tugtupite gemstoneTugtupite is a commonly mottled gemstone with predominant red or pink hues. It’s mainly found in Greenland and has the nickname “Reindeer Stone.”

Is tugtupite rare? Yes. It’s a fairly rare mineral and extremely rare faceted gem. It’s better known among collectors.

That said, tugtupite has fascinating properties like piezoelectricity, fluorescence, and tenebrescence — all of which we’ll break down in this guide.

Come along as we uncover the secrets behind tugtupite gemstone benefits, prices, history, and more!

What Is A Tugtupite Stone?

Tugtupite is a recently discovered semi-precious gemstone, only known since the 1960s. The rare stone was discovered in Greenland, where it’s also called Tuktu meaning “reindeer blood,” derived from the Greenlandic Inuit word tuttu for “reindeer.”

Astrologically, tugtupite benefits Leo signs.

The stone may resemble gems like rhodochrosite and rhodonite when it has pink and white or pink and black banding, respectively. However, rhodochrosite is a manganese silicate, rhodonite is a manganese carbonate, and tugtupite doesn’t contain manganese.

Though they may look different, tugtupite and sodalite are more closely related and often grow together.

Scientists have created synthetic tugtupite for research into how different sodalite-group minerals luminesce, but synthetic tugtupite hasn’t been made for gemstone use.

Tugtupite Specifications & Characteristics

Tugtupite is a beryllium aluminum tectosilicate containing chlorine and sodium. The mineral’s formula is Na4AlBeSi4O12Cl. Common impurities include iron, gallium, sulfur, magnesium, potassium, calcium, and water.

The mineral may be classified in the feldspathoid mineral group of tectosilicates similar to feldspars but with less silica and different structures. Other feldspathoids include afghanite, petalite, and sodalite-group minerals.

More specifically, tugtupite is part of the helvine mineral group, sometimes considered a subgroup of sodalite.

The crystal habits of tugtupite include short prisms with sphenoids (four-faced, wedge-shaped, closed form) or pyramids, masses, and fine-grained aggregates. Crystals may exhibit penetration twinning, creating pseudocubic triplets, or pseudo-trigonal contact twinning.

Tugtupite Optical Properties

As mentioned earlier, tugtupite has some stunning properties.

For one, it displays strong fluorescence (glow under X-rays or UV-light) and phosphorescence (longer glow, like “glow-in-the-dark” materials). Some even call it the “king of fluorescent minerals.”

But most impressive is tugtupite’s tenebrescence, or “reversible photochromism.”

Tenebrescence, the rarest type of optical phenomenon in gemstones, is when a stone changes colors after being exposed to certain types of light (usually UV-light like sunlight) then goes back to its original color. This shift can happen repeatedly without permanently affecting the stone’s coloring.

Unlike color-changing gems, tenebrescent gems gradually shift colors when coming in and out of the different lights.

So, warmth and UV-light exposure (like sunlight) will make tugtupite’s color more intense, often from light pink to bright scarlet red.

The only other gems that can be tenebrescent are scapolite (rarely), spodumene, and the sodalite variety hackmanite.

Here are all of tugtupite’s properties listed:

  • Mohs hardness: 4-6.5

  • Color: Commonly white, pink, rose-red, crimson, green; Rarely blue; Mottling is common

  • Crystal structure: Tetragonal

  • Luster: Vitreous, sub-vitreous, waxy, dull, or greasy

  • Transparency: Translucent to opaque

  • Refractive index: 1.496-1.502

  • Density: 2.11-2.60

  • Cleavage: Distinct/good on {101}; Fair on {110}

  • Fracture: Irregular/uneven or conchoidal

  • Streak: White

  • Luminescence: Fluorescence present - distinct rose-red stronger in SW-UV than LW-UV or salmon-red in SW-UV & orange in LW-UV; Phosphorescence present - bright cream to orange-cream or dull red to cream-white; X-rays - darkens paler colors

  • Pleochroism: Present, weak to strong - bluish-red to orange-red or lilac to red-orange

  • Birefringence: 0.006-0.008; Anomalously biaxial

  • Dispersion: 0.012

  • Optical phenomena: Tenebrescence

What about tugtupite’s metaphysical properties and meaning?

Tugtupite Meaning & History

Tugtupite stones symbolize optimism, harmony, and love. Some interpret the tugtupite spiritual meaning as igniting passion or love you’d once lost or forgotten.

The stone’s ability to become a stronger color in the sunlight but fade in the dark can serve as a reminder to let your inner light shine.

In Greenland, tugtupite has inspired many legends, most prominently the story of Tutu:

The Inuit legend goes that Tutu, the “reindeer girl,” traveled up the mountains to give birth to her first child. During the delivery, the blood that came out went into the mountain stones, creating tugtupite.

