About PadparadschaHide

Formula:
Al2O3
Colour:
'apricot' and 'pink' in colour, and usually has a slight brownish tinge also
Name:
The term was derived through the Gernlan language from padmaragaya (padma = lotus, raga = color), the yellow-pink Oriental lotus (nelumbo nucifera).
A variety of Sapphire

A salmon-pink coloured gem sapphire.

It is GIA's opinion that this color range should be limited to light to medium tones of pinlzish orange to orange-pinlz hues. Lacking delicacy, the dark brownish orange or even medium brownish orange tones of corundum from East Africa would not qualify under this definition. Deep orangy red sapphires, likewise, would not qualify as fitting the term padparadscha. see: Crowningshield (1983)
