They grow in the Black lipped oyster which produces black pigment and are found in the surrounding area of the archipelago of French Polynesia, Panama and Mexico.
Tahitian pearls are mainly 8-18mm in diameter although they can grow to 21mm.
Their colours are naturally dark and range from grey to black and peacock green to aubergine; however, they can sometimes be very light in colour from white to yellow and pink all of which have grey overtones.
Always choose the pearls with the deepest lustre within the budget set, if necessary compromising on size and surface perfection, as it is the lustre which will light up the wearer’s face and will therefore be most flattering. All the pearls we use in Coleman Douglas Pearls jewellery are individually chosen for their lustre.
The nacre thickness of a cultured Tahitian pearl starts at .9mm and usually has a 2.5mm nacre thickness.The thicker the nacre is, the longer the pearls will last, and usually the better their lustre will be.