History

Tugtupite was first discovered by Danish mineralogist Henning Sørensen in Tugtup Agtâkorfia, Greenland, in 1957. The mineral was found in an area called the Ilimaussaq complex, the same area where European explorers first found sodalite in 1811. Besides sodalite, it’s also the type locality for many other minerals including arfvedsonite and eudialyte.

The name "tugtupite" derives from this first locale, and Tugtup, meaning “reindeer” in Greenlandic Inuit, inspiring the nickname “Reindeer Stone.” The stone’s red coloring, resembling the famous red nose of the reindeer Rudolph, may also contribute to this nickname.

However, the first name for the stone was beryllium sodalite. Russian mineralogists Evgeny Ivanovich Semenov and Alexandra Vasilyevna Bykova published their discovery of tugtupite in Russia in 1960. Wider interest in the stone only came when it was discovered in another area in Greenland in 1962.

Sørensen proposed the name “tugtupite” in 1963, which was approved by the International Mineralogical Association (IMA) in 1965. The first tugtupite gemstones were made available in 1965 as well.

Like nuummite, tugtupite’s only abundant gemstone source is Greenland. Unfortunately, the stone has become significantly rarer since its initial discovery.

Back to the metaphysical side, what are the healing properties of tugtupite crystals?

Tugtupite Healing Properties

As a predominantly pink healing stone, tugtupite joins other pink gemstones in bringing acceptance and love, along with being heart chakra stones.

What does tugtupite do for you physically?

Physical Healing

Physically, tugtupite crystals are said to help with:

  • Hormone balance

  • Infertility

  • Blood circulation

  • Heart health

Emotional Healing

Emotionally, tugtupite benefits those dealing with cynicism or negativity, especially stemming from past hardships or betrayals. The crystal is believed to help you open yourself to love after heartbreak while helping you love yourself again.

Tugtupite Gemstone Properties

Besides rarity, tugtupite gemstone value depends on color, cut, clarity, transparency, and carat weight.

Color

The common pink colors in tugtupite gems are caused by sulfur-bearing color centers. Typically mottled, other colors in tugtupite include black, white, and sometimes green. Blue colors are rare, with likely fewer than a dozen blue tugtupite cabochons ever being cut.

Stones with more red to pink coloring than white or black are generally more valuable.

Among collectors, strong pleochroism, tenebrescence, and luminescence are also important.

Cut

Most often, tugtupite is cut into cabochons, carved, or sold uncut (rough). Faceted tugtupite gems are extremely rare and valuable.

Clarity & Transparency

Clarity is the degree of visible inclusions in a gem, which can lower the gem's transparency and value. Tugtupite specimens are usually included, often with yellow spots or black needles. Fewer inclusions and higher translucence mean higher value.

Carat Weight & Size

There have only been a few faceted tugtupites, all small (1-2 cts) and not entirely inclusion-free. Most translucent tugtupites become cabochons, and larger specimens are often cut (or sold rough) for ornamental pieces.

Tugtupite Formation & Sources

Tugtupite forms in hydrothermal veins within intrusive igneous rocks, primarily nepheline syenite pegmatites. Sodalite-group minerals typically crystallize from sodium-rich magma inside igneous rocks as the rocks form.

Tugtupite can also form by replacing the sodium beryllium silicate chkalovite.

Associated minerals found with tugtupite include:

Mining Locations

Nearly all gem-quality tugtupites come from the Taseq and Kvanefield areas of Greenland. The only additional known sources are Canada and Russia.

Part of tugtupite’s rarity is how difficult it is to mine in Greenland. Miners must travel by boat and on foot to high mountains, carrying the material back in bags.

Tugtupite Price & Value

With such a rare gem, you can expect fairly high prices while browsing tugtupite for sale — though still lower than many precious gems.

Though some lower-quality faceted tugtupites can be found for around $30-$40 per carat, most are about $270-$480 per carat or higher.

Tugtupite cabochons range from around $8-$240 per carat, though most are around $20 per carat.

Pink tugtupite cabochon pendants cost between about $100 to $2,200, though rough pendants are usually $30 to $100. Tugtupite rings are generally $200 to $500. Earrings are around $200 to $250.

Lastly, we’ll go over tugtupite gemstone care.

Tugtupite Care and Maintenance

Given the stone’s low Mohs hardness and distinct cleavage, tugtupite jewelry can be fragile. We recommend opting for pendants and earrings — only wear tugtupite rings with protective settings.

Clean tugtupite with mild soap, warm water, and a soft toothbrush. Don’t use mechanical cleaning systems. Store it separately from other gems to avoid scratches.

