Crystals by Planet

asterwise_get_crystal_by_planet
Read-onlyIdempotent

Returns all crystals associated with a specific Vedic planet. Results are sorted with primary Navaratna gems first, then Uparatna substitutes. Only Navaratna and Uparatna Vedic assignments are returned — crystals with no Vedic planetary correspondence are excluded.

WORKFLOW: BEFORE: RECOMMENDED — asterwise_get_natal_chart — identify the planet needing remediation. AFTER: asterwise_get_gemstone_recommendations — for chart-specific gem safety assessment.

INPUT CONTRACT: planet: One of Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, Ketu.

DO NOT CONFUSE WITH: asterwise_get_gemstone_recommendations — natal chart house-lordship gem recommendation with contraindications; use for actual gem prescription, not just listing. asterwise_get_crystals — all 54 crystals including Western-only ones.
