<p>[QUOTE=&quot;all_fakes, post: 379382, member: 55&quot;]I&#039;m still tending toward a collection of beach agates; but yes, a good photo of the broken face would help; agate usually shows conchoidal fractures.&nbsp; Someone with a rock tumbler might well have agates, some polished, some not - I certainly do.....</p><p><br /></p><p>The polished ones are too smooth to have been naturally polished, and agate is far more commonly tumbled than fluorite or citrine.&nbsp;&nbsp; Some beaches have a more yellowish character to their agates than others, so the color does not rule out beach agate.&nbsp;&nbsp; One could do a hardness test, or see what scratches them, and what they scratch, if one had some samples of other rocks to compare. Fluorite has a hardness of Mohs 4; citrine is 7, and agate about the same, 6.5-7.&nbsp; Glass is 5.5, so agate or citrine will scratch glass, but glass will scratch fluorite.</p><p>In my area it would be pretty hard to find a collection this size of fluorite or citrine, by scavenging beaches.[/QUOTE]</p><p><br /></p>