Tugtupite 是一種常見的斑駁寶石,主要呈紅色或粉紅色調。主要產於格陵蘭島,有“馴鹿石”的別稱。

tugtupite稀有嗎?是的。這是一種相當稀有的礦物,也是極其稀有的刻面寶石。它在收藏家中更為人所知。

也就是說,tugtupite 具有令人著迷的特性,例如壓電性、熒光性和變性——我們將在本指南中詳細介紹所有這些特性。

一起來揭開 tugtupite 寶石優勢、價格、歷史等背後的秘密吧!

什麼是 Tugtupite 石頭?

Tugtupite 是一種最近發現的半寶石,自 1960 年代才為人所知。這種稀有寶石是在格陵蘭島發現的,在那裡它也被稱為 Tuktu,意思是“馴鹿血”,源自格陵蘭因紐特語中的“馴鹿”一詞。

占星學上,tugtupite 有利於獅子座標誌。

當寶石分別具有粉紅色和白色或粉紅色和黑色條紋時,可能類似於菱錳礦和薔薇輝石等寶石。但是,菱錳礦是一種矽酸錳,菱錳礦是一種碳酸錳,而菱錳礦不含錳。

雖然它們可能看起來不同,但 tugtupite 和方鈉石的關係更為密切,並且經常一起生長。

科學家們創造了合成tugtupite 用於研究不同方鈉石族礦物如何發光,但合成 tugtupite 尚未用於寶石用途。

Tugtupite 規格和特性

Tugtupite 是一種含有氯和鈉的鈹鋁構造矽酸鹽。該礦物的分子式為 Na4AlBeSi4O12Cl。常見的雜質包括鐵、鎵、、鎂、鉀、鈣和水。

該礦物可歸類為類似於長石的構造矽酸鹽類長石礦物組,但二氧化矽含量較少且結構不同。其他長石包括阿富汗石透長石和方鈉石族礦物。

更具體地說,tugtupite 是 helvine 礦物組的一部分,有時被認為是方鈉石的一個子組。

tugtupite 的晶體習性包括帶蝶骨(四面、楔形、閉合形式)或金字塔的短棱柱、團塊和細粒集合體。晶體可能表現出穿透孿晶,產生偽立方三胞胎或偽三角接觸孿晶。

tugtupite光學性質

如前所述,tugtupite 具有一些驚人的特性。

一方面,它顯示出強烈的熒光(在 X 射線或紫外線下發光)和磷光(發光時間更長,如“夜光”材料)。有人甚至稱其為“熒光礦物之王”。

但最令人印象深刻的是 tugtupite 的變暗現象,或“可逆光致變色”。

老化現像是寶石中最罕見的一種光學現象,是指寶石在暴露於特定類型的光(通常是太陽光等紫外線)後顏色發生變化,然後又恢復到原來的顏色。這種轉變可以反復發生,而不會永久影響寶石的顏色。

變色寶石不同,暗光寶石在進出不同光線時會逐漸改變顏色。

因此,溫暖和紫外線照射(如陽光)會使 tugtupite 的顏色更濃,通常從淡粉色到鮮紅色。

其他唯一可以呈暗黃光的寶石是方柱石(很少見)、鋰輝石和方鈉石品種hackmanite

以下列出了 tugtupite 的所有屬性:

  • 莫氏硬度:4-6.5

  • 顏色:常見的有白色、粉紅色、玫紅色、深紅色、綠色;很少是藍色的;斑點很常見

  • 晶體結構: 四方

  • 光澤:玻璃質、亞玻璃質、蠟質、暗淡或油膩

  • 透明度: 半透明到不透明

  • 折射率:1.496-1.502

  • 密度:2.11-2.60

  • 乳溝:{101} 明顯/良好;公平於{110}

  • 斷口:不規則/不均勻或貝殼狀

  • 條紋:白色

  • 發光:存在熒光 - 獨特的玫瑰紅色在短波-紫外線中比長波-紫外線更強,或在短波-紫外線中呈鮭魚紅色,在長波-紫外線中呈橙色;存在磷光 - 亮奶油色至橙色奶油色或暗紅色至奶油白色; X 射線 - 使顏色變暗

  • 多色性:存在,弱到強 - 藍紅色到橙紅色或淡紫色到橙紅色

  • 雙折射:0.006-0.008;異常雙軸

  • 色散:0.012

  • 光學現象:衰老

tugtupite 的形而上學屬性和意義如何?

