White opal is the most common opal colorTake one look at any opal and you’ll find a world of colors illuminating from the gem. Opals are renowned for an optical feature called “play-of-color,” which describes the way color dances across the stone. No opal stone displays just one color, so what is the most common opal? To answer that, we have to look at the body color (body tone) of the gem. Based on body tone, white opal is the most common opal color, followed by gray opal and green opal. 

If you hear “common” and think “ordinary,” we’d like to ask you to think again! You could call this gem a master of disguise for the array of opal colors out there. Opal can’t be concealed though; its glimmer and enchanting play-of-color are sure to catch anyone’s eye! 

Speaking of eyes, one theory of opal’s etymology is from the Greek word for eyes, ophthalmos. Another possible source is the Sanskrit word Uppal, which means “precious milky stone.” 

October babies might recognize the gorgeous milky opal as the traditional October birthstone. If you were born in April, you can honor the ancient mystical birthstones with some gorgeous opal jewelry of your own.

No matter who flaunts it, opal is an enchanting gem with lots of charm. To fully understand the most common opal color, we’ll need to dive into the different types of opals and where they come from.

First, let’s go over the basics.

Opal colors

What is an Opal Stone?

Opal is a mineraloid composed of silicon dioxide and varying amounts of water. Unlike most gemstones, opal doesn’t have a crystal structure or consistent chemical composition, making it amorphous.

Opal belongs to its own gemstone family, the opal family. Opal gems get their trademark pearly sheen from their internal structure, made up of tightly packed spheres that split up the light into multiple colors.

So, what color is opal?

You may associate opal with colorful iridescence, reminiscent of the rainbows on soap bubbles. However, iridescence is specific to precious opal.

Precious opal, or noble opal, is a variety that displays play-of-color. In other words, turning the stone under the light will cause the gem to shine in an array of colors. The colors will change depending on the angle you view the gem. 

Precious opal colors vary from stone to stone. Some precious opal stones may have a dark base, such as black or royal blue. Others could have a white body tone. Some precious opals show so many different colors, the base color is indiscernible.

Precious opal often gets confused with the variety called “common opal,” which we’ll explore in greater detail next.

Common Opal

What is a Common Opal?

Common opal, or “potch,” is the most abundant variety of opal worldwide. The gem comes in a wide array of colors and most opal varieties fall under the “common opal” umbrella. How can you identify common opal? If the stone doesn’t exhibit play-of-color, then it’s good ol’ fashioned common opal.

Another signature trait of common opal is opalescence. Opalescence is an optical effect that describes common opal’s milky, internal glow. While the play-of-color effect makes a gem’s surface reflect light, opalescence looks like a hazy light coming from inside the stone.

Common opal can show almost any color, and its pastel hues are adored by many. Most often, common opal has a white or blue body tone. 

What is the rarest opal color? The rarest opal specimens have a red or black body tone.

A black body tone is great for displaying another fascinating opal trait: fluorescence.

Have you ever cracked a glow stick? That green glow you see afterward is because of fluorescence. Opal can show fluorescence weakly or strongly, even in the same green color of a glow stick. An opal can also fluoresce in yellowish-green, light blue, greenish-brown, or white. 

The cause of opal’s fluorescence is most likely hints of uranium inside the gem. More uranium can cause stronger fluorescence. Some fluorescent opals from Nevada have 0.12% uranium by weight!

We know where opal’s fluorescence comes from, but what about its color?

Play of color

What Causes Opal Color?

Common and precious opal form in mostly the same environments: deep within rocks in areas with an arid climate. Miners may have to dig 60 feet underground to find opal worth selling. Why so deep? Well, opal formation happens over millions of years. 

First, hot water soaks into the ground. As it flows down into the earth, the water collects silica spheres. Eventually, the silica-rich water settles into pockets in the rock. The silica spheres get packed together as the water evaporates, leaving behind colorful opal.

Where does opal color come in? It all goes back to the silica spheres.

The silica spheres in opal are technically silicon dioxide crystals. When the spheres are around the same size and packed in neatly arranged stacks, we see play-of-color. Isn’t nature amazing? The size of each sphere determines which color of light that area reflects.

If you’ve been following along, you might’ve realized that only precious opals have tightly packed spheres. If so, A+ to you!

