epidote gemstoneEpidote is a commonly yellowish-green to green gemstone resembling the color of pistachios. Is epidote rare or common? As a mineral, epidote is common and abundant worldwide. However, the stone’s fragile nature makes faceted epidote gems rare. 

Besides being a gemstone itself, epidote is also a group of gems which includes stone like zoisite. You may also see epidote as inclusions in other stones.

On the lookout for epidote jewelry? Just want to know more about this lush stone? Stay tuned as we cover all of epidote’s properties, healing powers, prices, and more.

About Epidote Stone

Epidote is a semi-precious gemstone found in yellow to green, though it may appear brown or black because of how dark the tone can be.

At first glance, you may wonder: is epidote green tourmaline? No, green tourmaline (and tourmaline in general) is a separate stone. Though similar in color, green tourmaline doesn’t have epidote’s cleavage and epidote doesn’t have tourmaline’s triangular or hexagonal cross-section. 

Another common mix-up is epidote vs. olivine. Olivine (a.k.a. chrysolite or peridot) is a green magnesium iron silicate. The plainest distinction is that epidote is usually found within or around quartz while olivine is never found near quartz.

Luckily, epidote’s resemblance to peridot means it can also be a more affordable substitute for the traditional August birthstone. On its own, epidote is a zodiac stone for Gemini.

Outside of gemstone purposes, epidote doesn’t have any industrial uses. 

Next, what kind of stone is epidote?

Epidote Specifications & Characteristics

As a calcium aluminum iron sorosilicate, the epidote mineral formula is Ca2(Al,Fe)3(SiO4)3(OH). The stone belongs to the eponymous epidote mineral group and serves as the most common member. Other gems in this group include zoisite, clinozoisite, allanite, and piemontite.

Clinozoisite and epidote are extremely similar and virtually indistinguishable, so you may see sellers labeling these stones as “clinozoisite-epidote.” Some specimens are composed of both minerals.

The main crystal habit of epidote is column-shaped prisms with lengthwise faces. It often forms twinning crystals as well. 

How do you identify epidote? The easiest test is measuring the stone’s birefringence with a refractometer, since epidote has higher birefringence than most stones. 

Here are the remaining mineral data for epidote, including its birefringence values: 

  • Mohs hardness: 6-7

  • Color: Green, yellow-green, yellow, brown, blackish-green

  • Crystal structure: Monoclinic

  • Luster: Vitreous (glassy), pearly, resinous, or greasy

  • Transparency: Transparent to translucent, sometimes near opaque

  • Refractive index: 1.72-1.77

  • Density: 3.35-3.50

  • Cleavage: Perfect, 1-direction; Good, 1-direction

  • Fracture: Irregular/Uneven

  • Streak: Grayish-white

  • Luminescence: None

  • Pleochroism: Present and strong in yellow, green, and brown

  • Birefringence: 0.019-0.045

  • Dispersion: Strong; 0.030

Types of Epidote

Epidote has one somewhat official variety. There is another stone mostly made up of epidote along with a particular type of epidote displaying optical phenomena. These are:

  • Pistacite: Pistachio-green epidote variety occasionally faceted into small gems

  • Unakite: Polished rock largely composed of epidote and other minerals

  • Cat’s Eye Epidote: Epidote that contains parallel fibers that produce a single ray of reflected light through the optical effect of chatoyancy (the “cat’s eye” effect). 

With the varieties established, let’s dive into epidote’s symbolism and past.

Epidote Meaning & History

Epidote symbolizes manifestation, karma, and personal growth. It’s nicknamed the “attraction stone” in spiritual circles for the belief that it helps attract the energies its wearer gives off to the world. In this way, the stone encourages you to give what you want to receive and focus on positivity. 

One character in Greek mythology has virtually the same name as the stone, Epidotes. Epidotes was a spirit or deity of purification. He doesn’t appear throughout many myths, but he is part of a legend wherein he stops the god of thunder, Zeus, from taking out his anger on a Spartan military general named Pausanias. 

History

Epidotes’ name translates to “bountiful” or “giver.” However, the mineral name “epidote” instead derives from the Greek epidosis meaning “increase” or “addition.” This reflects the fact that the base of prismatic epidote crystals have one longer side and one shorter side. It may also reflect its many crystal faces.

