In Jainism, the answer depends on who we are talking about and why the jewellery is worn.

1. For monks and nuns (sadhu–sadhvi / muni–āryikā)

• Jewellery is completely avoided.
• They take vows of aparigraha (non‑possessiveness) and tyāg (renunciation).
• Even simple ornaments are seen as possessions and also as a cause of pride, attraction, and attachment, so they are not allowed.

2. For lay Jains (shravak–shravika)

Scriptures mainly guide laypeople through principles, not fashion rules. So the question becomes:

1. Does it increase attachment (parigraha)?

- Heavy, expensive, showy jewellery usually increases ego, greed, comparison, and fear of loss. - From a Jain point of view, this is not desirable.

1. Is there himsā (violence) involved?

- Mining of gold, diamonds, gemstones etc. involves a lot of violence to countless small beings and often harm to workers as well. - A Jain trying to live with ahimsā should think seriously about this.

1. Is it worn for show or simple use?

- Very simple, minimal ornaments, without show‑off, are generally seen as more acceptable for a grahastha (householder). - Wearing jewellery only for social pressure or display goes against the inner spirit of Jain dharma.

3. Practical guideline for a Jain

If you are a lay Jain and wondering “Should I wear jewellery?” use these steps:

• Reduce: If you already wear a lot, start cutting down the quantity and cost.
• Simplify: Prefer plain, simple designs over flashy ones.
• Avoid show‑off: Do not wear it to create attraction, jealousy, or status.
• Think of ahimsā: Be aware of the violence behind what you buy; if possible, avoid or at least minimise such items.
• Strengthen inner beauty: Remember, Jain dharma praises guṇa–shobha (beauty of virtues), not alankār–shobha (beauty of ornaments).

Short answer

• Monks/nuns: Jewellery – no.
• Lay Jains: Best is to avoid or keep it very minimal, simple, and without attachment. The more one moves towards simplicity, the closer one comes to the ideal Jain way of life.
