The diameter of the pearls

The diameter of a pearl is one if not the main factor in the enhancement of a pearl. Indeed, the pearls that are the most expensive today are the largest pearls. On the contrary, the cheapest pearls, the cheapest ones are smaller pearls.

This value of the large pearl, with a high diameter comes in particular from the reason for its size. Indeed, the larger a pearl has a diameter, the higher its creative time within the oyster. It is therefore normal that these pearls are more expensive. More oysters are monopolized to produce large pearls. Especially since only certain oysters can produce pearls of more than 20 millimetres for example.

There is therefore a real rarity of large pearls and the more their size increases, the more their value increases.

Today the majority of Tahitian pearls sold, accessible to almost all, measure between 7 and 8 millimeters on average. However, this figure can increase considerably for star pearls, for example at the Cannes Film Festival. The pearls no longer form a necklace but are no longer used one by one for a bracelet or pendant.

In the necklaces and jewelry we offer, we always strive to establish continuity, regularity in our offer. Thus, the pearls of our necklaces have only 0.5 millimeters of variation in diameter. This regularity and consistency allows for a certain harmony and a more beautiful aesthetic.

Different tahitian pearl sizes

The size of pearls has a special meaning in the cultivation of the farmers and pearl fishermen. Indeed at each age of life, pearls with a specific diameter were associated.

So the older you get, the bigger you can wear pearls.

From the age of 16, the pearls are 4.5 to 6 millimetres long, then grow to more than 14 millimetres beyond 40 years.

The size of a pearl is measured by specialists. Objects exist to measure these pearls. Each pearl is measured systematically several times to ensure the right size and thus give a real value to the pearl.

It is important to note that some pearl cannot be measured. This is the case with baroque pearls.