Common opal’s silica spheres are disorganized and vary a lot in size. Therefore, common opal cannot reflect the spectrum of light that precious opal can. Instead, common opal can only display a limited color range, determined by the size and distance between its spheres.

On the topic of distance, how does hunting for opals sound? Next, we’ll break down all the opal hotspots worldwide so you can plan your next opal odyssey!

Opal Colors By Locality

Although opal can be found in various rocks and locations, specific environments produce different opal colors. Some locations are known for their opal varieties. 

One town called Coober Pedy in South Australia is known as the “opal capital of the world.” Australia is so renowned for its opals, opal is the country’s national gem!

Australia

Australia boasts some of the most abundant opal deposits in the world. In fact, at least 90% of the world’s opals come from Australia!

Each opal-producing state in Australia has an opal color specialty.

In the fields of Western Australia, pink opal is common. “pink opal” is actually a trade name for Mookaite with opal attached to it. However, opaline Mookaite can show patterns in shades of cream, yellow, and red.

Another opaline stone is the boulder opal

Found in Queensland, boulder opal is a combination of opal and ironstone. Each boulder opal has unique coloring and patterns. In general, boulder opal is brown with a scattering of luminescent purples, blues, or greens. 

The exclusive black opal color is the specialty of New South Wales. 

Black opal is incredibly hard to come by. The lucky few who can get a black opal might get lost in its mesmerizing brilliance and color patterns.

Lastly, South Australia specializes in light opal. Light opal is typically white or cream, giving the stone the nickname “white opal” or “milky opal.”

Africa

Ethiopia and Kenya have made quite a splash in the opal market. 

Australia is the king of opals, but Ethiopia has been competing for the crown

Ethiopian opals are mostly white and cream precious opals. In recent years, the coveted black opal color has shown up in Ethiopian deposits as well.

The Ethiopian Welo opal is another stunning local variety. Named after the Wollo Province, Welo opal is a precious fire opal with red, orange, and yellow body colors. Welo opals can display vibrant green or purple color flashes.

Kenya plays a significant role in opal’s history as the location of the oldest opals ever discovered. In modern times, common opal is Kenya’s most abundant variety. What color are they? Kenya’s opal colors consist of beautiful shades of olive green.

South America

Over in South America, Peru and Brazil are the continent’s key opal suppliers.

If you’re a fan of the pastel color palette, you’ll love Peru’s opal collection. Peruvian opals come in an array of soft pastels, particularly pink, blue, and green. 

Brazilian opal is unique in its durability and brilliance. Brazil’s crystal opal displays play-of-color in mystical pastel tones. The low amount of water in these gems gives them better durability, so jewelers can bring out the best opal colors with a variety of faceting techniques.

Mexico

Mexico takes pride in two unique opal colors: the Mexican fire opal and the Morado opal.

While many opals are translucent to opaque, Mexican opal colors display a transparent to translucent surface. 

Mexican fire opal color is, perhaps unsurprisingly, similar to fire. The gem can be yellow, white, orange, or red. Like a burning flame, the best specimens have a saturated red-orange color.

The Morado opal is a purple opal color variety. Morado means “purple” in Spanish, hence its moniker. These opals are typically opaque with a milky lavender and violet color pattern.

United States

American opal mines are spread throughout the country, but two notable states for opal production are Oregon and Nevada.

  • Oregon. Oregon has two significant opal mines: one in an area aptly named Opal Butte and one in Lake County. Oregon’s opals mostly consist of pink, yellow, and blue shades.

    The volcanic ashfall in the state creates a great environment for opalized wood to occur. Opalized wood is petrified wood that contains opal inside instead of the more common chalcedony.

    Opalized wood forms when ashfall creates a protective forest layer, allowing for the ash’s dissolved silica to seep into the ground. From there, groundwater sources can collect the silica and begin the usual opal formation process.

  • Nevada. The locals of Virgin Valley, Nevada, claim that opal started forming there millions of years ago. Opalized fossils may give this theory some weight, but no one can be certain when the opal formed onto the fossils.

    Regardless, Virgin Valley opals emerge from wet clay beds in spectacular colors. Nevada’s opals include black opal and precious black opal, for starters. Other opals mined include white and yellow opals, plus opals with moss or dendrite inclusions.

    The area’s high uranium levels give many opals high fluorescence. Under an ultraviolet lamp (or blacklight) these opals glow bright, electric green.

