It's simple. Currently, the probability of finding a natural pearl in the wild is approximately 1:1,000,000. They are worth on average $300-$1500 for a single pearl and within a few years, that probability will drop to Zero. Cultured pearls will see no significant increase in value. Contrary to cultured pearls, NATURAL PEARLS will go extinct and will be valued as relics. The increase in the value of a NATURAL pearl within 3 - 10 years will be of a similar magnitude to that of buying a bitcoin in it's founding year. As time passes, they will only go up in value.
