Chalcedony is a type of microcrystalline quartz that is white when pure. Trace elements or inclusions of other minerals give it a range of colors. This beautiful scarab has a creamy sheen, giving it a soft glow. It has been dated to the 18th Dynasty (1551-1347 BC) and is mounted in 18K gold to protect it.
The 18″ necklace was crafted out of 18K handmade gold tube beads with sapphire rondels. Although sapphires were not used in ancient Egyptian jewelry they are a good choice for their toughness and durability, occurring naturally in a wide range of colors. Red sapphires are known as rubies whereas we typically think of sapphires as being blue, but all colors are corundum, second in hardness only to diamonds. Their colors are determined by trace amounts of elements such as iron, titanium, chromium, copper, or magnesium. The paler hues of the sapphires in the necklace were chosen to match the delicate highlights on surface of the scarab.
