RI liquid as totally accurate for professional gemologists, which being far safer and earth friendly.
