Sky Blue Chalcedony Polished Collectible Semi-Precious Gemstone
This Gemstones unique colour and shine make it a must-have for any gem enthusiast.
The beautiful blue hue of the stone occurs due to the “Tyndall effect”, which is defined as light scattering by colloid sized particles, resulting in colours ranging from a light transparent blue to a solid baby or sky blue.
Blue Chalcedony is a rare variety of Chalcedony. It is a cryptocrystalline silicate mineral and a member of the Quartz family and occurs in large mass formation which is perfect for cutting, crafting and tumbling.
The Chalcedony on the market today comes from a single region in Turkey and the area is believed to have been extracting Blue Chalcedony since 2500 B.C.
The word "Chalcedony" derives from the ancient sea port of Chalcedon, now known as the city of Kadikoy of the Istanbul Province.
