Yes I agree they're greyish blue and didn't mean to imply otherwise, which is why I said they're not grey-blue. You know how with FCDs a modifier can be, for example, greenish yellow or green yellow, with the latter being more green than the former. I suppose not everyone defaults to this, so thats my bad for being unclear.
I bought up those blue Tanzanian spinels since it was mentioned blue and violet spinels are getting harder to source, and this vendor posted that there is a new source.
Clearly, I misunderstood that posters were referring to the really fine blue colors. I tried to google about tanzanite-like blue Tanzanian spinels which were mentioned here but couldn't. @TL if you have more info I'd love to know.
Huge pet peeve of mine with every blue spinel being called cobalt blue. There are also those extremely dark stones that are called cobalt blue. They may be colored by cobalt (dunno), but are not that desirable color imo. Maybe some consider it cobalt? GRS certainly does, which isn't surprising

Sorry @cocobianco for this threadjack
They’ve been abusing the “cobalt blue” metaphor for a long time.
Tanzania produced some really nice violet and blue spinels a while back, about 10 to 15 years ago. Some even rival the gorgeous violets coming out of Vietnam. Many nowadays are very gray. Here’s the most accurate photos I could muster of this medium toned Tanzanian spinel in day and artificial light that also flashes pink sparkles. Is there gray, yes, but it’s not overly gray. I’m not bashing gray spinels here, I just only see more grayish stones on the market, maybe due to consumer demand???
