Royal Kings Plain Sapphire®

Color:   Rich royal blue to navy blue
   
Gem Family:   Royal Kings Plain Sapphire® is a member of the corundum family, which includes both ruby and sapphire.
   
Source:   This rare sapphire is mined in the Australian state of New South Wales. The Kings Plain Mine is actually an ancient dry riverbed where sapphire was washed centuries ago from deposits in hard rock somewhere in the area. Most sapphire found in these gem gravels ranges from the size from a grain of sand to a pea. Rarely, larger size gems are found. After an area is mined, the land is reclaimed into lush pastures.
   
Clarity:   Ranges from no visible inclusions to moderately included.
   
Size Range:   Small accent stones to spectacular 2-carat gems.
   
Shapes Available:   Royal Kings Plain Sapphire® is exceptionally well cut for corundum, which is so valuable that many producers sacrifice brilliance for weight. Royal Kings Plain Sapphire® is available in a variety of shapes including brilliant and Portuguese rounds, emerald cuts, ovals, princess cuts, and trillions.
   
Enhancement:   Royal Kings Plain Sapphire® is enhanced by heat to remove green overtones from the rich blue color. Heat enhancement is stable, routine, and does not require special care.
   
Lore & History:   Sapphire comes from the Greek word for blue, sappheiros, and this gem provides the most beautiful blues of the gem kingdom. The ancient Persians believed the earth rests on a giant sapphire. Its reflection, they said, made the sky blue. Sapphire is the original "true blue": the gem of fidelity and of the soul. In ancient times, a gift of a sapphire was a pledge of trust, honesty, purity, and loyalty. This tradition makes sapphire a popular choice for engagement rings.
   
Toughness & Hardness:   Sapphire has a hardness of 9 on the Mohs scale and it is quite tough.
   
Care & Cleaning:   Sapphire is among the most durable gemstones. In its common form, corundum is even used as an abrasive! Clean your sapphire with warm water, detergent, and a soft brush. Royal Kings Plain Sapphire® can be put in ultrasonic or steam cleaners.
   
Special Characteristics:   At the Kings Plain Mine, miners move ten cubic meters of earth, a car-size chunk of rock, to find 2 carats of Royal Kings Plain Sapphire®.
