Sillimanite in Ruby | Gems & Gemology

 · Sillimanite itself is not a particularly uncommon mineral, especially in amphibolite host rocks, so why has it been missing from previously analyzed East African rubies at GIA? Due to its preferred habit of densely packed needles, sillimanite in ruby likely affects transparency, potentially resulting in non-gem-quality translucent to opaque rubies.