With all the opal color options out there, you might wonder: What are the best opals to buy?

How Color Affects Opal Value

Determining an opal’s value isn’t a simple process. Numerous factors affect an opal’s overall value, from where it was mined to what shape it takes, and of course, its unique color properties.

Generally speaking though, the most valuable opals are the rarest varieties and the least valuable opals are the most common.

So, what color opal is most valuable?

Black opals tend to be the rarest variety of opal, with precious black opal being even harder to find. However, the highest-valued opal color is the rare red opal. Orange, green, blue, and purple opals are next in line in terms of value.

If you’re curious, the most expensive opal in the world is The Virgin Rainbow (pictured below). Discovered in 2003, The Virgin Rainbow’s value exceeds $1 million. The impressive specimen is currently on display in the South Australian Museum.

白蛋白石是最常見的蛋白石顏色看一看任何蛋白石,您會發現寶石散發出的色彩世界。蛋白石以一種稱為“遊彩”的光學特徵而聞名,它描述了顏色在石頭上跳舞的方式。沒有蛋白石只顯示一種顏色,那麼最常見的蛋白石是什麼?要回答這個問題,我們必須查看寶石的體色(體色)。根據體色, 白蛋白石是最常見的蛋白石顏色,其次是灰色蛋白石和綠色蛋白石。

如果您聽到“普通”並認為“普通”,我們想請您再想一想!您可以稱這顆寶石為各種蛋白石顏色的偽裝大師。但是蛋白石無法隱藏;它的微光和迷人的遊彩一定會吸引任何人的眼球!

說到眼睛,蛋白石詞源的一種理論來自希臘語單詞ophthalmos 。另一個可能的來源是梵文單詞Uppal ,意思是“珍貴的乳白色的石頭”。

十月寶寶可能會認出華麗的乳白色蛋白石是傳統的十月生日石。如果您出生在四月,您可以用自己的一些華麗的蛋白石首飾來紀念古老的神秘誕生石。

無論誰炫耀它,蛋白石都是一種迷人的寶石,具有很多魅力。要充分了解最常見的蛋白石顏色,我們需要深入了解不同類型的蛋白石及其來源。

首先,讓我們回顧一下基礎知識。

蛋白石顏色

什麼是蛋白石?

蛋白石是由二氧化矽和不同量的水組成的礦物。與大多數寶石不同,蛋白石沒有晶體結構或一致的化學成分,因此是無定形的。

蛋白石屬於自己的寶石家族——蛋白石家族。蛋白石寶石從其內部結構中獲得其標誌性的珍珠光澤,由緊密排列的球體組成,將光線分成多種顏色。

那麼,歐泊是什麼顏色?

您可能會將蛋白石與五顏六色的彩虹色聯繫起來,讓人聯想到肥皂泡上的彩虹。然而,彩虹色是珍貴 蛋白石所特有的。

珍貴蛋白石或高貴蛋白石是一種顯示遊彩的品種。換句話說,在光線下轉動寶石會使寶石發出一系列顏色的光芒。顏色會根據您查看寶石的角度而變化。

珍貴的蛋白石顏色因石頭而異。一些珍貴的蛋白石可能具有深色底色,例如黑色或寶藍色。其他人可能有白色的身體色調。一些珍貴的蛋白石呈現出如此多的不同顏色,基色難以辨認。

珍貴的蛋白石經常與被稱為“普通蛋白石”的品種混淆,我們將在接下來更詳細地探討。

普通蛋白石

什麼是普通蛋白石?

普通蛋白石或“potch ”是世界上最豐富的蛋白石品種。這種寶石有多種顏色,大多數蛋白石品種都屬於“普通蛋白石”保護傘。如何識別普通蛋白石?如果石頭沒有出現遊彩,那麼它就是很好的老式普通蛋白石。

普通蛋白石的另一個標誌性特徵是乳光。乳光是一種光學效應,描述了普通蛋白石的乳白色內部發光。雖然遊彩效果使寶石表面反射光線,但乳光看起來像是從寶石內部發出的朦朧光線。

普通蛋白石幾乎可以顯示任何顏色,其柔和的色調受到許多人的喜愛。大多數情況下,普通蛋白石具有白色或藍色的體色。

什麼是最稀有的蛋白石顏色?最稀有的蛋白石標本具有紅色或黑色的體色。

黑色的身體色調非常適合展示另一個迷人的蛋白石特性:熒光。

你有沒有破解過熒光棒?之後您看到的那種綠光是因為熒光。蛋白石可以顯示出弱或強的熒光,即使是熒光棒的相同綠色。蛋白石也可以發出黃綠色、淺藍色、綠褐色或白色的熒光。

蛋白石發出熒光的原因很可能是寶石內部含有鈾的跡象。更多的鈾會導致更強的熒光。一些來自內華達州的熒光蛋白石含有0.12% 的鈾重量!

