Ants try to steal a silver necklace with diamonds in Langkawi in Malaysia in 2015

Looking at the ants trying to steal the silver chain of a tourist with a diamond pendant !! He took it off before taking a holiday shower in Langkawi.

Ants try to steal a silver necklace with diamonds, note the coordination of these to move this heavy object (in proportion to the size and weight of them).

It is not clear why this behavior, but it has also been observed to individuals of several species of ants (mainly in dry areas) transport small pieces of quartz and some crystals.
