三月的誕生石是海藍寶石。大約2千年前，羅馬人將這種淺藍色的寶石命名為Aquamarine，這個名字來自於拉丁文 "aqua"，意思是『水 water』、『小游艇船塢 marina』和『海 sea』。海藍寶石被認為可以保護水手，並且保證有一次安全的遠航。
海藍寶石平靜的顏色被認為可以平息怒氣、冷靜情緒，令穿戴者保留鎮靜和讓頭腦清醒。它的顏色最好是較淡的顏色，最常在春夏時佩帶。在光線下，海藍寶石的顏色範圍是由greenish blue 到 blue-green。較大的寶石上的顏色是比較強烈的。
由於使用較低定價的藍色黃玉blue topaz作代替品，海藍寶石在美國的銷售是最差的。海藍寶石主要在巴西開採，但尼日利亞、馬達加斯加、贊比亞、巴基斯坦和莫桑比克都有開採。在其他地方，海藍寶石的需求依然沒有減少。在海外國家，消費者尋找持久的價值和欣賞。海藍寶石在幾十年間保持到它的價值，令它成為一種明智的投資和強大的財產。
The birthstone of March is aquamarine. Named by the Romans about 2,000 years ago, its name is derived from the Latin word aqua, meaning "water," and marina, meaning "sea". This stone was known to protect sailors, as well as guarantee a safe voyage.
The serene color of aquamarine is known to cool the temper, allowing the wearer to remain calm and levelheaded. Its color suggests coolness and often is worn in spring and summer. Colors range from greenish blue to blue-green in light tones. The color is usually more intense in larger stones.
Aquamarine's sales have been weakest in the United States due to the use of blue topaz as a lower priced substitute. It is found mainly in Brazil, and also in Nigeria, Madagascar, Zambia, Pakistan and Mozambique. Elsewhere in the world, the demand for this stone has not faltered. In countries abroad, consumers are looking for lasting value and long-term appreciation. Aquamarine has held its value throughout decades, making it a wise investment and a strong asset.
