JTV has been selling that grade of blue sapphires in their cheap jewelry for years. Sometimes they label it as "midnight sapphire", and yes, you are right, it basically looks black unless you've got a 1000 watt spotlight shining on it. I'm finding myself watching less and less of JTV during this time, tired of hearing how "rare" tanzanite is, yet they and everyone else has tons__ left to sell. How "generational" it is to pass down to the grandkids yada,yada,yada…. Same thing with all of the chrome diopside JTV sells. Don't get us started on how "rare" the sleeping beauty turquoise is. Been hearing this for about 4 or 5 years,yet there's still 1000's and 1000's of carats of it being sold by all the channels????
