黃色寶石：您能否鑑定這些寶石？

Sunshine, lemons, and yellow flowers evoke happiness, warmth, and optimism. Similarly, yellow gemstones—from diamonds and citrines to garnets—radiate a captivating glow.
陽光、檸檬，還有各種黃色的花朵，總讓人感到幸福、溫暖和樂觀。從鑽石、黃水晶到柘榴石，許多寶石也呈現黃色色彩。

Yellow diamonds are durable and hold long-term value, often used in fine jewelry. However, beyond yellow diamonds, there are many other affordable yellow gemstones, ranging from pale lemon to rich golden hues.
黃色鑽石堅固耐磨、價值持久，經常用於珠寶鑲嵌。不過，除了黃色鑽石之外，還有很多其他價格相對實惠的黃色寶石。這些寶石的顏色從淡黃色色彩到濃郁的暖色不等。

The most common yellow gemstones include citrine, sapphire, topaz, tourmaline, and transparent opal. Others include andradite and spessartine garnets, Mali garnet, beryl, sphene, zircon, spodumene, and certain feldspars. Rare or collectible varieties include chrysoberyl, sphalerite, apatite, and prehnite.
市面上最常見的黃色寶石是黃水晶、藍寶石、拓帕石、碧璽和透明蛋白石。其他黃色寶石包括黃色鈣鐵榴石、錳鋁榴石、馬里柘榴石、綠柱石、榍石、鋯石、鋰輝石和各種透明的鈉長石與正長石。較不常見或有收藏價值的黃色寶石包括金綠玉、閃鋅礦、磷灰石和葡萄石。

Yellow Diamonds: The Classic Choice

黃色鑽石：經典之選

Among natural fancy-color diamonds, yellow is the most common—yet still rare overall. The first major source was discovered in the 1860s in South Africa’s Cape Province, hence the trade term “Cape diamonds.”
天然彩鑽中，黃色鑽石是最多的，但黃色鑽石也僅佔所有鑽石的極小部分。19世紀60年代，南非開普省發現了第一個黃色鑽石的主要產地。因此在珠寶行業中，這些黃色鑽石也被稱為「開普」黃色鑽石。

Per the GIA Diamond Dictionary, a Cape diamond is a Type Ia stone with distinct yellow body color and specific absorption bands (notably at 415.5 nm and 478.0 nm). It may also display blue, yellow, or orange fluorescence.
根據《GIA鑽石辭典》，「開普」鑽石是一種呈現明顯黃色體色的Ia型鑽石，呈現出特定、明確的吸收帶（通常在415.5 nm處為強吸收帶，478.0 nm處為較強吸收帶）。這種鑽石可能也會呈現藍色、黃色或橙色熒光。

What causes the yellow color?
鑽石呈現黃色的原因是什麼？

GIA diamond color expert John King explains: “Essentially, nitrogen atoms in diamond cause absorption in the blue region of the visible spectrum; the remaining light transmitted results in perceived yellow color.”
GIA鑽石顏色專家John King解釋說：「大體而言，鑽石中的氮原子引起可見光譜藍色區域的吸收；光譜其餘部分被透射，產生可見黃色。」

Historically, intensely saturated Type Ib yellow diamonds were called “canary diamonds” to distinguish them from Cape-type stones. “Canary” diamonds are prized for their vibrant, saturated yellow hue.
Ib型濃彩黃色鑽石的歷史術語是「金絲雀」，用以區別帶有「開普」光譜的鑽石。業內稱為「金絲雀黃」的鑽石，因其濃郁飽和的黃色而備受推崇。

Diamonds possess an undeniable allure. As early as 1676, French traveler and gem merchant Jean-Baptiste Tavernier recorded a 137.27-carat yellow diamond—later referenced under names like Florentine and Austrian Yellow. Since then, especially with growing appreciation for color, many famous colored diamonds have gained legendary status.
鑽石有一種難以言喻的魅力，深深吸引著寶石愛好者。早在1676年，法國旅行家、寶石商人Jean-Baptiste Tavernier就曾記載他看到一顆重137.27克拉的黃色鑽石，並多次以Florentine、Austrian Yellow等不同名字提及這顆鑽石。從那之後，尤其是隨著人們日益重視鑽石顏色，許多著名彩色鑽石都列為上乘精品。

Tiffany & Co. purchased the Tiffany Yellow Diamond in 1878, displaying it in their New York flagship store for over 70 years. Cut from a 297.42-carat rough under Dr. George Frederick Kunz’s direction, it is now a 128.54-carat cushion-cut stone—one of the world’s largest fancy yellow diamonds. GIA graded it in 1984.
1878年，蒂芙尼公司買下了Tiffany Yellow Diamond。之後70多年，這顆鑽石一直在其紐約的旗艦店展出。在George Frederick Kunz博士的指導下，這顆鑽石從重達297.42克拉的原石，切磨為現在這顆重128.54克拉的墊形切工鑽石，是世界最大的彩黃色鑽石之一。1984年，GIA對這顆鑽石進行了分級。

The Allnatt Diamond—named after former owner Major Alfred Ernest Allnatt—is believed to originate from De Beers’ South African mines. It appeared at Christie’s Geneva in May 1996 weighing 102.07 carats as Fancy Intense yellow. After being acquired, it was recut to 101.29 carats to optimize color (now Fancy Vivid) and clarity (VS2). The Allnatt exemplifies early 20th-century cutting styles that maximized weight retention from octahedral rough.
Allnatt以其前主人Major Alfred Ernest Allnatt的名字命名，有人認為這顆鑽石可能源自戴比爾斯南非礦區。這顆鑽石後來出現在1996年5月的佳士得日內瓦拍賣會上，重102.07克拉，顏色級別為濃彩黃。這顆鑽石被買下後，重新切磨成101.29克拉的鑽石以優化顏色和淨度，從濃彩級變為艷彩級，淨度提升至VS2級。Allnatt是採用20世紀早期切磨式樣、以最大限度保留形態完整的八面體原石晶體重量並提升其顏色的典型案例。

In 1972, logger George Stepp found a yellow diamond crystal at Arkansas’s Crater of Diamonds State Park, selling it to Kahn Jewelers of Pine Bluff. Instead of cutting it, they preserved its natural triangular cushion shape (“macle”). The Kahn Canary Diamond weighs 4.25 carats and is internally flawless.
1972年，阿肯色州迦太基的伐木工George Stepp在阿肯色州Crater of Diamonds State Park發現一顆黃色鑽石晶體，並將其賣給阿肯色州派恩布拉夫Kahn Jewelers。Kahn Jewelers並未切磨這顆鑽石晶體，而是保留了這顆鑽石天然的三角枕形形狀（「孿晶」）。「Kahn Canary Diamond」重4.25克拉，是內無瑕級鑽石。

Since the park became a public state park in 1977, over 33,000 diamonds have been found there. It operates on a “finders-keepers” policy, allowing paid public digging.
自Crater of Diamonds State Park於1977年成為州立公園並對外開放後，這裡發現了33,000多顆鑽石。該公園遵循「發現者即所有者」的政策，公眾可付費挖掘鑽石。
