珊瑚長期以來一直廣泛用於珠寶設計和其他裝飾目的。 這種流行很大程度上歸因於寶石的絢麗色彩及其原產地的不同尋常的性質。 珊瑚發現於地中海相對較淺且溫暖的水域以及日本和台灣沿海。 它必須手動採摘，潛水員潛入很深的地方才能取回這種寶石。 在表面上，珊瑚標本根據大小、顏色和品質進行分類。 較大的無瑕標本非常罕見且相當昂貴。 因此，它們被用於高端珠寶設計，在公開市場上售價很高。 剩餘的收穫物用於時尚珠寶應用。 這些珊瑚片通常很軟，必須用環氧樹脂穩定以使其硬化，然後才能切割、拋光並鑲嵌在銀或其他金屬中以完成珊瑚片。 有時，會在環氧樹脂中添加染料以增強樣品的顏色。 珊瑚有多種顏色。 然而，時尚珠寶應用中通常僅使用紅色、粉紅色、橙色和黑色珊瑚。 黑珊瑚非常有價值，是從墨西哥海岸收穫的。 近年來，潛水員一直無法找到大量的黑珊瑚，這導致環保人士對某些珊瑚物種的破壞和可能滅絕發出了警報。
為了理解這些問題，首先對珊瑚的形成有基本的了解是有用的。 珊瑚是由海息肉的骨骼殘骸形成的，海息肉是一種生活在海洋中、以浮游生物為食的微小生物。 隨著時間的推移，遺骸會鈣化並添加到珊瑚礁中。 經過幾十年的時間，珊瑚礁可以長到很大，單一莖的直徑可以達到2英吋。 然而，珊瑚對環境條件也非常敏感，海水化學、光穿透和溫度的變化會對珊瑚礁產生毀滅性影響。 用於珠寶和裝飾用途的珊瑚過度採伐，加上環境條件的逐漸變化，導致世界各地的珊瑚礁萎縮，有些物種幾乎滅絕。 儘管一些國家承諾限制某些珊瑚品種的捕撈和貿易，但金融財富的誘惑意味著執法不嚴。 這顆寶石的美麗是否也會導致它的衰落，還有待觀察。
