almandine gemstoneAlmandine is a deep red or magenta to brownish-black garnet gemstone variety used and adored since ancient times. It’s arguably the most well-known garnet alongside pyrope.

Is almandine rare or common? Almandine garnets are very common — the most common garnet variety, in fact. That said, gem-quality almandine crystals make up a small portion of all almandine mined. Since they’re so abundant, though, they make beautiful and affordable gems!

So, what’s the almandine garnet price range? And what makes this gem special? We’ll answer all that and more in this almandine garnet gemstone guide.

What Is Almandine Garnet?

Almandine garnet is a semi-precious gemstone that serves as the traditional January birthstone. It’s also a lucky zodiac stone for Capricorn and Aquarius and the traditional 2nd wedding anniversary gemstone. If you live in Connecticut, USA, almandine garnet is your official state gemstone!

In the UK, almandine may be called “almandite.” Other alternative names include:

  • Precious garnet

  • Oriental garnet

  • Carbuncle

  • Almandine ruby

The nickname “carbuncle” has historical relevance we’ll cover more later, but the name “almandine ruby” is a misnomer, as garnets and rubies are separate gems.

Outside of gorgeous gems, almandine also has many industrial uses. 

Because of its superior Mohs hardness among garnets, almandine is great for abrasives. These abrasives may be used in sandpaper or replace silica for sandblasting. 

Industrial-grade garnets produced for abrasives may be called “rock garnet.” Some unexpected applications for abrasive garnet are woodworking and water filtration. 

Additionally, garnets can help geologists study the temperatures and pressures that rocks form under in a field called geothermobarometry. They can similarly indicate geological timelines when used as a geochronometer or thermochronometer.

Almandine Specifications & Characteristics

Almandine is in the pyralspite garnet series along with pyrope and spessartite. The pyralspite group is aluminum-rich, contrasting the calcium-rich ugrandite series — which includes uvarovite, grossular, and andradite. 

As an iron aluminum silicate, almandine’s chemical formula is Fe3Al2Si3O12 or Fe3Al2(SiO4)3. To identify almandine, its absorption spectrum is key. Absorption spectrum describes which colors do and don’t pass through when white light is shone into the gem. 

With a spectroscope, you’ll see three strong absorption bands in almandines (or almandine-dominant garnets): a strong one that’s 200 Å wide at 5760 and two more strong ones at 5260 and 5050. 

Here are all of almandine’s properties: 

  • Mohs hardness: 7-7.5

  • Color: Deep red, violet-red, reddish-brown, brownish-black, black; Rarely purple or pink; Sometimes black and red

  • Crystal structure: Isometric/Cubic

  • Luster: Vitreous, greasy, or resinous - rough; Vitreous to sub-adamantine - polished

  • Transparency: Transparent to opaque

  • Refractive index: 1.75-1.83

  • Density: 3.93-4.30 (star garnet can reach 4.76)

  • Cleavage: None

  • Fracture: Conchoidal to uneven

  • Streak: White

  • Luminescence: None

  • Pleochroism: None

  • Optical effects: Asterism; Very rarely color-change

Types of Almandine

Like most garnets, and pyrope especially, almandine is almost never pure; you’ll usually find it mixed with pyrope or spessartite. Some varieties containing almandine include:

Mozambique Garnet

Mozambique garnets are red with brown and orange undertones. Discovered in Mozambique, Africa, these are almandine and pyrope. 

Rhodolite

Rhodolite is a commonly purplish-red blend of almandine and pyrope. It can also be pale rose-red, violet, or purple shades. Spessartite added means paler hues. Iron and magnesium impurities create deep purple “grape garnet” rhodolites.

Bright magenta-rose Tanzanian rhodolites with pale pink flashes combine all three pyralspites. These are called “Umbalite garnets.”

The most valuable rhodolites are bright purple, while redder hues are less valuable.

