Gemmologi

En samling ädelstenar.

Gemmologi är läran om ädelstenar. Uttrycket härstammar från det latinska ordet gemma som betyder juvel och det grekiska ordet logos som betyder lära. Gemmologer är personer som har specialiserat sig på identifiering av ädelstenar.

A selection of gem pebbles made by tumbling rough stones with abrasive in a rotating drum.

The picture was made without use of a camera, simply by arranging the pebbles on the glass of my flat bed scanner.
