Comment: This 0.71 is different from the others: Less or no vanadium made it yellow, almost orange but not green, and its needle inclusions are so thick and dense that it borders to 'moderately included', though we still need the lens to discover how the fire becomes a glow. That is what we have: a yellow-orange glow instead of distinct red-green-yellow sparks. If he hadn't come with the vanadium-green others, I would have guessed it to be an Afghani or Pakistani titanite which have higher FE content and get orange to brown. That said, a nice little gem for the bargain hunter, charming sunny colour, interesting study under the lens, and a surprising sparkler for a ring or a petite pendant.
