Hi m42protosun and Met List member,
I am not sure that You catch a nanodiamonds. Usually they are wisible
under HRTEM microscope (High Resolution TEM) and grains was separate
under acid treatment.
Nanodiamonds form chondrites (CC, OC) have 2 - 3 nm size.
Here a exemple of separate Tagish Lake nanodiamonds powder and my
results form Raman Spectroscopy:

Also here is Daulton photo using a HRTEM of single grain form Allende :
