<p>[QUOTE=&quot;Jeff Drum, post: 429980, member: 6444&quot;]The test done at most jewelers/scrappers is to make a deep scratch and test that with acid. Testing just the surface is useless. The scratch and acid damages the piece, but if you want to scrap it anyway it doesn&#039;t matter. I never do that, however.</p><p><br /></p><p>You can also do a home test of specific gravity. This requires an accurate scale, and suspending the piece in water. Its kind of a PITA to set up, but once you have the setup you can run several pieces that you have questions about. Specific gravity would work well on this piece, but doesn&#039;t work for weighted pieces, hollow pieces or pieces with non-silver handles, etc. You need to be sure you don&#039;t have trapped air bubbles in or on the piece.</p><p><br /></p><p>I have heard that there are jewelers/scrappers with XRF (Xray fluorescence) testers that is also supposed to be non-destructive, but I have never found anyone with one of these myself. But that is a good option if you can find one.[/QUOTE]</p><p><br /></p>
