Arrange the sentences into the correct order.
Put the sentences in the correct order:
- The finest specimens are set aside for jewellery, while irregular ones are sold for lower-value ornamental uses.
- Only after this lengthy waiting period are the shells opened and the pearls extracted, sorted by size, shape, and sheen.
- Farmers then return the treated oysters to submerged cages, where they must be tended for one to three years while the coating thickens.
- In response, the oyster coats the irritant with layer upon layer of nacre, the same lustrous substance that lines its shell.
- To begin the cultivation process, a technician inserts a small bead or piece of tissue into a living oyster, triggering the animal's natural defence mechanism.
