I add the comment by Jon Larsen:
“Colourful spherules of unknown origin, found by Giuliano Bettini at [489] Rosignano Marittimo, Italy.
After nearly 500 field searches around the world, we have never seen anything like the amazing, colourful spherules from Giuliano Bettini's collection. He has published an article about them: http://vixra.org/pdf/1103.0101v1.pdf
The origin of these nonmagnetic spherules is uncertain, but with so many different and strong colours together, and with all the spherules found in one small area, the suspicion goes in one particular direction - chemistry at its most entertaining: Pyrotechnics.
In fireworks and flares various exotic metal salts (mainly carbonates and chlorides) are used for colorisation: strontium/lithium (red), calcium (orange), sodium (yellow), barium (green), aluminum/titanium/magnesium (silver/white), copper (blue), and so on. However, we have not seen anything like the Bettini collection before.
At the same location Bettini also found green glass droplets (similar to the controversial, Russian "volkhovites"), and a few I-type (iron) magnetic spherules - possibly of extraterrestrial provenance.
Thanks to Giuliano Bettini for sharing these with us.“