Malaya (Malaia) Garnet

Malaya (or Malaia) garnet is usually a pyrope-spessartite, but it can also contain almandine and grossular garnet. These are pink, salmon, orange, or red. 

Color Change Garnet

All garnets can be color-changing, though this is rare in almandines. One is the almandine-grossular-spessartite mixture, displaying greenish-yellow or brown hues shifting to purplish-red. 

Other color-changing almandines include:

  • Idaho: Pyrope-almandine, red to purple-red

  • Norway: Pyrope-almandine, violet-red to blue-green or violet to wine-red

Star Garnet

Almandine Meaning & History

The almandine crystal symbolizes deep love, passion, and desire. Individually, the stone also represents courage, achievement, and protection. Persian legends say almandines protect against natural disasters, indicating incoming danger by becoming paler.

Almandine garnets have been known for centuries. The almandine name comes from a mistaken interpretation of alabandicus, given by Roman scholar Pliny the Elder in the 1st century AD. Alabanda was an Asia Minor town where almandines came from.

These cabochons were historically called “carbuncles,” Latin for “live coal” because the darker red stones resembled charcoal on fire. You may see “carbuncle” for vintage jewelry items.

History

The oldest evidence currently available reveals ancient Egyptian uses of almandine dating to 3,500 BC. 

Red garnets like almandine sat among the most popular gems during Late Antiquity, from 4th-6th century AD. One popular use was decorative metalwork inlay called cloisonné.

One notable artifact is the Winfarthing pendant, a 7th-century brooch found in Norfolk, England, in 2014. The gold brooch contained hundreds of tiny almandine gems.

Garnet jewelry saw its highest popularity during the Victorian Era, from 1837 to 1901. Before this time, only royalty, nobles, and clergy could afford gems like garnets. The Industrial Revolution made garnets accessible to the masses.

However, wide accessibility lowered garnet’s popularity, as it became less associated with status. Luckily, that also meant more affordable prices!

In 1967, Idaho, USA, named star garnet their state gem. Similarly, Connecticut, USA, named almandine garnet the state’s official gemstone in 1977.

Almandine Healing Properties

Like all gems, almandine’s color influences its power as a healing stone. Typical red hues evoke the passion, drive, and energy of red gemstones

Meanwhile, brown hues are great for grounding, especially when used as chakra stones for opening the root chakra — bringing strength and connection!

Stronger purple coloring in almandine brings the purple gemstone benefits of spiritual awakening and wisdom. 

Physical Healing

Purported physical benefits of almandine include increasing:

  • Strength & endurance

  • Fertility & libido

  • Blood circulation

  • Iron absorption

  • Immune system function

Emotional Healing

Emotional almandine garnet benefits are said to boost feelings of:

  • Connection

  • Resilience

  • Stability

  • Motivation

Apart from its healing powers, is almandine garnet valuable? It depends on its properties.

Almandine Gemstone Properties

Almandine is graded based on the standard categories of color, cut, clarity, carat weight, and treatments. 

Color

The color of almandine ranges from classic deep reds and purplish-reds to brownish hues. The iron content is responsible for some of the coloring, but that iron can also be substituted by manganese (from spessartite) and magnesium, leading to opaque, browner stones.

Classic red hues are generally most valuable, particularly in large, transparent stones as larger sizes are usually too dark. Rhodolite and Malaya garnets with good coloring have the highest prices. 

Cut

Most faceted garnets are almandine, and the shapes are endless. Carvings are less common, but many historical or designer almandine carvings are valuable. Almandines may also be cut as beads.

Though cabochons (often called “carbuncles”) are slightly less common, the star garnet variety must be cut en cabochon to display its asterism. These can be quite valuable, as star garnets are notoriously tricky to cut correctly. 

Clarity

Clarity describes the extent of visible inclusions in a stone. Almandines usually have a Type I colored gemstone clarity grade, meaning little to no eye-visible inclusions. Pyrope-almandine mixtures may be Type II, with some visible inclusions.

