Also known as 'red coral' or 'tiger coral', apple coral that has been sealed and polished is usually a deep reddish color. When the apple coral is exposed to heat or intense sunlight for long periods, its striking color tends to lighten.
The destruction of coral reefs around the world led to a global ban on coral mining and collecting in 1992, but apple coral was not included, making it the only coral used by William Henry, aside from 100,000 year-old fossil brain coral which is also featured in our collections.