The first official discovery, description, and name for epidote came from acclaimed French mineralogist René Just Haüy in 1801. You may recognize Haüy as being the first to describe other minerals like euclase, diaspore, nepheline, and sphene. In fact, he also named nepheline and diaspore in 1801. 

Clearly, Haüy was great at naming minerals. But what is an epidote crystal good for?

Epidote Healing Properties

Like many crystals, epidote can function as a potent healing stone. Its powers are partly influenced by the energies of its coloring. As a predominantly green stone, epidote joins other green gemstones in encouraging optimism, personal growth, and good luck.

Below, we’ll look at more specific epidote uses for physical, emotional, and chakra healing.

Physical Healing

Crystal healers use epidote’s physical healing properties for:

  • Purifying the body

  • Improving memory

  • Increasing endurance

  • Easing tension

  • Strengthening the immune system

  • Boosting blood circulation

  • Speeding up recovery after illnesses or accidents

Emotional Healing

Emotionally, epidote crystals can enhance creativity while attracting abundance, prosperity, and romance. It’s also great for helping you better understand yourself and your desires. Through this process, the stone can bring repressed feelings to the surface and help you communicate these feelings to others without being overwhelmed by them.

Chakra Healing

One benefit of green gemstones is that they are great for heart chakra healing. Chakra healing is an ancient practice of resolving blockages in particular energy centers along your body (chakras) to bring the system back into balance. 

When your heart chakra is blocked, you may shut yourself off from others, experience low self-esteem, and struggle with changing circumstances. After using epidote as a chakra stone, your open heart chakra will bring feelings of self-love, compassion, and acceptance.

Of course, you’ll have to buy the stone before you can start healing with it. Next, we’ll tell you what value factors to look for so you can ensure you get a great deal.

Epidote Gemstone Properties

Epidote grading involves looking at where the stone falls in terms of color, cut, transparency, luster, clarity, and carat weight. 

Color

Among epidote’s various shades of yellow, green, and brown to almost black, the classic shades of pistachio or yellow-green are most desirable. Lighter hues are also valuable because they typically show the stone’s transparency, pleochroism, and color better. 

Increasing amounts of iron impurities give epidotes a green to increasingly brown color. More aluminum means lighter colors, which is why clinozoisite (which has more aluminum) tends to be paler. 

Cut

High-quality transparent, green epidote is often faceted for collectors. Common cuts are octagons, ovals, and cushions, with hearts or trillions being rarer. Lapidarists (gem cutters) must orient their faceted cuts carefully to properly bring out the epidote's pleochroism. 

Collectors also seek out raw epidote (uncut) when the crystals are long and twinned with a strong glassy luster. Opaque epidotes are more often cut as cabochons, beads, or carvings. Chatoyant epidote must be cut as a cabochon to properly display its “cat eye” reflection.

Transparency & Luster

While epidote crystals can be transparent to nearly opaque, the transparent gem material is the most valued. Vitreous (glassy) luster is a sign of high-quality epidote, while resinous luster is a sign of lower quality.

The best transparent material is often what gets faceted into gemstones. 

Clarity

Clarity describes the amount of visible inclusions in a gemstone. Epidotes may have fluid inclusions or mineral inclusions like titanite and magnetite. If these affect its transparency, they may lower the stone’s value. More often, epidote is an inclusion in other stones like quartz or prehnite

Carat Weight

Facetable epidote is already hard to find, and finding gem-quality material that can yield faceted stones over 5 carats is rare. Any faceted epidote gemstones around 5 carats or higher are very valuable. 

Speaking of finding gem material, how does epidote form and where does it come from? 

epidote gemstone rough specimen

Epidote Formation & Sources

Epidotes can form through two types of metamorphism: regional and contact. Regional metamorphism involves mostly heat (through nearby magma) changing the composition of minerals inside a rock. Contact metamorphism involves both heat and pressure yielding a similar result.

Because of this, epidote is often found in metamorphic rocks like marble, hornfels, and skarns, along with metamorphosed schists and limestones. Less often, you’ll find epidote in igneous rocks like basalt or granite pegmatites. 

Geographically, where is epidote found? 

Mining Locations

The most abundant source of epidote is eastern France. High-quality epidote gem material also comes from Russia.

