FORMATION: Blue sapphire with a natural beryllium content has been reported on several occasions, in material from a variety of sources. The best way to obtain a reference stone, to be certain about the exact origin of the beryllium in sapphire, is to go to the source.Sapphires from Tasmania are basalt related, while those from Ampasimamitaka and Sar-e-Sang are of the metamorphic type. In both types, beryllium was associated with other trace elements such as niobium, tantalum, or tungsten. These trace elements are lacking in sapphires treated with beryllium. This information should enable to distinguish blue sapphires containing natural beryllium from beryllium-treated blue sapphires. The amount of each trace element associated with beryllium is a possible key to identifying the origin of blue sapphires with natural beryllium content.
BIRTHSTONE: Sapphire is birthstone for September
UNUSUAL PROPERTIES: A stone of prosperity, Sapphire sustains life force and attracts joy and peace. Sapphire helps to open the mind to beauty and intuition. Sapphire is a stone of wisdom, with each color containing its own unique energy vibration and information.
TREATMENT: Beryllium is diffused in the sapphire to remove or lighten the blue color in overly dark sapphires. While initially doing the treatment there might be some traces of yellow color in the stone’s interior. This “yellow color” however can be removed with subsequent heat treatment, which will make the sapphire “retain” its blue color and therefore make it more marketable.
