Matsya Purana — The Cave-Sanctuary: Jewel-Lake
सुरोरगवलक्षाणां स्फटिकस्य तथैव च गोमेदपित्तकानां च धूलीमरकतस्य च //
suroragavalakṣāṇāṃ sphaṭikasya tathaiva ca gomedapittakānāṃ ca dhūlīmarakatasya ca //
And likewise, the text sets forth the distinguishing characteristics of the sura-stone and the serpent-stone, of sphaṭika (crystal) as well, and also of the gomedaka and pīttaka gems, and of the so-called “dusty emerald” (dhūli-marakata).
This verse does not discuss pralaya; it functions as a technical transition into describing gem categories and their identifying marks.
It supports dharmic governance and household practice by emphasizing correct identification and selection of valuable/auspicious materials—relevant for royal treasuries, donations, and procurement for temples or rites.
It signals a Vastuvidya-aligned discussion of gemstones (crystal, gomedaka, emerald types) used as auspicious substances—often relevant to consecration, ornamentation, and selecting pure materials for sacred or prestigious works.
