Chalcedony
Microcrystalline quartz - Chalcedony
Chalcedony was so named by Agricola (1546) from a stone named after the city of Chalcedon, now called Kadıköy, a district in Istanbul, Turkey.
Data:
Formula: | SiO2 |
Color: | Colorless, white, gray, blue, any color due to embedded minerals |
Multicolored copy not unusual | |
Gloss: | Waxy |
Hardness: | 6½ - 7 |
Specific weight: | 2.6 |
Chalcedony is a non-layered Micro Crystalline variety of Quartz (not to be confused with Blue Lace Agate which is layered)
Chalcedony has different meanings.
Scientific term for Chalcedony Agates to equally large (fibrous) quartz crystals of microscopic and sub-microscopic size.
At least two types can be distinguished based on the striking behavior of thin parts of Chalcedony in polarized light:
- High-speed Chalcedony, with crystallites stacked perpendicular to the c-axis, and the resulting fibers are elongated. The fibers can be rotated around the extension axis.
- Slow Chalcedony or Quartzite, with crystallites stacked parallel to the c-axis, and the resulting fibers are elongated along, as in Macrocrystalline Quartz.
The Chalcedony Group consists of 2 subgroups; the aligned Agate group & the opaque Jasper group and its own Chalcedony group with the following: Chalcedony, Chrysoprase, Flint, Pietersiet.
If in stock you will find below my collection of Raw Gemstones within this group.

Mobile Agate 65cm
€44.44Mobile Agate Slabs natural, 6,0 - 8,5cm/ 65cm
The wind chime consists of seven agate slices in natural colours with a diameter of 7 - 8,5cm each. Overall, the agate mobile has a length of about 65cm.
Agate Mobilés - protection and decoration:
Agate wind chimes are an excellent example of the combination of Eastern and Western traditions. In Feng Shui, mobiles and wind chimes are often used to attract positive Chi'i and gently scatter in the room.
Agate has long been regarded as a protective stone in the West. Hang in the window, the mobile is a beautiful eye-catcher and is at the same time as a protective and defensive sign against negative influences from outside.
The agate mobiles are delivered complete with the wooden ring to hang.
