How Tahitian pearl gets cultured?
The black lipped oyster species called Pinctada Margaritifera is found in French Polynesia, Sea of Cortez, and Cook Islands. To cultivate a good quality black pearl takes lot of hard work and time.
One pearl is grown in each oyster and it takes around 2 to 3 years for the nucleation to age. The growth phase of pearl is around 16 months to two years. The pearl farmers nurture the oysters well, during this growth period. They make sure that the water temperature is precise and the oysters get enough nutrients.
Just 40% nucleated oysters produce selling quality pearls. Out of which only 2% are near to round shaped with finest quality. Majority of black pearls are baroque or circle shaped. The luster ranges from excellent to fair. Reflection is sharp and bright to almost metallic shine.
All the black exotic pearls available are cultured. It is a fact that human effort made is 30%, whereas the rest is left to nature. Therefore, pearl is considered to be a very fascinating gem. It is an organic gemstone that ground us to earth and nature.
Tahitian pearls surface quality can range from flawless to heavily blemish. Majority of heavy spots can be concealed with a drill hole. Nacre thickness [often 2mm around bead nuclei] is acceptable in these pearls. You will hardly find black pearls with chalky appearance.
French Polynesia government has set minimum nacre thickness around 0.8mm, so any pearl with less is not permitted for selling. It is a good guideline to use while buying Tahitian pearls.
