History, Significance and Properties of Sardonyx
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.
