<p>[QUOTE="Blissskr, post: 1876957, member: 34882"]You should really spend the $20-30 it would cost to obtain a digital scale and graduated cylinder to complete very simple specific gravity testing if your worried about authenticity. As I stated in the other thread all a magnet is good for with gold is a very quick in no way accurate test of whether it sticks to the item in question or not. In which case if it does stick you can reasonably conclude the item isn't real gold or very low purity. The magnet slide test is more compatible with silver than it is with gold although both have diagmagnetic properties; the effects present are greater with silver.</p><p><br /></p><p>Gold <a href="http://periodictable.com/Elements/079/data.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://periodictable.com/Elements/079/data.html" rel="nofollow">http://periodictable.com/Elements/079/data.html</a></p><p>Silver <a href="http://periodictable.com/Elements/047/data.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://periodictable.com/Elements/047/data.html" rel="nofollow">http://periodictable.com/Elements/047/data.html</a></p><p><br /></p><p>To accurately test gold determining density is the way to go.
