This product is the perfect ECONOMY RI Fluid! 

The product will NOT allow your refractometer to read between 1.791 - 1.810 Refractive Index.  How many Gemstones will you NOT be able to test?  The answer?  Very FEW.  99.0% of the other stones you can read!  This product is designed to be a cost effective alternative to the expensive 1.81 RI Fluid.  Perfect to testing ALL of your stones, while you save the good stuff (1.81RI Fluid) as a backup in case you find a blue/green spinel!

The most important aspect of the Refractometer is the quality of the fluid and its Refractive Index. This product has a Refractive Index value of 1.79 RI and is THE most economical product for accurate GEM Identification.  

The 4.0ml Vial holds about 1.8ml of product. SO THE VIAL WILL APPEAR HALF FULL!  If you need more product, we suggest buying the larger version of this product!

This liquid is repackaged and supplied in a BRAND NEW amber glass vial with applicator rod.  Vials are filled less than halfway and contain 1.8ml of solution.

To ensure the liquids maximum shelf life, keep this liquid tightly sealed after opening, store it away from direct light and in dry moderate temperatures.
