Are black pearls really black?
Just so, where do black pearls come from?
The Tahitian pearl (or black pearl) is an organic gem formed from the black lip oyster (Pinctada margaritifera). These pearls derive their name from the fact that they are primarily cultivated around the islands of French Polynesia, around Tahiti.
One may also ask, how can you tell if pearls are dyed? Jewellers and gemmologists assessing a pearl for treatment can identify a dyed pearl by looking down a drill hole to see the concentration of colour near the surface or the concentration of dye in the cracks. Sometimes the pearls are dyed on the strand and the strand may also take the colour of the dye.
Beside above, how can you tell if a black Tahitian pearl is real?
The Tooth Test: To find out if a pearl is real, lightly rub it against the front of your tooth — not against the edge, which can scratch the pearl. If natural or cultured, rather than simulated, the pearl should feel gritty.
Is a pearl rare?
The most valuable pearls occur spontaneously in the wild, but are extremely rare. These wild pearls are referred to as natural pearls. Cultured or farmed pearls from pearl oysters and freshwater mussels make up the majority of those currently sold.