Tugtupite 意義和歷史

tugtupite 石頭像徵著樂觀、和諧和愛。有些人將 tugtupite 的精神意義解釋為點燃你曾經失去或遺忘的激情或愛。

石頭在陽光下顏色更深但在黑暗中褪色的能力可以提醒您讓內在的光芒閃耀。

在格陵蘭島,tugtupite 激發了許多傳說,最突出的是圖圖的故事:

因紐特人傳說“馴鹿女孩”圖圖上山生下了她的第一個孩子。在分娩過程中,流出的血液進入山石中,形成了 tugtupite。

歷史

Tugtupite 於 1957 年由丹麥礦物學家 Henning Sørensen 在格陵蘭島的 Tugtup Agtâkorfia 首次發現。該礦物發現於一個名為 Ilimaussaq complex 的地區,歐洲探險家於 1811 年在同一地區首次發現方鈉石。除了方鈉石外,它也是模式產地對於許多其他礦物,包括arfvedsoniteeudialyte

“tugtupite”這個名字來源於第一個語言環境和Tugtup ,在格陵蘭因紐特語中意為“馴鹿”,因此獲得了“馴鹿石”的綽號。石頭的紅色,類似於著名的馴鹿魯道夫的紅鼻子,也可能有助於這個綽號。

然而,這塊石頭的第一個名字是鈹方鈉石。俄羅斯礦物學家 Evgeny Ivanovich Semenov 和 Alexandra Vasilyevna Bykova 於 1960 年公佈了他們在俄羅斯發現的 tugtupite。直到 1962 年在格陵蘭島的另一個地區發現這種石頭時,人們才對它產生了更廣泛的興趣。

Sørensen 於 1963 年提出“tugtupite”這個名稱,並於 1965 年獲得國際礦物學協會 (IMA) 的批准。第一批 tugtupite 寶石也於 1965 年問世。

nuummite一樣,tugtupite 唯一豐富的寶石產地是格陵蘭島。不幸的是,自最初發現以來,這塊石頭變得非常稀有。

回到形而上學的方面,tugtupite 晶體的治療特性是什麼?

Tugtupite 寶石特性

除了稀有性,tugtupite 寶石的價值還取決於顏色、切工、淨度、透明度和克拉重量。

顏色

tugtupite 寶石中常見的粉紅色是由含硫色心造成的。 tugtupite 通常帶有斑點,其他顏色包括黑色、白色,有時還有綠色。藍色很少見,可能只有不到一打的藍色凸圓寶石被切磨過。

與白色或黑色相比,紅色到粉紅色更多的寶石通常更有價值。

在收藏家中,強烈的多色性、變暗和發光也很重要。

大多數情況下,tugtupite 被切割成凸圓形、雕刻或未切割(粗糙)出售。 刻面tugtupite 寶石極為稀有且價值不菲。

清晰透明

淨度是寶石中可見內含物的程度,它會降低寶石的透明度和價值。通常包括 tugtupite 標本,通常帶有黃色斑點或黑色針狀物。更少的內含物和更高的半透明度意味著更高的價值。

克拉重量和尺寸

只有幾個刻面的 tugtupites,都是小的(1-2 克拉)並且並非完全不含內含物。大多數半透明的 tugtupites 變成凸圓形,較大的標本通常被切割(或出售)作為裝飾品。

Tugtupite 的形成和來源

Tugtupite 在侵入火成岩內的熱液脈中形成,主要是霞石正長偉晶岩。方鈉石族礦物通常在岩石形成時從火成岩內部富含鈉的岩漿中結晶出來。

Tugtupite 也可以通過取代鈉鈹矽酸鹽 chkalovite 形成。

與 tugtupite 一起發現的相關礦物包括:

採礦地點

幾乎所有寶石級的 tugtupites 都來自格陵蘭島的 Taseq 和 Kvanefield 地區。唯一已知的其他來源是加拿大和俄羅斯。

tugtupite 的稀有性部分是因為在格陵蘭開採是多麼困難。礦工們必須乘船和步行前往高山,將材料裝在袋子裡運回去。

Tugtupite 價格和價值

擁有如此稀有的寶石,您可以在瀏覽待售的 tugtupite 時預期相當高的價格——儘管仍低於許多珍貴寶石。

雖然一些質量較低的刻面 tugtupites 的價格約為每克拉 30-40 美元,但大多數價格約為每克拉 270-480 美元或更高。

Tugtupite 凸圓形寶石的價格從每克拉 8 美元到 240 美元不等,但大多數價格在每克拉 20 美元左右。

粉紅色 tugtupite 凸圓形吊墜的價格在 100 美元到 2,200 美元之間,但原石吊墜的價格通常為 30 美元到 100 美元。 Tugtupite 戒指的價格通常為 200 到 500 美元。耳環的價格在 200 到 250 美元之間。

最後,我們將討論 tugtupite 寶石護理

Tugtupite 保養和維護

鑑於這種石頭的低莫氏硬度和明顯的解理,tugtupite 首飾可能很脆弱。我們建議選擇吊墜和耳環——只佩戴帶有保護裝置的tugtupite 戒指。

用溫和的肥皂、溫水和軟牙刷清潔 tugtupite。不要使用機械清潔系統。將其與其他寶石分開存放,以免劃傷。
