About Musgravite Stone

Musgravite is a transparent, captivating gemstone sought after by rare gem enthusiasts. But just how rare is musgravite? 

Firstly, musgravite is even rarer than its parent stone taaffeite, another one of the world’s rarest gemstones. From its debut in 1967 to 2006, there were only 20 faceted musgravite gems identified. Since 2005, there’s only been 8 (known) gem-quality musgravite specimens mined worldwide. 

Given musgravite’s rarity and price points, you may wonder: is musgravite a diamond? No, musgravite is a completely different stone. That said, musgravite’s rarity as a semi-precious gemstone actually exceeds that of the precious gemstone diamond.

Though “musgravite” is the common trade name most use, the official name is actually “magnesiotaaffeite-6N’3S,” sometimes simplified to “magnesiotaaffeite.” 

What about musgravite as a mineral? What are its properties? 

Musgravite Specifications & Characteristics

Musgravite is a beryllium aluminum oxide mineral in the taaffeite, or magnesiotaaffeite, mineral group. Taaffeite and musgravite are tricky to tell apart — even their formulas are quite similar, with BeMg3Al8O16 for taaffeite and Be(Mg,Fe,Zn)2Al6O12 for musgravite.

The musgravite formula can also be written as Mg2BeAl6O12. Though it’s rich in magnesium, it also contains beryllium, aluminum, and oxygen. High amounts of iron and zinc are common, and small amounts of calcium, manganese, and gallium may be present. 

The clearest difference between taaffeite and musgravite is their crystal systems, as taaffeite is hexagonal while musgravite is trigonal. 

As with other minerals containing beryllium, like emerald and aquamarine, musgravite is a hard mineral. It even slightly outranks those beryl stones, sitting at 8 to 8.5 on the Mohs mineral hardness scale (compared to the 7.5 to 8 ranking of beryl varieties). 

What color is musgravite? Musgravite is usually grayish-green to olive, though it can also be found in shades of purple, greenish-blue, or near-colorless. Taaffeite’s color range includes pink, colorless, reddish, and purple. 

The remaining musgravite mineral data is below:

  • Mohs hardness: 8-8.5

  • Color: Usually gray-green, olive green, or grayish-purple; Dark green-blue, shades of violet, gray, colorless

  • Crystal structure: Trigonal

  • Luster: Vitreous (glassy)

  • Transparency: Translucent to transparent

  • Refractive index: 1.719-1.726

  • Density: 3.61–3.68

  • Cleavage: Perfect (or a parting) on [0001], imperfect on [1011]

  • Fracture: Conchoidal

  • Streak: White

  • Luminescence: Usually none, sometimes fluorescence - weak orange in LW-UV, weak red in SW-UV

  • Pleochroism: None

  • Birefringence: 0.007

Moving on from mineralogy, let’s shift gears to look at the metaphysical and historical side of musgravite.

Musgravite Meaning & History

Looking at musgravite symbolism, this crystal represents joy of all kinds. Its predominant green color also represents new beginnings, balance, and personal growth. 

The name “musgravite” comes from the location of its discovery in 1967: the Musgrave Ranges of South Australia. The IMA renamed this Australian gemstone to magnesiotaaffeite-6N’3S because of its magnesium and connection to taaffeite. 

At first, mineralogists believed the stone found in the Musgrave Ranges (specifically at Ernabella Mission) was some sort of taaffeite. After rigorous testing, musgravite was officially described as a new mineral.

As news spread about this new variety, collectors and gemologists started testing stones they’d labeled as taaffeite. However, only two were definitively identified as musgravite between 1993 and 2000. 

Even gemologists at the renowned Gemological Institute of America (GIA), famous for establishing the 4 Cs of diamond grading, hadn’t seen a faceted musgravite until 1997. 

Musgravite in the 21st Century

By 2006, roughly 20 faceted musgravite gems had been confirmed. Canadian gemologist Murray Burford had identified 3 of them. That may seem like a small number, but mathematically, Burford can take credit for identifying 15 percent of the world’s musgravite gems!

After 2005, new discoveries of musgravite (albeit in small amounts) occurred in Sri Lanka, Madagascar, Tanzania, Greenland, and even Antarctica. 

In 2007, huge (pun intended) news hit the gem world when the Gübelin Gem Lab of Switzerland announced the discovery of the largest known musgravite. The grayish-purple stone was a heart-shaped, faceted gem weighing 16.05 carats. It sold for $800,000 in 2021. 

