Bright colorful Sobral beads that were at one time a chunky necklace.  I disassembled and then didn't follow through my project.  So these cool Sobral beads would be perfect for you to get creative with or put them back together to make necklace.  They measure 1.5 cm squares.  Drops of color suspended in resin.  Not signed but I bought them from a Sobral dealer in Paris thru eBay.