That said, some possible inclusions in almandine stones are:

  • Needles (hornblende, rutile, augite)

  • Crystals (e.g. spinel, biotite, apatite, quartz, ilmenite, monazite) that may appear speckled, irregular, or knobby

  • Dense rods (hornblende)

  • Crystals with “halos” from natural irradiation (zircon), most from Sri Lanka

While these inclusions generally lower value, certain fibrous inclusions of amphibole or pyroxene minerals that cause asterism increase value.

Carat Weight

Almandine crystals vary in size, but smaller crystals show better coloring. When formed in a matrix that becomes weathered, it can separate into well-formed, often large crystals. That said, broken crystals from some locales may only yield gems under 2 carats. 

Most almandine gems won’t significantly change in price-per-carat based on their size. 

The exceptions are rhodolite — which increases in rate based on whether it’s under 1 carat, under 10 carats, or over 10 carats — and Malaya — which increases in rate for under 1 carat, under 5 carats, and over 5 carats. 

Currently, the largest almandine is 174 carats!

Treatments & Synthetics

While uncommon, some almandines may be treated. Usually, almandine-spessartite or pyrope-almandine garnets are heated to create a metallic coating, sometimes of hematite. The latter were historically called “Proteus garnets.” 

The majority of synthetic almandines (which are less valuable) are created through hydrothermal growth. You can identify these based on the presence of seed plates.

Almandine Formation & Sources

Like most garnets, almandine usually forms when aluminum-rich, sedimentary rocks undergo metamorphic changes from pressure and heat. These conditions alter the minerals inside into garnet.

You’ll find almandine in metamorphic rocks like mica-rich garnet schists, where it may form in a matrix with the rock. They’re also found in alluvial deposits and igneous rocks. 

Mining Locations

New York, USA contains the world’s largest garnet mine, producing roughly 90 percent of the world’s industrial garnet. Industrial “rock garnet” also comes from China and India. 

For gem-quality almandine, India and Brazil are top producers. Other sources include:

  • Afghanistan

  • Austria

  • Canada

  • Czechia

  • Ethiopia

  • Greenland

  • Japan

  • Kenya

  • Myanmar

  • Norway

  • Pakistan

  • Russia

  • Solomon Islands

  • Sweden

  • Tanzania

  • Uruguay

  • USA (Alaska, Colorado, Connecticut, Maine, Michigan, Pennsylvania, South Dakota)

  • Vietnam

  • Zambia

The main almandine variety sources are: 

  • Malaya: Kenya, Madagascar, Tanzania

  • Rhodolite: Brazil, India, North Carolina (USA), Sri Lanka, Tanzania, Thailand

  • Mozambique: Mozambique (shocker)

Large almandines are known from Madagascar and Sri Lanka.

Almandine Price & Value

Because almandine is the most common garnet, most are affordable. The only exceptions are the rare rhodolite and Malaya garnets.

First, let’s look at almandine garnet price-per-carat ranges that don’t change by size. “Top color” almandines refer to those with moderately strong saturation, medium-dark tone, and these colors: orange-red, red, purplish-red, reddish-purple.

  • Top Color: $1-$30 per carat

  • Mozambique: $5-$35 per carat

Red to purple almandine cabochons are also $1-$20 per carat, regardless of size. 

The faceted gem prices by size for rhodolite are:

  • 0.5 to 1 carat: $20-$100 per carat

  • 1 to 10 carats: $20-$150 per carat

  • Over 10 carats: $150-$300 per carat

Now, the faceted prices for Malaya garnets:

  • 0.5 to 1 carat: $30-$60 per carat

  • 1 to 5 carats: $150-$200 per carat

  • Over 5 carats: $300-$3,000 per carat

Mozambique garnet cabochons are always $5-$7 per carat. The ranges for rhodolite cabochons are $4-$6 per carat under 1 ct, $5-$30 per carat when 1-10 cts, and up to $40 per carat when over 10 cts.

Almandine carvings are also pricier, starting at $450 and reaching $84,500.