Since 2007, even larger musgravite stones have been found. The current largest known musgravite, called the Ophir Grand Musgravite, is a whopping 214 carats!

Beyond setting world records, what is musgravite used for?

Musgravite Healing Properties

All gems and crystals, including musgravite, can be used as healing stones. Though musgravite isn’t abundant enough for widespread crystal healing use, it still has healing powers — some of which come from its coloring. 

The commonly green musgravite, like other green gemstones, offers emotional balance, connection to nature, and prosperity. Additionally, these gems are great chakra stones for opening the heart chakra, inviting self-love and acceptance. 

Purple hues in musgravite evoke the benefits of purple gemstones, bringing spiritual wisdom and enlightenment.

Gray undertones can even bring out new powers, such as the emotionally stabilizing and concentration-improving inherent to gray gemstones

Other purported healing uses for musgravite include:

  • Stress relief

  • Increasing optimism & positivity

  • Promoting success in all areas (e.g. work, relationships, health)

  • Bringing inner peace

Speaking of inner peace, you may be worried about getting swindled while shopping for a rare (and thus pricey) stone like musgravite. To help you feel at peace while making your decision, we’ll go over the factors of musgravite to keep an eye out for next.

Musgravite Gemstone Properties

In addition to its general rarity, the value of an individual musgravite gem also comes down to its color, cut, clarity, and carat weight. 

Color

Musgravite’s color isn’t the most important factor in its value, but it’s still significant. The stone can be shades of green, violet, or purple, sometimes with gray undertones.

The cause of green hues in musgravite is likely iron in the stone. 

Colorless and red specimens are quite rare, but the most valuable musgravite color is purple. 

Cut

Since musgravite is so rare, almost all stones are faceted to fetch the highest value. Common faceted cuts seen in the few musgravite gems that have been identified are cushion, oval, and pear shapes. 

Clarity

Clarity describes the amount of visible inclusions in a gemstone, which can affect its transparency and sparkle. Transparent, eye-clean (lacking visible inclusions to the naked eye) musgravite stones are the most valuable. 

Some inclusions found in musgravite stones include:

  • Large, rounded apatite crystals

  • Small, colorless needles

  • Opaque, black, hexagonal platelets of graphite

One exceedingly rare musgravite studied by GIA in 2015 displayed thin-film iridescence due to etch tubes aligned with the stone’s crystallography. Though only weighing 0.85 carats, this little gem is the only known musgravite to display any sort of optical phenomenon

Carat Weight

Though much of the musgravite for sale is under 5 carats, there are larger examples. Among the four largest musgravite stones, the American company Ophir Collection LLC owns three. Besides the 16.05-carat stone discussed in the History section, the other three largest musgravite stones currently known are:

  • Ophir Red Musgravite: Largest red musgravite at 21.07 carats

  • Ophir Musgravite: Formerly largest cut musgravite at 22.64 carats

  • Ophir Grand Musgravite: Currently largest cut musgravite at 214 carats

Sizing aside, how does musgravite form in the first place? 

Musgravite Formation & Sources

As a taaffeite variety, musgravite is likely found in similar environments: alluvial deposits, sediments, and sedimentary rocks. What rock is musgravite found in, specifically? 

Since many musgravites are identified from faceted gems, their past is somewhat mysterious. The first discovered musgravite was found near sapphire, spinel, and phlogopite. 

The most recently discovered new deposit (in Greenland) was in a calcite marble within a basement (rocks below a large portion of sedimentary rocks) of gneiss. 

Mining Locations

From its 1967 discovery to 2005, musgravite had only been found in Australia. At present, small quantities of musgravite have also been found in:

  • Antarctica

  • Greenland

  • Madagascar

  • Myanmar

  • Sri Lanka

  • Tanzania

The sources listed above have not produced more than 5-10 musgravite gems annually. 

Given all the factors regarding its rarity discussed thus far, what is musgravite worth?

Musgravite Price & Value

As you might predict, the musgravite price per carat is steep, often steeper than many precious gemstones like diamond. 

Though some are around $6,000 per carat, most faceted musgravite gemstones cost $30,000 to $35,000 per carat. 

However, larger-sized stones could sell for more. For example, the 16.05-carat musgravite gem from Sri Lanka sold for $800,000, making it just over $49,800 per carat.

