Ratna-parīkṣā: Vajra (Diamond/Thunderbolt) — Origin, Types, Testing, Defects, Weights, and Royal Auspiciousness
यदि वज्रमपेतसर्वदोषं बिभृयात्तण्डुलविंशतिं गुरुत्वे / मणिशास्त्रविदो वदन्ति तस्य द्विगुणं रूपकलक्षमग्रमूल्यम्
yadi vajramapetasarvadoṣaṃ bibhṛyāttaṇḍulaviṃśatiṃ gurutve / maṇiśāstravido vadanti tasya dviguṇaṃ rūpakalakṣamagramūlyam
If a flawless diamond—free from every defect—should weigh twenty grains of rice, the experts in the science of gems declare its foremost price to be double: two lakhs of rūpakas.
Lord Vishnu (in instruction to Garuda/Vinata-putra, within a descriptive section on gem valuation)
Concept: Śāstra-based standards (pramāṇa) govern value; defectlessness and correct weight determine rightful price.
Vedantic Theme: Respect for pramāṇa (authoritative means of knowledge) in worldly dealings; order (ṛta-like regularity) in valuation.
Application: Use standardized measures and expert verification; prioritize quality (freedom from defects) before price; avoid fraud in trade.
Primary Rasa: shanta
Secondary Rasa: adbhuta
Related Themes: Garuda Purana 1.68 (ratna-parīkṣā: doṣa, guṇa, māna, mūlya)
This verse preserves a traditional maṇi-śāstra standard: a flawless diamond of a specified weight is assigned a premium monetary value, showing how the Purana also records practical knowledge like gem appraisal.
It does not address the soul’s journey or afterlife themes; it belongs to a chapter focused on gemological measurement and pricing.
Use the verse as a historical reference for how quality (freedom from defects) and standardized weight measures determined value—an early framework analogous to modern grading and pricing.
