Pushparaj:

Yellow or white sapphire, also called pushparaj. The stone in its purest form should have eight qualities : it must feel heavy when placed on the palm of the hand, appear clean, pure, be free of spots, should be solid with no layer, have a yellow hue, feel xmooth to touch and its radiance must improve when rubbed on a testing stone. A pushparaj with blemishes like a blackish tinge, asymmetry, spot or a whitish-yellow coloring is regarded inaupicious and is not used in jewellery.
