Calcite Dichroscope Gem Tester – Identify Pleochroism in Gemstones

Calcite Dichroscope – Gemstone Pleochroism & Identification Tool
This calcite dichroscope is a professional gemological instrument designed to reveal pleochroism—the ability of certain gemstones to show two different colors when viewed from different angles. This natural property helps gemologists quickly separate similar stones, such as ruby from red garnet, or distinguish tourmaline, iolite, sapphire, and many more.

Using a high-quality calcite crystal, this dichroscope produces two clear pleochroic images, allowing accurate and fast gemstone screening. With experience, some gemstones can be confidently identified using pleochroism alone (though confirmatory tests are always recommended).

Built with a durable metal casing, this pocket-sized tool is reliable, portable, and ideal for gemstone buyers, jewelers, and students of gemology.