To put that in perspective, a 1-carat white diamond is generally $1,300 to $16,500, with most falling at $4,400 to $7,600. (Since it’s 1 carat, the price-per-carat is the same as the total price for the stone.) Even tanzanite, known for being among the most expensive gemstones, is only $1,200 per carat on average. 

Before we wrap up, let’s talk about proper gemstone care

Musgravite Care and Maintenance

Though musgravite has good scratch resistance, its perfect cleavage leaves it vulnerable to breaking from hard blows. To prevent that from happening, we recommend protective settings for any jewelry, especially more vulnerable pieces like a musgravite ring. 

Luckily, cleaning musgravite is pretty simple. Being careful not to drop it, you can clean musgravite by gently scrubbing it with a soft toothbrush dipped into a mixture of lukewarm water and mild soap. Once it’s clean, rinse away any soap residue and dry your musgravite with a soft, microfiber cloth. 

We recommend storing your musgravite gemstones separately from other gems to avoid scratches to any stones in your collection. 

Mesmerized by Musgravite? 

Musgravite is a worthy stone to be sought after by rare gem enthusiasts and crystal lovers alike. Though not many gems have been found, this could change in the future. 

As recently as July of 2022, miners found a new deposit in Greenland. Who knows where musgravite may pop up in the future? Only time will tell. For now, we can appreciate this jewel for its beauty and rarity.

綠霞石寶石 Musgravite 是一種在澳大利亞發現的塔菲石寶石品種,以世界上最稀有的寶石之一而聞名。我們甚至將它列入了我們有史以來的十大寶石

不幸的是,對於鄉村流行歌迷來說,musgravite 與 Kacey Musgraves 無關。但是如果你拿到一個罕見的彩虹色標本,你的頭頂上總會掛著一道彩虹!

有興趣尋找一些屬於您自己的 musgravite 首飾嗎?只是想知道更多關於這種許多人所說的“稀有中的稀有”的信息?請繼續關注以了解有關 musgravite 的價格、特性、優勢和歷史的所有信息!

綠霞石寶石

關於鎂重石

Musgravite 是一種透明、迷人的寶石,受到稀有寶石愛好者的追捧。但 musgravite 到底有多稀有?

首先,musgravite 比它的母石taaffeite更稀有,這是世界上另一種最稀有的寶石。從 1967 年首次亮相到 2006 年,僅鑑定出 20 顆刻面的綠霞石寶石。自 2005 年以來,全世界僅開采了 8 個(已知的)寶石級鎂砂礦標本。

鑑於 musgravite 的稀有性和價格點,您可能想知道:musgravite 是鑽石嗎?不,musgravite 是一種完全不同的石頭。也就是說,作為半寶石的musgravite 的稀有性實際上超過了珍貴寶石鑽石。

雖然“musgravite”是最常用的商品名稱,但官方名稱實際上是“magnesiotaaffeite-6N'3S”,有時簡化為“magnesiotaaffeite”。

作為礦物的 musgravite 怎麼樣?它的屬性是什麼?

鎂重石規格和特性

Musgravite 是塔菲石或鎂塔菲石礦物組中的一種鈹鋁氧化物礦物。 Taaffeite 和 musgravite 很難區分 - 即使它們的分子式非常相似,Taaffeite 是 BeMg3Al8O16,而 musgravite 是 Be(Mg,Fe,Zn)2Al6O12。

也可以將 musgravite 公式寫為 Mg2BeAl6O12。雖然它富含鎂,但它還含有鈹、鋁和氧。大量的鐵和鋅是常見的,並且可能存在少量的鈣、錳和鎵。

塔菲石和 musgravite 之間最明顯的區別是它們的晶體系統,因為 taaffeite 是六方的,而 musgravite 是三方的。

與其他含鈹礦物(如祖母綠海藍寶石)一樣,musgravite 是一種堅硬的礦物。它甚至略高於那些綠柱石,在莫氏礦物硬度等級上為 8 至 8.5(與綠柱石品種的 7.5 至 8 等級相比)。

musgravite 是什麼顏色? Musgravite 通常呈灰綠色到橄欖色,但也有紫色、綠藍色或近乎無色的顏色。塔菲石的顏色範圍包括粉紅色、無色、微紅色和紫色。

剩餘的 musgravite 礦物數據如下:

  • 莫氏硬度:8-8.5

  • 顏色:通常為灰綠色、橄欖綠色或灰紫色;深綠藍色、紫色、灰色、無色

  • 晶體結構: 三角

  • 光澤:玻璃狀(玻璃狀)