我們知道蛋白石的熒光來自哪裡,但它的顏色呢?

玩顏色

什麼導致蛋白石顏色?

常見且珍貴的蛋白石在幾乎相同的環境中形成:在乾旱氣候地區的岩石深處。礦工可能需要在地下挖 60 英尺才能找到值得出售的蛋白石。為什麼這麼深?嗯,蛋白石的形成經歷了數百萬年。

首先,熱水浸入地下。當它向下流入地球時,水會收集二氧化矽球體。最終,富含二氧化矽的水沉澱在岩石中的口袋中。隨著水的蒸發,二氧化矽球體會聚集在一起,留下五顏六色的蛋白石。

蛋白石顏色從何而來?這一切都可以追溯到二氧化矽球體。

蛋白石中的二氧化矽球體在技術上是二氧化矽晶體。當球體大小相同並排列整齊時,我們會看到遊彩。大自然是不是很神奇?每個球體的大小決定了該區域反射的光的顏色。

如果您一直在關注,您可能已經意識到只有珍貴的蛋白石才有緊密堆積的球體。如果是這樣,給你A+!

普通蛋白石的二氧化矽球體雜亂無章,大小差異很大。因此,普通蛋白石不能像珍貴蛋白石那樣反射光譜。相反,普通蛋白石只能顯示有限的顏色範圍,這取決於其球體之間的大小和距離。

關於距離的話題,尋找蛋白石聽起來如何?接下來,我們將分解全球所有蛋白石熱點,以便您計劃下一次蛋白石奧德賽!

不同地區的蛋白石顏色

雖然蛋白石可以在不同的岩石和地點找到,但特定的環境會產生不同的蛋白石顏色。有些地方以其蛋白石品種而聞名。

南澳大利亞的一個名為 Coober Pedy 的小鎮被稱為“世界蛋白石之都” 。澳大利亞以其蛋白石而聞名,蛋白石是該國的國寶!

澳大利亞

澳大利亞擁有世界上最豐富的蛋白石礦床。事實上, 世界上至少 90%的蛋白石來自澳大利亞!

澳大利亞的每個蛋白石生產州都有蛋白石顏色特產。

在西澳大利亞的田野中,粉紅蛋白石很常見。 “粉紅蛋白石”實際上是附有蛋白石的穆凱石的商品名。然而,乳白色穆凱石可以顯示奶油色、黃色和紅色色調的圖案。

另一種蛋白石是巨石蛋白石

在昆士蘭發現的巨石蛋白石是蛋白石和鐵石的組合。每顆巨石蛋白石都有獨特的顏色和圖案。一般來說,巨石蛋白石是棕色的,散佈著發光的紫色、藍色或綠色。

獨特的黑蛋白石顏色是新南威爾士州的特產。

黑蛋白石非常難以獲得。少數能夠獲得黑色蛋白石的幸運兒可能會迷失在其迷人的光彩和色彩圖案中。

最後,南澳大利亞專門生產輕蛋白石。輕蛋白石通常是白色或奶油色,因此人們給這種石頭起了“白蛋白石”或“乳蛋白石”的綽號。

澳大利亞黑蛋白石澳大利亞黑蛋白石

非洲

埃塞俄比亞和肯尼亞在蛋白石市場上引起了不小的轟動。

澳大利亞是蛋白石之王,但埃塞俄比亞一直在爭奪王冠

埃塞俄比亞蛋白石大多是白色和奶油色的珍貴蛋白石。近年來,令人垂涎的黑蛋白石顏色也出現在埃塞俄比亞的礦床中。

埃塞俄比亞Welo 蛋白石是另一種令人驚嘆的當地品種。 Welo 蛋白石以 Wollo 省命名,是一種具有紅色、橙色和黃色體色的珍貴火蛋白石。 Welo 蛋白石可以顯示出充滿活力的綠色或紫色閃光。