Gem-quality raw almandine crystals are generally $0.02-$0.08 per carat. 

Almandine Care and Maintenance

Luckily, gemstone care for almandine is easy! No cleavage and good hardness makes this stone durable enough for daily wear. You may opt for protective settings in a more vulnerable almandine garnet ring to prevent scratches, though.

You can clean almandine gently with mild soap, warm water, and a soft toothbrush. Don’t use mechanical or steam cleaners. 

Almandines with inclusions are more sensitive to extreme heat. Store the gem in a cool, dry place away from other stones.

鐵鋁榴石鐵鋁榴石是一種深紅色或洋紅色到棕黑色石榴石寶石品種,自古以來就使用和崇拜。它可以說是除了鎂鋁榴石之外最著名的柘榴石。

鐵鋁榴石是稀有還是常見?鐵鋁榴石非常常見——事實上是最常見的石榴石品種。也就是說,寶石級鐵鋁榴石晶體僅佔所有開采的鐵鋁榴石的一小部分。但是,由於它們如此豐富,它們製作出美麗價格合理的寶石!

那麼,鐵鋁榴石的價格範圍是多少?是什麼讓這顆寶石與眾不同?我們將在這本鐵鋁榴石寶石指南中回答所有這些問題以及更多內容。

鐵鋁榴石

什麼是鐵鋁榴石?

鐵鋁榴石是一種半寶石,是傳統的一月生日石。它也是摩羯座和水瓶座的幸運生肖石和傳統的結婚紀念日寶石。如果您住在美國康涅狄格州,鐵鋁榴石是您的官方寶石!

在英國,almandine 可能被稱為“almandite”。其他替代名稱包括:

  • 珍貴的石榴石

  • 東方石榴石

  • 鐵鋁榴石

“carbuncle”這個綽號具有歷史意義,我們稍後會詳細介紹,但“almandine ruby”這個名稱用詞不當,因為石榴石和紅寶石是不同的寶石。

除了華麗的寶石外,鐵鋁榴石還有許多工業用途。

由於其在石榴石中具有卓越的莫氏硬度,鐵鋁榴石非常適合用作磨料。這些磨料可用於 砂紙或代替二氧化矽進行噴砂。

為磨料生產的工業級石榴石可稱為“石榴石”。磨料石榴石的一些意想不到的應用是木工和水過濾。

此外,石榴石可以幫助地質學家研究岩石在地熱氣壓測量領域中形成的溫度和壓力。當用作地球計時器或溫度計時,它們同樣可以指示地質時間線。

Almandine 規格和特性

Almandine 與鎂鋁榴石錳鋁榴石一起屬於 pyralspite石榴石系列。 pyralspite 組富含鐵,與富含鈣的 ugrandite 系列形成鮮明對比 - 其中包括uvaroviteGrossular和 andradite 。

作為一種鐵鋁矽酸鹽,鐵鋁榴石的化學式為 Fe3Al2Si3O12 或 Fe3Al2(SiO4)3。要識別鐵鋁榴石,其吸收光譜是關鍵。吸收光譜描述了當白光照射到寶石中時哪些顏色可以通過和不可以通過。

使用分光鏡,您會在鐵鋁榴石(或以鐵鋁榴石為主的石榴石)中看到三個強吸收帶:一個強吸收帶,在 5760 處寬 200 Å,另外兩個強吸收帶在 5260 和 5050 處。

以下是almandine的所有特性:

  • 莫氏硬度:7-7.5

  • 顏色:深紅色、紫紅色、紅棕色、棕黑色、黑色;很少有紫色或粉紅色;有時黑色和紅色

  • 晶體結構:等距/立方

  • 光澤:玻璃質、油膩或樹脂狀——粗糙;玻璃質至亞金剛砂 - 拋光

  • 透明度:透明到不透明

  • 折射率:1.75-1.83

  • 密度:3.93-4.30(星石榴石可達4.76)

