珊瑚长期以来一直广泛用于珠宝设计和其他装饰目的。 这种流行很大程度上归因于宝石的绚丽色彩及其原产地的不同寻常的性质。 珊瑚发现于地中海相对较浅且温暖的水域以及日本和台湾沿海。 它必须手动采摘，潜水员潜入很深的地方才能取回这种宝石。 在表面上，珊瑚标本根据大小、颜色和质量进行分类。 较大的无瑕标本非常罕见且相当昂贵。 因此，它们被用于高端珠宝设计，在公开市场上售价很高。 剩余的收获物用于时尚珠宝应用。 这些珊瑚片通常很软，必须用环氧树脂稳定以使其硬化，然后才能切割、抛光并镶嵌在银或其他金属中以完成珊瑚片。 有时，会在环氧树脂中添加染料以增强样品的颜色。 珊瑚有多种颜色。 然而，时尚珠宝应用中通常仅使用红色、粉色、橙色和黑色珊瑚。 黑珊瑚非常有价值，是从墨西哥海岸收获的。 近年来，潜水员一直无法找到大量的黑珊瑚，这导致环保主义者对某些珊瑚物种的破坏和可能灭绝发出了警报。
为了理解这些问题，首先对珊瑚的形成有一个基本的了解是有用的。 珊瑚是由海息肉的骨骼残骸形成的，海息肉是一种生活在海洋中、以浮游生物为食的微小生物。 随着时间的推移，遗骸会钙化并添加到珊瑚礁中。 经过几十年的时间，珊瑚礁可以长到很大，单个茎的直径可以达到2英寸。 然而，珊瑚对环境条件也非常敏感，海水化学、光穿透和温度的变化会对珊瑚礁产生毁灭性影响。 用于珠宝和装饰用途的珊瑚过度采伐，加上环境条件的逐渐变化，导致世界各地的珊瑚礁萎缩，一些物种几乎灭绝。 尽管一些国家承诺限制某些珊瑚品种的捕捞和贸易，但金融财富的诱惑意味着执法不严。 这颗宝石的美丽是否也会导致它的衰落，还有待观察。
