| description | An apparatus for picking up cut gemstones which have been orientated table down includes a vacuum wand 20 having a generally cylindrical body 22 with a central bore 18 culminating in a nozzle 24 through which a vacuum may be applied, a retractable outer sleeve 23 configured to slide axially over the nozzle 24 and a biasing mechanism 25 for biasing the sleeve 23 towards a position in which it extends beyond the nozzle 24. Flat surfaces 36 on the body 22 and sleeve 23 may prevent relative rotation. Contact surfaces 26, 27 at the lower end of the body 22 and sleeve 23 may be tapered inwards to retain a relatively small or larger cut gemstone respectively. Contact surfaces 26, 27 may include transverse profiled grooves 28, 29. Outer sleeve 23 may retract from a position level with or below the nozzle 24 to a position above the nozzle, biased by a spring 25. Retraction of sleeve 25 may be limited by a shoulder 35. |
