The Gem Refractometer Liquid has a refractive index of nD = 1.800, the second highest of any liquid not containing arsenic. As the name implies, it is widely used with gem refractometers as a contact medium for the identification of gemstones. This Burgundy liquid can also be used to reduce or eliminate glare from a gem's surface, facilitating inspection of the gem's interior for inclusions and other defects. This liquid is repackaged and supplied in a NEW amber glass vial with applicator rod. 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 (Room Temperature). This product is the non-poisonous version of the classic Gem Refractive Index Fluid; Diiodomethane (methylene iodide). It is not carcinogenic (won't cause cancer) according the the product MSDS.
