Description: Ten pieces of prehnite from a relatively new find, ranging in length from 35 - 65 mm. Some of the pieces have bits of (possibly) limestone attached.
These pieces are all-natural, but if you want to improve their appearrance, you can oil them with 'Cook and Spray' or liquid paraffin. If they become dull after some time, you can brighten them up again with a dash of oil.
If you do oil them, just make sure that you put them on a surface where the oil will not cause a problem.
Below are random examples of those included in the lot.
