你對珍珠了解多少？

天然珍珠是在刺激物（通常是寄生蟲）進入牡蠣、貽貝或蛤蜊內部時形成的。作為回應，軟體動物會分泌一種稱為珠母層的液體，該液體會逐層覆蓋刺激物，從而形成珍珠。原產於印度洋和太平洋的 Pinctada maxima 牡蠣是最大的產珍珠牡蠣，它產出南海珍珠，是世界上最大的珍珠。養殖珍珠是透過人為干預創造的。這涉及將刺激物引入軟體動物以刺激珍珠生產過程。珍珠自然會出現多種顏色，包括白色、黑色、灰色、粉紅色和藍色。珍珠的顏色會受到軟體動物的種類以及其生長的水域條件的影響。中國是世界上最大的淡水養殖珍珠生產國。由於珍珠養殖技術的進步，該國已能夠大量生產珍珠。「巴洛克」是用於描述形狀不規則或非球形的珍珠的術語。這些形狀的範圍可以從輕微的偏差到明顯的卵形、彎曲、捏合或塊狀形狀。根據傳說，克麗奧佩特拉將一顆珍珠溶解在醋中並喝掉，以向馬克·安東尼證明她可以舉辦有史以來最昂貴的餐點。大溪地珍珠在法屬波利尼西亞生長，以其獨特的深色而聞名。雖然被稱為“黑珍珠”，但它們也有灰色、藍色、綠色和紫色的色調。珍珠的品質取決於多個因素，包括其大小、顏色、光澤（表面品質）和形狀。其他因素，如珠層厚度和表面缺陷的有無，也會被考慮在內。珠母貝是軟體動物外殼的彩虹色內層。它與覆蓋刺激物以在軟體動物內形成珍珠的材料相同。它經常被用於珠寶和裝飾。種珠是小而圓的珍珠，通常直徑小於 2 毫米。它們在維多利亞時代的珠寶中非常流行，現在經常被用於複雜、精緻的設計中。珍珠的形成時間長短不一，取決於珍珠的類型，但通常需要幾個月到幾年的時間。例如，南海珍珠可能需要 2 到 3 年才能完全形成。霍普珍珠是有史以來發現的最大的鹹水珍珠。它有鴿子蛋大小，價值約 35 萬美元。Mabe 珍珠，也稱為半邊珍珠，是專門培養在牡蠣殼內側生長的半珍珠，而不是在其身體組織內生長。術語“orient”用於指珍珠的光澤。這種虹彩是由於光線穿過珍珠的層狀珠母層時的干涉和衍射引起的。You scored 0 out of 15You scored 1 out of 15You scored 2 out of 15You scored 3 out of 15You scored 4 out of 15You scored 5 out of 15You scored 6 out of 15You scored 7 out of 15You scored 8 out of 15You scored 9 out of 15You scored 10 out of 15You scored 11 out of 15You scored 12 out of 15You scored 13 out of 15You scored 14 out of 15You scored 15 out of 15
