Indranīla (Blue Sapphire): Source-Myth, Grades, Tests, Substitutes, and Price
यस्य मध्यगता भाति नीलस्येन्द्रायुधप्रभा / तमिन्द्रनीलमित्याहुर्महार्हं भुवि दुर्लभम्
yasya madhyagatā bhāti nīlasyendrāyudhaprabhā / tamindranīlamityāhurmahārhaṃ bhuvi durlabham
எந்த நீலமணியின் நடுவில் இந்திராயுதம் போன்ற ஒளி பிரகாசிக்கிறதோ, அதுவே இந்திரநீலம் எனப்படும்; அது மிக மதிப்புமிக்கதும் பூமியில் அரிதுமானதும் ஆகும்।
Lord Vishnu (in discourse to Garuda/Vinata-putra, as typical for Garuda Purana narration)
Concept: Lakṣaṇa of true indranīla: central vajra-like brilliance (indrāyudha-prabhā) as defining mark; value grounded in intrinsic sign.
Vedantic Theme: Inner light as criterion: the ‘center’ (madhya) radiance metaphorically echoes the primacy of inner essence over outer form.
Application: Authenticate sapphire by checking for characteristic internal brilliance; treat rare valuables with ethical stewardship and avoid fraud.
Primary Rasa: adbhuta
Secondary Rasa: shanta
Type: earthly domain of acquisition (mines/treasuries implied)

This verse defines Indranīla (sapphire) by a key identifying mark—an Indra’s-vajra-like brilliance at its center—and emphasizes its rarity and high value.
It does not address the soul’s journey; it belongs to a descriptive section on valuable substances (ratnas), focusing on identification and worth rather than afterlife doctrine.
Use the verse as a traditional identification guideline: genuine value is tied to clear defining qualities, not mere appearance—apply this discernment in ethical purchasing and appraisal.
