An arrangement and a method are provided for non-destructively analyzing the composition of a delicate sample. The value of the sample depends at least partly on absence of visual defects. A laser source ( 301 ) produces a pulsed laser beam, and focusing optics ( 302 ) focus said pulsed laser beam into a focal spot on the sample. A sensor ( 312 ) receives and detects optical emissions from particles of the sample excited by said pulsed laser beam. A processing subsystem ( 111 ) produces information of the composition of the sample based on the optical emissions detected by said sensor ( 312 ).