  • 透明度:半透明到透明

  • 折射率:1.719-1.726

  • 密度: 3.61–3.68

  • 乳溝:在 [0001] 上完美(或分離),在 [1011] 上不完美

  • 斷口: 貝殼狀

  • 條紋:白色

  • 發光:通常無,有時有熒光 - 長波-紫外線中的弱橙色,短波-紫外線中的弱紅色

  • 多色性:無

  • 雙折射:0.007

從礦物學開始,讓我們換個話題,看看 musgravite 的形而上學和歷史方面。

Musgravite 的意義和歷史

從 musgravite 象徵意義來看,這種水晶代表著各種歡樂。它主要的綠色也代表著新的開始、平衡和個人成長。

“musgravite”這個名字來自它於 1967 年發現的地點:南澳大利亞的 Musgrave 山脈。 IMA 將這種澳大利亞寶石重新命名為 magnesiotaaffeite-6N'3S,因為它含有鎂且與塔菲石有關。

起初,礦物學家認為在馬斯格雷夫山脈(特別是在 Ernabella Mission)發現的石頭是某種塔菲石。經過嚴格測試,musgravite 被正式描述為一種新礦物。

隨著有關這一新品種的消息傳開,收藏家和寶石學家開始測試他們標記為塔菲石的寶石。然而,在 1993 年至 2000 年期間,只有兩個被確定為 musgravite。

甚至著名的美國寶石學院 (GIA) 的寶石學家(以建立鑽石分級的 4 C 標準而聞名)直到 1997 年才發現刻面的 musgravite。

21 世紀的慕斯格拉夫特

到 2006 年,已經確認了大約 20 顆刻面的綠霞石寶石。加拿大寶石學家 Murray Burford 鑑定了其中的 3 顆。這似乎是一個很小的數字,但從數學上講,Burford 可以歸功於鑑定了世界上 15% 的紫霞石寶石!

2005 年之後,在斯里蘭卡、馬達加斯加、坦桑尼亞、格陵蘭甚至南極洲都發現了新的綠鎂石(儘管數量很少)。

2007 年,當瑞士古柏林寶石實驗室宣布發現已知最大的 musgravite 時,巨大的(雙關語意)新聞襲擊了寶石界。這顆灰紫色寶石是一顆重達 16.05 克拉的心形多面寶石。它在 2021 年以 80 萬美元的價格售出。

自 2007 年以來,人們發現了更大的 musgravite 石頭。當前已知的最大的 musgravite,稱為 Ophir Grand Musgravite,重達 214 克拉!

除了創造世界紀錄,musgravite 的用途是什麼?

Musgravite 治療特性

所有的寶石和水晶,包括 musgravite,都可以用作治療石。儘管 musgravite 的含量不足以廣泛用於水晶治療,但它仍然具有治療能力——其中一些來自它的顏色。

與其他 綠色寶石一樣,常見的綠色 musgravite 提供情緒平衡、與自然的聯繫和繁榮。此外,這些寶石是很好的脈輪石,可以打開心輪,激發自愛和接納。

musgravite 中的紫色調喚起紫色寶石的好處,帶來精神智慧和啟迪。

灰色底色甚至可以帶來新的力量,例如灰色寶石固有的穩定情緒和提高注意力的作用。

其他聲稱的 musgravite 治療用途包括:

  • 緩解壓力

  • 增加樂觀和積極性

  • 促進所有領域的成功(例如工作、人際關係、健康)

  • 帶來內心的平靜

說到內心的平靜,您可能會擔心在購買像 musgravite 這樣稀有(因此價格昂貴)的石頭時被騙。為了幫助您在做出決定時感到安心,我們將回顧一下 musgravite 的因素,以密切關注下一步。

淺粉色 musgarvite 寶石刻面

白鎢礦寶石特性

除了普遍的稀有性外,每顆閃輝石寶石的價值還取決於其顏色、切工、淨度和克拉重量。

顏色

Musgravite 的顏色不是其價值的最重要因素,但它仍然很重要。石頭可以是綠色、紫色或紫色,有時帶有灰色底色。

musgravite 中綠色色調的原因可能是石頭中的鐵。

無色和紅色的標本非常罕見,但最有價值的顏色是紫色的 musgravite。

由於 musgravite 非常稀有,幾乎所有寶石都經過刻面以獲取最高價值。在少數已鑑定的 musgravite 寶石中常見的刻面切割有枕形、橢圓形和梨形。

明晰

淨度描述了寶石中可見內含物的數量,這會影響其透明度和閃光度。透明、肉眼無暇(沒有肉眼可見的內含物)的鎂橄欖石是最有價值的。

在 musgravite 寶石中發現的一些內含物包括:

  • 大而圓形的磷灰石晶體

  • 無色小針

  • 不透明的黑色六角石墨片

GIA 在 2015 年研究的一種極其稀有的鎢鎂石由於蝕刻管與寶石的晶體學對齊而顯示出薄膜虹彩。這顆小寶石雖然僅重 0.85 克拉,但卻是已知的唯一一種可以顯示任何光學現象的磁鐵礦。

克拉重量

雖然出售的大部分 musgravite 都在 5 克拉以下,但也有更大的例子。在四顆最大的磁鐵礦中,美國公司 Ophir Collection LLC 擁有三顆。除了歷史部分討論的 16.05 克拉寶石外,目前已知的其他三顆最大的磁鐵礦是:

  • Ophir 紅色 musgravite :最大的紅色 musgravite,重 21.07 克拉

  • Ophir Musgravite :以前最大的切工 musgravite,重 22.64 克拉

  • Ophir Grand Musgravite :目前最大的切磨過的 musgravite 重達 214 克拉

除了尺寸,musgravite 首先是如何形成的?

白鎢礦的形成和來源

作為塔菲石的一種,musgravite 可能存在於類似的環境中:沖積礦床、沉積物和沈積岩。具體在什麼岩石中發現了 musgravite?

由於許多 musgravites 是從刻面寶石中鑑定出來的,因此它們的過去有些神秘。最早發現的 musgravite 是在藍寶石尖晶石和金雲母附近發現的。

最近發現的新礦床(在格陵蘭島)位於片麻岩基底(大部分沉積岩下方的岩石)內的方解石大理石中。

採礦地點

從 1967 年發現到 2005 年,musgravite 只在澳大利亞發現過。目前,還發現了少量的musgravite:

  • 南極洲

  • 格陵蘭

  • 馬達加斯加

  • 緬甸

  • 斯里蘭卡

  • 坦桑尼亞

上面列出的來源每年生產的綠鎂石寶石不超過 5-10 顆。

鑑於目前討論的所有關於其稀有性的因素,musgravite 的價值是多少?

Musgravite 價格和價值

正如您所預料的那樣,每克拉的 musgravite 價格非常高,通常比鑽石等許多珍貴寶石的價格還要高。

雖然有些寶石的價格約為每克拉 6,000 美元,但大多數刻面的莫斯重力石寶石的價格為每克拉 30,000 美元至 35,000 美元。

然而,更大尺寸的寶石可以賣得更高。例如,產自斯里蘭卡的 16.05 克拉的 musgravite 寶石以 800,000 美元的價格售出,每克拉僅略高於 49,800 美元。

從這個角度來看,一顆 1 克拉的白鑽一般在 1,300 美元到 16,500 美元之間,大部分跌至 4,400 美元到 7,600 美元之間。 (因為它是 1 克拉,所以每克拉的價格與石頭的總價相同。)即使是以最昂貴的寶石之一而聞名的坦桑石,平均每克拉也只有 1,200 美元。

在我們結束之前,讓我們談談適當的寶石保養

Musgravite 保養和維護

儘管 musgravite 具有良好的抗劃傷性,但其完美的解理使其容易因重擊而斷裂。為防止這種情況發生,我們建議對所有珠寶進行保護性設置,尤其是更易損壞的首飾,如 musgravite 戒指。

幸運的是,清潔 musgravite 非常簡單。小心不要讓它掉落,您可以用柔軟的牙刷蘸取溫水和中性肥皂的混合物輕輕擦洗來清潔 musgravite。清潔後,沖洗掉所有肥皂殘留物,然後用柔軟的超細纖維布擦乾您的 musgravite。

我們建議將您的 musgravite 寶石與其他寶石分開存放,以避免劃傷您收藏中的任何寶石。

被 Musgravite 迷住了?

Musgravite 是一種值得稀有寶石愛好者和水晶愛好者追捧的寶石。雖然發現的寶石不多,但這種情況在未來可能會改變。

就在 2022 年 7 月,礦工們在格陵蘭島發現了一個新礦床。誰知道將來哪裡會出現 musgravite?只有時間會給出答案。現在,我們可以欣賞這顆寶石的美麗稀有。
