It seems that Ruby, Spinel and Feldspar occur together with tourmaline in Minh Tien, you can refer to the paper: Update on Gemstone Mining in Luc Yen, Vietnam by Pham Van Long, Vincent Pardieu and Gaston Giuliani in Gems & Gemstone Winter 2013, in particular Fig.4 and pages 235-236 of the paper.
I have also brought here in HCMC a very nice sample coming from Minh Tien with few quite big spinel crystals with muscovite, see attachments.
Hope this could be of help.
Best regards
Mario