Additional epidote sources include:

  • Australia

  • Austria

  • Austrian & French Alps

  • Brazil

  • Burma

  • Canada

  • Czechia

  • England

  • Finland

  • Germany

  • Italy

  • Japan

  • Kenya

  • Korea

  • Madagascar

  • Mexico

  • Mozambique

  • Norway

  • Scotland

  • Sweden

  • Switzerland

  • Sri Lanka

  • Tasmania

  • USA (Alaska, Connecticut, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Rhode Island, Washington)

Now, what epidote gemstone prices should you expect? 

epidote gemstone faceted ring

Epidote Price & Value

The epidote price per carat largely depends on the type of stone or cut we’re talking about. Faceted gems are the priciest, ranging from $30-$300 per carat at wholesale. 

Epidote rough costs around $0.10-$0.50 per carat at wholesale. Well-formed, uncut crystals with good coloring are around $0.90-$2.50 per carat. Cabochons are usually around $0.40 per carat at wholesale.

Epidote beads for earrings and pendants are around $15 to $25 each. 

Lastly, let’s discuss proper gemstone care for epidote. 

Epidote Care and Maintenance

Epidote’s cleavage and fragility mean you have to be careful when handling it. We recommend opting for epidote jewelry with protective settings.

This stone is sensitive to high heat and hydrochloric acid, so keep it away from both. Also, don’t clean it with harsh chemicals like household cleaners. 

Instead, you can safely clean epidote with a soft, dust-free cloth along with mild soap mixed into lukewarm water. Don’t use ultrasonic or steam cleaners. 

Store epidote in a velvet or fabric pouch separately from other gems. Keep the pouch in a place away from any high heat like direct sunlight.

綠簾石 Epidote 是一種常見的黃綠色到綠色寶石,類似於開心果的顏色。綠簾石是罕見的還是常見的?作為一種礦物,綠簾石在世界範圍內普遍存在且儲量豐富。然而,這種寶石的脆弱性使得刻面綠簾石寶石非常罕見。

除了本身是寶石外,綠簾石也是一組寶石,其中包括像黝簾石這樣的石頭。您可能還會將綠簾石視為其他寶石中的內含物

在尋找綠簾石珠寶?只是想更多地了解這塊鬱鬱蔥蔥的石頭?請繼續關注我們介紹了 Epidote 的所有特性、治療能力、價格等。

綠簾石

關於綠簾石

Epidote 是一種呈黃色到綠色的半寶石,但由於色調可能很深,它可能會呈現棕色或黑色。

乍一看,您可能會疑惑:綠簾石是綠碧璽嗎?不,綠色碧璽(和一般的碧璽)是一種獨立的寶石。雖然顏色相似,但綠色碧璽沒有綠簾石的解理,綠碧璽也沒有碧璽的三角形或六角形橫截面。

另一個常見的混淆是綠簾石與橄欖石。橄欖石(又名貴橄欖石或橄欖石)是一種綠色矽酸鎂鐵。最明顯的區別是綠簾石通常在石英內部或周圍發現,而橄欖石從未在石英附近發現。

幸運的是,綠簾石與橄欖石的相似性意味著它也可以成為傳統八月生日石更實惠的替代品。就其本身而言,綠簾石是雙子座的生肖石

除了寶石用途外,綠簾石沒有任何工業用途。

其次,綠簾石是什麼石頭?

棕色綠簾石寶石水晶包裹

綠簾石規格和特徵

作為鈣鋁鐵矽酸鹽,綠簾石礦物分子式為Ca2(Al,Fe)3(SiO4)3(OH)。石頭屬於同名的綠簾石礦物組,是最常見的成員。該組中的其他寶石包括黝簾石、斜長石、褐榴石和皮蒙石。

斜長石和綠簾石極為相似,幾乎無法區分,因此您可能會看到賣家將這些寶石標記為“斜長石-綠簾石”。一些標本由兩種礦物組成。

綠簾石的主要晶體習性是具有縱向面的柱狀棱柱體。它也經常形成孿晶。

你如何識別綠簾石?最簡單的測試是用折射計測量寶石的雙折射率,因為綠簾石的雙折射率高於大多數寶石。

以下是綠簾石的剩餘礦物數據,包括其雙折射值:

