[QUOTE="jimnyjerry, post: 566496, member: 101"] A good light shone through agates can show up cracks then you need to work around the areas that are not too badly damaged. A percentage of agates from Agate Ck have pressure cracks and fractures from bouncing around etc. Start gently at 100 when shaping then a longer time at higher diamond wheels getting shape right. Long process but worth while :) 80 can really damage the surface and stress the stone [/QUOTE]