  • 乳溝: 無

  • 斷裂:貝殼狀到不均勻

  • 條紋:白色

  • 發光:無

  • 多色性:無

  • 光學效果:星光;很少變色

鐵鋁榴石的種類

像大多數柘榴石,尤其是鎂鋁榴石一樣,鐵鋁榴石幾乎從來都不是純淨的。你通常會發現它與鎂鋁榴石或錳鋁榴石混合在一起。一些含有鐵鋁榴石的品種包括:

莫桑比克石榴石

鐵鋁榴石莫桑比克石榴石寶石刻面

莫桑比克石榴石呈紅色,帶有棕色和橙色底色。在非洲莫桑比克發現的這些是鐵鋁榴石和鎂鋁榴石。

紅榴石

鐵鋁榴石 葡萄石榴石 寶石 多面

Rhodolite 是一種常見的紫紅色的鐵鋁榴石和鎂鋁榴石的混合物。它也可以是淡玫瑰紅色、紫羅蘭色或紫色色調。添加的錳鋁石意味著更淺的色調。鐵和鎂雜質會形成深紫色的“葡萄石榴石”榴石。

帶有淡粉色閃光的明亮洋紅色玫瑰色坦桑尼亞 rhodolites 結合了所有三種 pyralspites。這些被稱為“Umbalite garnets”。

最有價值的 rhodolites 是亮紫色,而較紅的色調則價值較低。

馬來亞(Malaia)石榴石

馬來亞(或 Malaia)石榴石通常是鎂鋁錳鋁榴石,但也可能含有鐵鋁榴石和鈣鋁榴石。這些是粉紅色、鮭魚色、橙色或紅色。

變色石榴石

顏色變化 鐵鋁榴石 石榴石 寶石 刻面

所有柘榴石都可以變色,儘管這在鐵鋁榴石中很少見。一種是鐵鋁錳鋁榴石-錳鋁榴石混合物,呈現綠黃色或棕色色調轉變為紫紅色。

其他顏色變化的almandines包括:

  • 愛達荷州: Pyrope-almandine, 紅色至紫紅色

  • 挪威: Pyrope-almandine, 紫紅色到藍綠色或紫羅蘭色到酒紅色

星石榴石

Almandine 的意義和歷史

鐵鋁榴石水晶象徵著深深的愛、激情和渴望。單獨來看,這塊石頭也代表勇氣、成就和保護。波斯傳說說,almandines 可以抵禦自然災害,通過變得蒼白來預示即將到來的危險。

幾個世紀以來,鐵鋁榴石就為人所知。 almandine 這個名字來自公元 1 世紀羅馬學者老普林尼對 alabandicus 的錯誤解釋。阿拉班達是小亞細亞的一個小鎮,鐵鋁榴彈就來自於此。

這些凸圓形在歷史上被稱為“carbuncles”,拉丁語為“活煤”,因為較深的紅色石頭類似於燃燒的木炭。您可能會在復古首飾上看到“carbuncle”。

歷史

目前可獲得的最古老的證據表明,古埃及使用的鐵鋁榴石可追溯到公元前 3,500 年。

從公元 4 世紀到 6 世紀晚期,像鐵鋁榴石這樣的紅色石榴石是最受歡迎的寶石之一。一種流行的用途是稱為景泰藍的裝飾性金屬製品鑲嵌。

一件值得注意的文物是 Winfarthing 吊墜,這是 2014 年在英格蘭諾福克發現的 7 世紀胸針。金胸針包含數百顆微小的鐵鋁榴石寶石。

石榴石首飾在 1837 年至 1901 年的維多利亞時代最為流行。在此之前,只有皇室、貴族和神職人員才能買得起石榴石等寶石。工業革命使石榴石為大眾所用。

然而,廣泛的可及性降低了石榴石的受歡迎程度,因為它與地位的聯繫越來越少。幸運的是,這也意味著更實惠的價格!

