How to approach this question
Think about the properties needed for a material to be used in jewellery. It should look good and be long-lasting. What chemical and physical properties does this imply?
Full Answer
It is unreactive / does not corrode / is shiny / is rare.
Platinum is used for jewellery for several reasons related to its properties:\n- **Chemical property:** It is very unreactive. This means it does not corrode, tarnish, or react with skin, so it stays shiny and lasts a long time.\n- **Physical properties:** It has a shiny, silvery appearance (it is lustrous), which is aesthetically pleasing. It is also rare and valuable, which makes it desirable for luxury items.

✗ Giving a generic property of metals like "strong" or "conducts electricity" which is not the primary reason for its use in jewellery.
