At Jewel Beetle, we're great fans of both Black Pearls and our very own New Zealand Blue Pearls. In this blog, we've compiled some interesting information about Black pearls - nature's beautiful creation.
Unlike most other gemstones which are minerals, pearls are organic and are formed by living marine organisms. This natural occurrence happens when an oyster or mussel receives an irritant inside its shell. To protect itself, the mollusc deposits layers of ‘nacre’ over the irritant. Just like the shell, the ‘nacre’ is made up of calcium carbonate. This iridescent coating is what makes these gems so beautiful. These layers build up over time and this is how the pearl is formed.
