The Gem Master 1.81 fluid allows the testing of gemstones with higher refractive indices, such as garnets. Safely contained in a spill-minimising bottle, this fluid releases very few vapours and has a long lasting shelf life. The advanced formula allows for less crystallisation than 1.79 fluid even at lower temperatures.
We are open from Monday to Friday.
