Description

Red Coral Stone – Coral gems are composed of calcium carbonate, which is believed to be beneficial to bones. Coral stones are bred from biological shrubs called polyps in the sea. Red coral stones are basically made from the bones of these polyps. The characteristic of this stone is that its delicate red or white color facilitates its use in jewelry. Coral stone is a fragile gem; its hardness is only 3.5 on the hardness scale. Therefore, this stone must be well maintained, otherwise it will be easily damaged.
