• ✅ Use available white light — The method works with a suitable external light source.
• ✅ Store the optics separately — A synthetic-leather case is included.

One observation within a wider identification process

Hold the tool at the stated 2–5 cm viewing distance and follow an appropriate observation method. Results depend on the gemstone, orientation and lighting.

A dichroscope does not alone certify identity or authenticity. The black metal body has an approximately 20–21 mm lens reference and needs no battery.
