With that being said, let’s dive in and explore what sets sardonyx and onyx apart.
Geology of Sardonyx and Onyx
Sardonyx and onyx are two distinct gemstones that are often confused with each other. Despite their similarities, these gemstones have different geologic origins and mineral compositions that set them apart. Understanding the geology of sardonyx and onyx can help buyers distinguish between these gemstones and make informed purchasing decisions.
- Sardonyx geology: Sardonyx is a banded chalcedony mineral that is formed from agate and carnelian. It is a microcrystalline quartz, which means that its crystals are too small to be seen by the naked eye. Sardonyx is usually composed of silica, which comes from the weathering of rocks that contain silicon. Sardonyx is known for its white or pinkish-white bands that alternate with black or brown bands. These bands are caused by the deposition of different mineral layers in the silica solution that forms the gemstone.
- Onyx geology: Onyx is also a banded chalcedony mineral, but it is different from sardonyx in its composition and origin. Onyx is formed from the deposition of calcium carbonate in caves and other similar environments. It is a sedimentary rock that is composed of aragonite or calcite minerals. Onyx may exhibit bands of different colors, but it is usually black or white.
The geologic differences between sardonyx and onyx can be seen in their physical properties as well. Sardonyx is usually harder (7 on the Mohs scale) and denser than onyx (6-7 on the Mohs scale). Sardonyx is also more durable than onyx and less prone to breaking or chipping. Onyx, on the other hand, has a more translucent and gel-like appearance than sardonyx, which has a higher degree of transparency and a more glassy appearance.
Overall, understanding the geology of sardonyx and onyx can help gemstone enthusiasts and buyers appreciate the unique characteristics of each gemstone and differentiate between them. While both are stunning gemstones, they do have distinct origins, chemical compositions and physical properties that make them unique.
Physical Characteristics Comparison of Onyx and Sardonyx
Onyx and sardonyx are two types of chalcedony stones. Both stones are often used for decorative purposes, such as in jewelry making, but they differ in their physical characteristics. Here is a comparison of their physical properties:
- Onyx is a banded variety of chalcedony that is typically black or white with parallel bands. Sardonyx, on the other hand, has reddish-brown bands.
- Both stones have a hardness of 7 on the Mohs scale, making them relatively durable, but onyx is slightly harder than sardonyx.
- The specific gravity of onyx is 2.65, while that of sardonyx is slightly higher at 2.67.
- Onyx is a cryptocrystalline stone, meaning its crystals are so small they cannot be seen with the naked eye. Sardonyx, on the other hand, has visible crystalline structures.
Overall, while both onyx and sardonyx are chalcedony stones that share some similarities, they have unique physical characteristics that make them stand out from each other.
