The moonstone & black tourmaline beads are gorgeous. They are slightly larger than my other 8mm beads (purple) so I believe they are actually 9mm. They are really pretty though so I decided I'm ok with that and just ordered some in 6mm too. Pic is bottom to top: moonstone & black tourmaline 8mm, purple beads are not from this seller, dendritic opal 6mm, blue lace agate 6mm.
