Gem-n-Eye Digital Refractometer

Measures the Refractive Index of unknown Gems so that you can confirm their identity. Unlike a traditional critical angle refractometer, the Gem-n-Eye requires no toxic fluid, and gives a digital readout in the form of a Refractive Index to 3 decimal places, along with the Gemstone names that share that RI value! The Gem-n-Eye does this by measuring Reflectivity, a property closely related to Refractive Index, and through a sophisticated algorithm, converts that to a familiar Refractive Index value, and then conducts a lookup within its internal database to find and display the matching gem (s) - no need to convert values or cross reference to separate charts, or plug into a computer, because the Gem-n-Eye already _is_ a computer. To use the Gem-n-Eye, just place the gemstone over the optical eye of the sensor, cover it with the included light shield, and press a button. You're done! You get a readout of the RI value and a list of those Gemstones that match - for example, RI = 2.417; Diamond, or for instance, RI = 1.698; Peridot, Tanzanite. Then push the button once more to bring up the entire data on any one of those gemstones to assist in secondary testing. The Gem-n-Eye is "Made in the USA", and comes with a 30 Day Money Back Guarantee.
