Most attractive to the eyes, the diamond is famous for its play of colors. It emits a very delicate bluish, reddish, or a mixture of blue and red radiance of glittering lustre when exposed to light. The gem is luminous and dazzling, and emits sparks of light. A fine diamond is effulgent, radiant, and delightful. It is as soothing to the eyes as the Moon; it is lovely and magnificent and has the self-luminous quality of a clear crystal. It is brilliant and radiates rainbows of light all around. Ancient Hindu scriptures mention eight types of diamonds. They are Hanspati, Kamlapati, Vasanti, Vajraneel, Vanaspati, Sbyamvajra, Telia, and Sanloyi.
