Repost from last year:
I've seen sphene! (Sounds better than "the rock is tippsy with titanite")Centimeter-size black sphene (titanite) with apatite (dark brown) and orthoclase feldspar (light brown). Folding pocket knife for scale.
From the Bancroft locality in Ontario, Canada. Grenville-aged (~1.2± billion years)

A titanite lozenge imaged both using a cellphone through the microscope ocular, and with a proper imaging system. It's surrounded mostly by quartz (+feldspar).
Likely from the Grenville, but from a teaching collection two generations of retired professors ago.
