The 3 jewels (ratna) of Jainism are:

• samyak darśana — right faith or correct vision
• samyak jñāna — right knowledge
• samyak cāritra — right conduct

Key points:

• They are the basic path toward liberation. Typically, right faith leads to right knowledge, and together they lead to right conduct. Some traditions also emphasize a closely connected cycle where conduct grows from knowledge and faith. In many Jain texts, the order is stated as: right faith, right knowledge, then right conduct; there is also a traditional view that right conduct follows from right knowledge and right faith.
• There is a broad agreement across Digambar and Śvetāmbara traditions that these three are essential for spiritual progress. Some texts mention a related practice of ascetic discipline (samyak tap) as an additional support, but the core trio remains the same.

If you’d like, I can share the exact wording and meanings from a specific Jain scripture (with differences noted for Digambar vs. Śvetāmbara) or point you to a Jain Knowledge page that discusses the ratnatraya in more detail.
