THE TONE OF CORAL

The colors of coral cover a wide range, including dark reds, orange reds (momo), and pinks, each color with its own character. The main gathering areas are the Mediterranean Sea for reds, the East China Sea for momo, and the ocean depths around Midway Island in the Pacific Ocean for pinks. Whether you like reds or pinks, tone is a matter of personal preference. The coral used in the “Rose de Noël” probably came from the East China Sea. It is of gem quality, with a tone level of 1. Coral is the product of natural activity, so just as with mineral gemstones, no two are exactly the same. High-quality pieces are those with an overall balance and beauty.

The hardness of coral is a low 31/2, and it is damaged by acids such as lemon juice or vinegar. The secret to preserving its beauty is to wipe it with a soft cloth after each use, and to keep it in a jewelry box, separate from other pieces.
