Like jet, it&#039;s lightweight and warm or room temperature to the touch. But while it can be polished to a nice sheen, vulcanite is never quite as glossy as actual jet. Most vulcanite pieces are molded, as opposed to carved, and might seem more espresso-colored than black - the material turns brown over time and exposure to sunlight. Stockhammer offers this tip: When rubbed against unglazed tile, vulcanite leaves a brown streak (but such tests should be performed carefully to avoid damaging the surface of a piece of jewelry).</p><p><img src="http://media-cache-ec0.pinimg.com/736x/a1/94/11/a19411314bb4fbbfd7c8cc9448b847b0.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