  • 莫氏硬度:6-7

  • 顏色: 綠色、黃綠色、黃色、棕色、墨綠色

  • 晶體結構: 單斜

  • 光澤: 玻璃狀(玻璃狀)、珍珠狀、樹脂狀或油膩狀

  • 透明度:透明到半透明,有時接近不透明

  • 折射率:1.72-1.77

  • 密度:3.35-3.50

  • 乳溝:完美,1 向;好,1 方向

  • 骨折:不規則/不均勻

  • 條痕:灰白色

  • 發光: 無

  • 多色性:黃色、綠色和棕色存在且強烈

  • 雙折射:0.019-0.045

  • 色散:強; 0.030

綠簾石的類型

Epidote 有一個有點官方的變體。還有另一種石頭主要由綠簾石和一種顯示光學現象的特殊類型的綠簾石組成。這些都是:

  • Pistacite :開心果綠綠簾石品種,偶爾會刻成小寶石

  • Unakite :主要由綠簾石和其他礦物組成的拋光岩石

  • 貓眼綠簾石:包含平行纖維的綠簾石,通過貓眼的光學效應(“貓眼”效應)產生單束反射光。

隨著品種的建立,讓我們深入了解 epidote 的象徵意義和過去。

綠簾石寶石戒指刻面

Epidote 的意義和歷史

Epidote 象徵著表現、業力和個人成長。它在精神界被暱稱為“吸引力石”,因為人們相信它有助於吸引佩戴者散發給世界的能量。通過這種方式,石頭鼓勵您付出您想要得到的東西,並專注於積極性。

希臘神話中的一個人物幾乎與石頭同名,Epidotes。 Epidotes 是一種精神或淨化之神。他並沒有出現在許多神話中,但他是一個傳說的一部分,在這個傳說中,他阻止了雷神宙斯對一位名叫保薩尼亞斯的斯巴達軍事將軍發怒。

歷史

Epidotes 的名字翻譯為“豐富的”或“給予者”。然而,礦物名稱“epidote”卻源自希臘語epidosis ,意思是“增加”或“增加”。這反映了這樣一個事實,即棱柱狀綠簾石晶體的底部有一個較長的邊和一個較短的邊。它也可能反映出它的許多晶面。

綠簾石的第一個官方發現、描述和名稱來自 1801 年著名的法國礦物學家 René Just Haüy。您可能認為 Haüy 是第一個描述其他礦物(如桉長石水鋁石霞石榍石)的人。事實上,他在 1801 年還命名了霞石和硬水鋁石。

顯然,Haüy 非常擅長命名礦物。但是綠簾石水晶有什麼用呢?

綠色綠簾石癒合晶體

綠簾石的治療特性

像許多水晶一樣,綠簾石可以作為一種有效的治療石。它的力量部分受到其著色能量的影響。作為一種以綠色為主的寶石,綠簾石與其他綠色寶石一起鼓勵樂觀、個人成長和好運。

下面,我們將看看更具體的 epidote 用途,用於身體、情感和脈輪治療。

身體治療

水晶治療師將綠簾石的物理治療特性用於:

  • 淨化身體

  • 提高記憶力

  • 增加耐力

  • 緩解緊張

  • 增強免疫系統

  • 促進血液循環

  • 加快疾病或事故後的恢復

情緒療愈

在情感上,綠簾石可以增強創造力,同時吸引富足、繁榮和浪漫。它也非常有助於幫助您更好地了解自己和您的願望。通過這個過程,石頭可以將壓抑的感受浮出水面,幫助您將這些感受傳達給他人,而不會被它們淹沒。

脈輪療愈

綠色寶石的好處之一是它們非常適合心輪癒合。脈輪療愈是一種解決身體特定能量中心(脈輪)阻塞,使系統恢復平衡的古老實踐。

當您的心輪受阻時,您可能會與他人隔絕,感到自卑,並在不斷變化的環境中掙扎。使用綠簾石作為脈輪石後,您開放的心輪會帶來自愛、同情和接受的感覺。

當然,您必須先購買石頭,然後才能開始使用它進行治療。接下來,我們將告訴您要尋找哪些價值因素,以確保您獲得划算的交易。

橙棕色綠簾石多面寶石

綠簾石寶石特性

綠簾石分級包括根據顏色、切工、透明度、光澤、淨度和克拉重量來查看寶石的落點。

顏色

在綠簾石的黃色、綠色、棕色到幾乎黑色的各種色調中,經典的開心果色或黃綠色是最令人嚮往的。較淺的色調也很有價值,因為它們通常能更好地顯示寶石的透明度、多色性和顏色。

