Black Silk Stone
Meaning and Properties
History
Black silk stone is an onyx marble with a beautiful, silky-smooth surface and satin finish. It features black banding that wraps around a grey-to-white background.
The Romans were experts at glyptography (the carving of layered stones to reveal different colors) and crafted beautiful seals from onyx (white layer over black base) and sardonyx (white layer over reddish-brown base). The patterns were cut in negative relief. Engravings with a negative picture are called intaglios and those with raised image are cameos. In the Middle East, onyx was associated with sorcerers.
Metaphysical Properties
Black silk stone is a nurturing gemstone. The gemstone is believed to enhance patience and clear thinking. Black silk stone is also thought to promote self-control and inner tranquility.
Geological Properties
Onyx is a form of chalcedony, which is a microcrystalline quartz formed in the gas cavities of lava. Its multi-layered structure is similar to that of agates. As with any onyx, black silk stone is found worldwide.

Designing with Black Silk Stone
The soft nature of the stone (Mohs hardness 4) makes it an ideal choice for use in short necklace and earring designs that are protected from heavy abuse.
Black is neutral, making black silk stone a great design element to combine with many different gemstone colors and all metal tones. Its deep, dark, lustrous surface can play a striking contrast to warm-colored gemstones like garnet, carnelian and coral. Or, combine black silk stone with any gemstone containing a black matrix such as lapis lazuli, rhodonite and turquoise to heighten the vein detailing.
