How GEMS work | Optical properties explained

Today we're unboxing unbelievable gems and tour their fascinating optical properties. We dive into the refractive index, fire / dispersion, brilliance, pleochroism, and double refraction / birefringence. For many of theses, seeing is believing. 00:00 - Why do gemstones look like that? 00:13 - 100 gemstones in boxes.