越來越多的鐵雜質使綠簾石呈綠色到越來越深的棕色。更多的鋁意味著更淺的顏色,這就是為什麼斜長石(含有更多的鋁)往往更淺的原因。

高品質透明綠色綠簾石通常為收藏家刻面。常見的切工有八角形、橢圓形和墊形,心形或萬億形更為罕見。寶石學家(寶石切割師)必須仔細調整刻面切割的方向,以正確顯示綠簾石的多色性。

當晶體很長且具有強烈的玻璃光澤時,收藏家還會尋找原始綠簾石(未切割)。不透明的綠簾石更常被切割成凸圓形、珠子或雕刻品。 Chatoyant epidote 必須切割成凸圓形,以正確顯示其“貓眼”反射。

薄荷綠綠簾石多面寶石

透明度和光澤

雖然綠簾石晶體可以是透明的,也可以是幾乎不透明的,但透明的寶石材料是最有價值的。玻璃質(玻璃狀)光澤是優質綠簾石的標誌,而樹脂光澤是低品質的標誌。

最好的透明材料通常是被刻面成寶石的材料。

明晰

淨度描述了寶石中可見內含物的數量。綠簾石可能含有流體包裹體或礦物包裹體,如鈦鐵礦磁鐵礦。如果這些影響其透明度,它們可能會降低寶石的價值。更常見的是,綠簾石是石英葡萄石等其他寶石中的內含物。

克拉重量

刻面綠簾石已經很難找到,找到能夠生產超過 5 克拉刻面寶石的寶石級材料也很罕見。任何約 5 克拉或更大的刻面綠簾石寶石都非常有價值。

說到尋找寶石材料,綠簾石是如何形成的,又從何而來?

綠簾石原石標本

綠簾石的形成和來源

綠簾石可以通過兩種類型的變質作用形成:區域變質作用和接觸變質作用。區域變質作用主要涉及熱量(通過附近的岩漿)改變岩石內部礦物的成分。接觸變質涉及產生類似結果的熱量和壓力。

正因為如此,綠簾石通常存在於變質岩中,如大理石、角岩和矽卡岩,以及變質的片岩和石灰岩。不太常見的是,您會在玄武岩或花崗岩偉晶岩等火成岩中發現綠簾石。

從地理上講,在哪裡可以找到綠簾石?

採礦地點

綠簾石最豐富的來源是法國東部。優質的綠簾石寶石原料也來自俄羅斯。

其他綠簾石來源包括:

  • 澳大利亞

  • 奧地利

  • 奧地利和法國阿爾卑斯山

  • 巴西

  • 緬甸

  • 加拿大

  • 捷克語

  • 英國

  • 芬蘭

  • 德國

  • 意大利

  • 日本

  • 肯尼亞

  • 韓國

  • 馬達加斯加

  • 墨西哥

  • 莫桑比克

  • 挪威

  • 蘇格蘭

  • 瑞典

  • 瑞士

  • 斯里蘭卡

  • 塔斯馬尼亞

  • 美國(阿拉斯加、康涅狄格、馬薩諸塞、密歇根、新罕布什爾、新澤西、紐約、羅德島、華盛頓)

現在,您應該期待什麼樣的綠簾石寶石價格?

綠簾石寶石刻面戒指

Epidote 的價格和價值

每克拉的綠簾石價格在很大程度上取決於我們所談論的寶石類型或切工。刻面寶石是最昂貴的,批發價從每克拉 30-300 美元不等。

綠簾石原石的批發價約為每克拉 0.10-0.50 美元。形狀良好、未切割且著色良好的晶體價格約為每克拉 0.90 至 2.50 美元。凸圓形寶石的批發價通常為每克拉 0.40 美元左右。

用於耳環和吊墜的Epidote 珠子每個大約 15 到 25 美元。

最後,讓我們討論一下綠簾石的適當寶石護理

Epidote 保養和維護

Epidote 的乳溝和脆弱性意味著您在處理它時必須小心。我們建議選擇帶有保護設置的綠簾石首飾。

此石材對高溫和鹽酸敏感,因此請遠離兩者。另外,請勿使用家用清潔劑等刺激性化學品清潔它。

相反,您可以使用柔軟的無塵布和溫水中混合的溫和肥皂來安全地清潔綠簾石。不要使用超聲波或蒸汽清潔器。

將綠簾石與其他寶石分開存放在天鵝絨或織物袋中。將袋子放在遠離任何高溫的地方,如陽光直射。
