[QUOTE="Lefty, post: 427643, member: 2976"] Cheers Dave. Have a close look at your stone under strong light (not fluro or LED - sunlight is best but incandescent works too) and see if you can detect a gold-bronze or silvery sheen as you tip and rotate it under the light. A little bit of clear, oily stuff or glucose or pale honey on the stone helps. If you're certain you can see the sheen then there's a fair chance it will throw a star. Seashells need no work, they are already perfect by nature! We used to collect cowrie shells from the rockpools at the local beach as kids, the surface of them was so glossy that you would swear someone actually [i]had[/i] polished them. [/QUOTE]
