Empirical and arbitrary scales of weight were adopted as standards. A ruby occupying the volume of a guñja (abrus precatorius) may be equal in weight to 10, 7 and 3 guñjas respectively. A ruby of the volume of a sṛgālakola (a kind of jujube) should weigh 12, 8 and 7 guñjas respectively. Again, a ruby of the volume of an āmalakī (phyllanthus emblica) should weigh 30, 20 and 16 māshās respectively.* In each case the gem which is of greater weight is superior in quality and the value thereof is enhanced in proportion.†
