Agatized Coral Cuff
Agatized coral is found in ancient ocean beds, where silica rich groundwater has percolated through live coral shells and over time has replaced it's calcium carbonate skeleton with a hard variety of Chalcedony. If you look closely at this stone you can see the fossilized remains of the tiny coral.
The cuff and setting for the stone are all in heavy gauge sterling silver. There is a cute little shell cut out of the back. This cuff if sized medium, and will fit a 6" wrist quite nicely. It can also be adjusted a bit up or down, but probably not to less than 5 1/2 or up above 6 1/2.
Agate is a rock consisting primarily of chalcedony, alternating with microgranular quartz. It is characterized by its fineness of grain and variety of color. Although agates may be found in various kinds of host rock, they are classically associated with volcanic rocks and can be common in certain metamorphic rocks. They are primarily translucent in nature and are frequently found hollow. Agate is extremely durable.
