Rutile-titanium dioxide 20250423 100702 (1)

Rutile, Royal Ontario Museum mineral collection. Rutile is titanium dioxide (TiO2).
"Rutile has one of the highest refractive indices at visible wavelengths of any known crystal and also exhibits a particularly large birefringence (splits a ray of light into two beams) and high dispersion (rainbow effect)."
(FROM en.wikipedia.org/wiki/Rutile )

Birefringence such a good word. Spellcheck wants to correct it to bore fringe celebrities; there are many of those, of course, but they are nothing like this refractive beauty.
