You are the boss of that jewelry!</p><p><br /></p><p>On a pendant/brooch there are always edges to use. On a ring, I gently rub the side edge of the shank, never the broad side. You don&#039;t need to push too hard to make a decent mark. For a chain, just carefully hold the links and gently rub back and forth to create a mark.</p><p>The mark should be roughly 20mm by 2mm. The mark needs to be long enough to accommodate 3 drops of acid.</p><p><br /></p><p>Carefully place a small drop of 10k acid on one end of the mark. If the acid eats it away, then the piece is not gold at all, or possibly 8-9k.</p><p>If the acid doesn&#039;t eat it away, then add a drop of 14k next to it, but not touching.&nbsp; Don&#039;t let the drops run together.</p><p><br /></p><p>If the mark still doesn&#039;t get eaten away, then add a drop of 18k. When the mark stays intact under the acid, then that is what karat the item is.</p><p>After testing, wipe the stone clean with a wet paper towel.</p><p>And don&#039;t get the acid on your skin--it burns!</p><p>You will have lots of fun testing your gold![/QUOTE]</p><p><br /></p>
