HISTORY: Sapphire has been associated with royalty for centuries, often decorating robes of royalty and clergy as the fairytale gemstone. The precious gem is known for its association to royalty and romance, reinforced in 1981 when Britain’s Prince Charles gave a blue sapphire engagement ring to Princess Diana. Her personality and charm captivated the world and her sapphire ring was admired by all until her death on August 31, 1997. In July of 2010, Princess Di’s son Prince William proposed to Kate Middleton using his mother’s 18-carat sapphire and diamond engagement ring. Sapphire comes from the Greek word sappheiros. In ancient Greece and Rome, kings and queens believed sapphire would protect them from envy and harm. Today Sapphire’s extraordinary blue color is used as the standard to compare other blue gemstones.
FASHION: Sapphire is a great stone to wear daily, as it is a 9 on the MOHs hardness scale (out of 10). It is also a great gemstone to pair with diamonds. The beautiful blue hues and the sparkling white diamonds just dance perfectly together. Whether you are wearing your little black dress, a beautiful gown, or maybe your favorite jeans and t-shirt, you can’t go wrong with sapphire jewelry. Now if the “traditional” blue sapphire doesn’t work for you – pick any other color you’d like: red, yellow, orange, green…no really, sapphires are available in most every color of the rainbow!
FORMATION: Sapphires form within the earth by shifts in heat and pressure and are found in metamorphic and igneous rocks. Sapphires may also be found in alluvium deposits.
CLEANING & CARE: Sapphire can easily be cleaned at home with warm, soapy water and a soft brush. Ultrasonic and steam cleaner may be used for untreated stones. Fracture-filled, cavity-filled, or dyed stones should only be cleaned with a damp cloth. Care should be taken in avoiding exposure to extreme heat and chemicals.
TREATMENTS: Sapphires are often heat treated to achieve the beloved blue color.
