Description: Ten pieces of prehnite from a relatively new find, ranging in length from 40 - 65 mm. Some of the pieces have bits of (possibly) limestone attached.
The pieces have been oiled to improve their colour. If they become dull after some time, you can brighten them up again with a dash of 'Cook and Spray' or liquid paraffin.
Below are random examples of those included in the lot.