1967 年,美國愛達荷州將星形石榴石命名為他們的州級寶石。同樣,美國康涅狄格州於 1977 年將鐵鋁榴石命名為該州的官方寶石。

almandine 石榴石癒合水晶

Almandine 癒合特性

像所有寶石一樣,鐵鋁榴石的顏色會影響其作為治療石的力量。典型的紅色調喚起紅色寶石的激情、動力和能量。

同時,棕色色調非常適合接地,特別是當用作打開根脈輪的脈輪石時 - 帶來力量和聯繫!

鐵鋁榴石中較強的紫色帶來了精神覺醒和智慧的紫色寶石益處。

物理治療

據稱鐵鋁榴石的身體益處包括增加:

  • 力量與耐力

  • 生育力和性慾

  • 血液循環

  • 鐵吸收

  • 免疫系統功能

情緒療愈

據說具有情緒化的鐵鋁榴石可以增強以下感覺:

  • 聯繫

  • 彈力

  • 穩定

  • 動機

除了它的治療能力,鐵鋁榴石還有價值嗎?這取決於它的屬性。

紅鋁榴石柘榴石寶石包裹

鐵鋁榴石寶石屬性

鐵鋁榴石根據顏色、切工、淨度、克拉重量和處理等標準類別進行分級。

顏色

鐵鋁榴石的顏色範圍從經典的深紅色和紫紅色到褐色色調。鐵含量是造成某些顏色的原因,但鐵也可以被錳(來自錳鋁石)和鎂代替,從而產生不透明的褐色寶石。

經典的紅色色調通常是最有價值的,特別是在大型透明寶石中,因為較大的尺寸通常太暗。具有良好著色的紅榴石和馬來亞石榴石價格最高。

大多數刻面石榴石是鐵鋁榴石,形狀無窮無盡。雕刻不太常見,但許多歷史悠久的或設計師設計的鐵鋁榴石雕刻都很有價值。 Almandines 也可以被切割成珠子

雖然凸圓形(通常稱為“carbuncles”)不太常見,但星形石榴石品種必須切成凸圓形以顯示其星光。這些可能非常有價值,因為眾所周知,星形石榴石很難正確切割。

明晰

淨度描述了寶石中可見內含物的程度。鐵鋁榴石通常具有 I 型有色寶石淨度等級,這意味著幾乎沒有肉眼可見的內含物。 Pyrope-almandine 混合物可能是 II 型,帶有一些可見的內含物。

也就是說,鐵鋁榴石中一些可能的內含物是:

  • 針(角閃石、金紅石、輝石)

  • 可能出現斑點、不規則或多節的晶體(例如尖晶石、黑雲母、磷灰石石英、鈦鐵礦、獨居石)

  • 緻密棒(角閃石)

  • 自然輻射產生的帶有“光環”的晶體(鋯石),大部分來自斯里蘭卡

雖然這些內含物的價值通常較低,但角閃石或輝石礦物的某些纖維狀內含物會增加價值。

克拉重量

Almandine 晶體大小不一,但較小的晶體顯示更好的顏色。當形成在風化的基質中時,它可以分離成形狀良好的、通常是大的晶體。也就是說,某些地區的破碎水晶可能只能產出 2 克拉以下的寶石。

大多數鐵鋁榴石寶石的每克拉價格不會因尺寸而發生顯著變化。

例外情況是 rhodolite - 根據其是 1 克拉以下、10 克拉以下還是 10 克拉以上來增加比率 - 馬來亞 - 1 克拉以下、5 克拉以下和 5 克拉以上的比率會增加。

目前,最大的鐵鋁榴石重 174 克拉!

