† Garuda lays special stress on the high specific gravity (=4·0) of a genuine ruby. लघुत्वं विजातिलिङ्गं, again गुरुत्वं मणीनां गुणसंग्रहः । While high specific gravity is indicative of the excellence of the gems in general, in the case of diamond it is just the reverse. गुरुता सर्व्वरत्नानां गौरवाधानकारणम् । वज्रे तत् वैपरीत्येन सूरयः परिचक्षते ॥ It is not easy to account for this qualifying clause, seeing that diamond has a sp. gr. of 3·5.
