<p>[QUOTE="desertgem, post: 543929, member: 15199"]Tom, the same situation occurs on gemology sites.<b> How do I clean my jewel</b> is a question that occurs there as often as coin cleaning does here. Put a certain group of gemstones in an ultrasonic bath and they will shatter, use a buffer too close to some and the heat will change their color or clarity. People think diamonds are forever. Nope, they crack or chip easier than many cheap semiprecious stones. Detergents will breakdown the oils in customary emeralds, rendering them lifeless. A brown zircon will turn red or diamond clear from the heat of a couple of matches or a fast buffer wheel. Cleaning them is not for the amateur. Sure, if one wishes to educate themselves and determines which situations will allow what type of cleaning. This is different than someone saying "here is a photo of my red gem and my friend has a red gem and he did this, so can I" leads to the type of answers here. What we answer remains in archives and can be googled years from now. So as not to speak for others ~ I want my answers to be specific to a certain situation and not a " catch all". A gemstone will last longer than most coins, so gemologists are as pedantic ( or more so) as coin collectors or dealers. They aren't trying to hinder, they are trying to help.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
