Blue chalcedony is a stunning gemstone with a unique blue colour that has captured the attention of humans for centuries. This gemstone is a type of microcrystalline quartz that forms in a variety of settings including volcanic vents, hot springs and sedimentary rocks. In this blog post, we will explore blue chalcedony from a scientific perspective including its formation, properties and uses.
How Does Blue Chalcedony Form?
Blue chalcedony forms through a process called precipitation which occurs when dissolved silica in water comes out of solution and forms tiny crystals. This process can take place in a variety of settings including volcanic vents, hot springs and sedimentary rocks. The blue colour of blue chalcedony is often caused by the presence of trace amounts of copper or other minerals in the crystal structure.
What Are The Properties Of Blue Chalcedony?
Blue chalcedony has a hardness of 6.5 to 7 on the Mohs scale which means it is relatively durable and can be polished to a high shine. It has a specific gravity of 2.6 to 2.7 which is slightly lower than that of quartz. Blue chalcedony is also known for its waxy lustre which is caused by the microscopic crystals that make up the stone.
In terms of optical properties, blue chalcedony is usually translucent to opaque and has a vitreous to greasy lustre. It is also birefringent which means it splits light into two rays that travel at different speeds through the stone. This can cause a range of optical effects including double refraction and colour zoning.
The Uses Of Blue Chalcedony.
Blue chalcedony has been used for a wide range of purposes throughout history, from jewellery and decorative objects to medicinal remedies and industrial applications. Some of the most common uses of blue chalcedony include:
- Jewellery: Blue chalcedony is a popular gemstone for jewellery, especially in the form of beads, cabochons and pendants. Its unique blue colour and translucency make it a striking choice for designers and collectors alike.
