Cobalt-bearing glass imitations are still appearing in the gem market in all shapes, sizes and color shades to imitate mainstream colored stones. Watch out for these imitations in Southeast Asia + South Asia + East Africa + alluvial sources. The specimens may have the look and character of the real stones.
Usually 'momentary autism' does the trick because you think you have the right stone + you are in a hurry; you are stitched!