處理與合成

雖然不常見,但可能會治療一些硬脂酸橙。通常,鐵鋁錳鋁-錳鋁榴石或鎂鋁榴石-鐵鋁榴石被加熱以形成金屬塗層,有時是赤鐵礦。後者在歷史上被稱為“變形石榴石”。

大多數合成鐵鋁榴石(價值較低)是通過熱液生長產生的。您可以根據種子板的存在來識別這些。

鐵鋁榴石原石

鐵鋁榴石的形成和來源

像大多數石榴石一樣,鐵鋁榴石通常在富含鋁的沉積岩經歷壓力和熱量的變質變化時形成。這些條件將裡面的礦物質變成石榴石。

您會在富含雲母的石榴石片岩等變質岩中發現鐵鋁榴石,它可能與岩石形成基質。它們也存在於沖積層和火成岩中。

採礦地點

美國紐約擁有世界上最大的石榴石礦,生產世界上大約 90% 的工業石榴石。工業“石榴石”也來自中國和印度。

對於寶石級鐵鋁榴石,印度和巴西是頂級生產商。其他來源包括:

  • 阿富汗

  • 奧地利

  • 加拿大

  • 捷克

  • 埃塞俄比亞

  • 格陵蘭

  • 日本

  • 肯尼亞

  • 緬甸

  • 挪威

  • 巴基斯坦

  • 俄羅斯

  • 所羅門群島

  • 瑞典

  • 坦桑尼亞

  • 烏拉圭

  • 美國(阿拉斯加、科羅拉多、康涅狄格、緬因、密歇根、賓夕法尼亞、南達科他州)

  • 越南

  • 贊比亞

主要的鐵鋁榴石品種來源有:

  • 馬來亞:肯尼亞、馬達加斯加、坦桑尼亞

  • Rhodolite : 巴西、印度、北卡羅來納州(美國)、斯里蘭卡、坦桑尼亞、泰國

  • 莫桑比克:莫桑比克(震驚)

馬達加斯加和斯里蘭卡都知道大型鐵鋁榴彈。

鐵鋁榴石價格和價值

因為鐵鋁榴石是最常見的石榴石,所以大多數都是負擔得起的。唯一的例外是稀有的紅榴石和馬來亞石榴石。

首先,讓我們看看不隨尺寸變化的每克拉鐵鋁榴石價格範圍。 “頂色”鐵鋁榴石是指飽和度適中、色調中等偏深的那些,這些顏色是:橙紅色、紅色、紫紅色、紅紫色。

  • 頂部顏色:每克拉 1-30 美元

  • 莫桑比克:每克拉 5-35 美元

紅色到紫色的硬剛玉凸圓形鑽石也是每克拉 1 到 20 美元,無論大小。

紅榴石按尺寸劃分的刻面寶石價格為:

  • 0.5 至 1 克拉:每克拉 20 至 100 美元

  • 1 至 10 克拉:每克拉 20 至 150 美元

  • 超過 10 克拉:每克拉 150-300 美元

現在,馬來亞石榴石的刻面價格:

  • 0.5 至 1 克拉:每克拉 30-60 美元

  • 1 至 5 克拉:每克拉 150 至 200 美元

  • 超過 5 克拉:每克拉 300 至 3,000 美元

莫桑比克石榴石凸圓形石總是每克拉 5 至 7 美元。 1 克拉以下紅榴石凸圓形寶石的價格範圍為每克拉 4 至 6 美元,1 至 10 克拉時每克拉 5 至 30 美元,超過 10 克拉時最高每克拉 40 美元。

Almandine 雕刻品的價格也更高,起價 450 美元到 84,500 美元。

寶石品質的原始鐵鋁榴石晶體的價格通常為每克拉 0.02 美元至 0.08 美元。

Almandine 保養和維護

幸運的是,鐵鋁榴石的寶石護理很容易!沒有解理和良好的硬度使這塊石頭足夠耐用,適合日常佩戴。不過,您可以選擇在更脆弱的鐵鋁榴石環中進行保護設置,以防止劃傷。

您可以用溫和的肥皂、溫水和軟牙刷輕輕清潔鐵鋁榴石。不要使用機械或蒸汽清潔器。

含有內含物的硬剛玉對極熱更敏感。將寶石存放在遠離其他寶石的陰涼乾燥處。
