The foreign body is rarely spherical, so [**Fine Pearls**](https://www.poemotu.com/perles-de-tahiti/fr/31-bijoux-perles-naturelles "natural pearl jewellery") are exceptionally round, rather of baroque shape (without an axis of symmetry), and **White Pearls** are the only ones sought after, becoming the rarest and most expensive in the world. Generally with a diameter of 9 mm, the [**Fine Pearl**](https://www.poemotu.com/perles-de-tahiti/fr/31-bijoux-perles-naturelles "natural pearl jewellery") can be sold at quite exceptional prices if it is spherical and boasts a beautiful lustre (colour emanating from the **Pearl**). At the beginning of the 20th century, they traded on average for 3000 Pacific francs, equating to 15 times the monthly salary of a worker. Unfortunately, fishermen, unable to correctly estimate the value of the [**Pearls**](https://www.poemotu.com/perles-de-tahiti/fr/ "Tahitian cultured pearl jewellery") they caught, were swindled by traders who resold them at much higher prices on the American and European markets. Even today, [**Fine Pearls**](https://www.poemotu.com/perles-de-tahiti/fr/31-bijoux-perles-naturelles "natural pearl jewellery") have their enthusiasts. Paradoxically, pearl farms also produce these **Natural Pearls** when the aragonite nucleus inserted into the [**Mother of Pearl's**](https://www.poemotu.com/perles-de-tahiti/fr/ "Tahitian cultured pearl jewellery") gonad to form a [**TAHITI Cultured Pearl**](https://www.poemotu.com/perles-de-tahiti/fr/ "Tahitian cultured pearl jewellery") is rejected, and the **pearl oyster** still initiates its defence mechanism by producing [**Mother of Pearl**](https://www.poemotu.com/perles-de-tahiti/fr/ "Tahitian cultured pearl jewellery").
