When the crystals extremely small, best to mark them with a tapearrow.
And the Matioli label ??

The mentioned crystals can be whatever, since the red brown color do not be visible even in any thin sections.
In my opinion the crystals do not show that triclinic form welshite usually have. The middle crystal have been very long before breaking, much longer than a normal welshite,
the crystal to right partly remains hexagonal.
See even pictures 1/3 and 3/3 where the specimen owner with a red-lilac pen have marked some of the brown crystals, that absolutely not are any welshite.
