125+ Gemstones are labeled! A Gem Refractometer without a Refractive Index Chart is like a thermometer without the reference to what is hot or cold!A copy of this comes with each of our Gem Refractometers, but this listing is for a laminated version that will last a much longer time.For LARGER ORDERS, please check out our eCRATER Store!
