History, Significance and Properties of Sardonyx
The gemstone was especially good for engraving upon, having a hard smooth surface capable of taking a high polish, and in ancient cameos the under-stone is generally used to form the ground, the lighter top layer being carved into figures, the different depths of the carving affording variety to the effect. These qualities made it a favourite with the ancient Romans, who believed that the virtue of stones could be increased if suitably engraved. The Sardonyx was therefore frequently carved with a figure representing Mars or Hercules to render its wearer fearless and courageous. The ancients also believed that this stone had the property of preserving its wearers from infectious complaints and the bites of venomous creatures, particularly from the sting of the scorpion. If hung round the neck it would allay pain, give self-control, attract friends, ensure conjugal happiness and success in legal matters.