肯尼亞作為有史以來發現的最古老的蛋白石的所在地,在蛋白石的歷史上扮演著重要的角色。在現代,普通蛋白石是肯尼亞最豐富的品種。它們是什麼顏色?肯尼亞的蛋白石顏色由美麗的橄欖綠色調組成。

南美洲

在南美洲,秘魯和巴西是該大陸的主要蛋白石供應商。

如果您喜歡柔和的調色板,那麼您一定會喜歡秘魯的蛋白石系列。秘魯蛋白石有一系列柔和的粉彩,尤其是粉紅色、藍色和綠色。

巴西蛋白石的耐用性和亮度是獨一無二的。巴西的水晶蛋白石以神秘的柔和色調呈現遊彩。這些寶石中的少量水使它們具有更好的耐用性,因此珠寶商可以通過各種切面技術呈現最好的蛋白石顏色。

巴西蛋白石巴西蛋白石

墨西哥

墨西哥以兩種獨特的蛋白石顏色而自豪:墨西哥火蛋白石和莫拉多蛋白石。

雖然許多蛋白石是半透明到不透明的,但墨西哥蛋白石的顏色顯示出透明到半透明的表面。

毫不奇怪,墨西哥火蛋白石的顏色與火相似。寶石可以是黃色、白色、橙色或紅色。就像燃燒的火焰一樣,最好的標本具有飽和的紅橙色。

莫拉多蛋白石是一種紫色的蛋白石顏色品種。 Morado在西班牙語中意為“紫色”,因此得名。這些蛋白石通常是不透明的,帶有乳白色的薰衣草和紫羅蘭色圖案。

墨西哥火蛋白石墨西哥火蛋白石

美國

美國蛋白石礦遍布全國,但兩個著名的蛋白石生產州是俄勒岡州和內華達州。

  • 俄勒岡州。俄勒岡州有兩個重要的蛋白石礦:一個位於名為 Opal Butte 的地區,另一個位於萊克縣。俄勒岡州的蛋白石主要由粉紅色、黃色和藍色色調組成。

    該州的火山灰為乳白木的產生創造了良好的環境。蛋白石木是石化木,裡面含有蛋白石,而不是更常見的玉髓。

    當灰燼形成一個保護性森林層時,蛋白石木材就會形成,使灰燼中溶解的二氧化矽滲入地下。從那裡,地下水源可以收集二氧化矽並開始通常的蛋白石形成過程。

  • 內華達州。內華達州維爾京谷的當地人聲稱,蛋白石在數百萬年前開始在那裡形成。蛋白石化石可能會給這一理論帶來一定的影響,但沒有人能確定蛋白石是何時在化石上形成的。

    無論如何, 維爾京谷蛋白石從潮濕的粘土層中以壯觀的顏色出現。對於初學者來說,內華達州的蛋白石包括黑蛋白石和珍貴的黑蛋白石。其他開采的蛋白石包括白色和黃色蛋白石,以及帶有苔蘚或樹枝狀內含物的蛋白石。

    該地區的高鈾含量使許多蛋白石具有高熒光。在紫外線燈(或黑光)下,這些蛋白石發出明亮的電綠色。

美國蛋白石處女谷維爾京谷美國蛋白石

有了所有蛋白石顏色選項,您可能想知道:什麼是最好的蛋白石購買?

顏色如何影響蛋白石價值

確定蛋白石的價值並不是一個簡單的過程。許多因素都會影響蛋白石的整體價值,從它的開採地點到它的形狀,當然還有它獨特的顏色特性。

但一般來說,最有價值的蛋白石是最稀有的品種,而最不值錢的蛋白石是最常見的。

那麼,什麼顏色的蛋白石最有價值?

黑蛋白石往往是最稀有的蛋白石品種,珍貴的黑蛋白石更難找到。然而,價值最高的蛋白石顏色是罕見的紅色蛋白石。橙色、綠色、藍色和紫色蛋白石的價值緊隨其後。

如果您好奇,世界上最昂貴的蛋白石是維珍彩虹(如下圖)。 2003 年發現的處女彩虹價值超過 100 萬美元。這個令人印象深刻的標本目前在南澳大利亞博物館展出。
