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.

什么是 Tugtupite 石头?

Tugtupite 是一种最近发现的半宝石,自 1960 年代才为人所知。这种稀有宝石是在格陵兰岛发现的,在那里它也被称为 Tuktu,意思是“驯鹿血”,源自格陵兰因纽特语中的“驯鹿”一词。

占星学上,tugtupite 有利于狮子座标志。

当宝石分别具有粉红色和白色或粉红色和黑色条纹时,可能类似于菱锰矿和蔷薇辉石等宝石。但是,菱锰矿是一种硅酸锰,菱锰矿是一种碳酸锰,而菱锰矿不含锰。

虽然它们可能看起来不同,但 tugtupite 和方钠石的关系更为密切,并且经常一起生长。

科学家们创造了合成tugtupite 用于研究不同方钠石族矿物如何发光,但合成 tugtupite 尚未用于宝石用途。

Tugtupite 规格和特性

Tugtupite 是一种含有氯和钠的铍铝构造硅酸盐。该矿物的分子式为 Na4AlBeSi4O12Cl。常见的杂质包括铁、镓、、镁、钾、钙和水。

该矿物可归类为类似于长石的构造硅酸盐类长石矿物组,但二氧化硅含量较少且结构不同。其他长石包括阿富汗石透长石和方钠石族矿物。

更具体地说,tugtupite 是 helvine 矿物组的一部分,有时被认为是方钠石的一个子组。

tugtupite 的晶体习性包括带蝶骨(四面、楔形、闭合形式)或金字塔的短棱柱、团块和细粒集合体。晶体可能表现出穿透孪晶,产生伪立方三胞胎或伪三角接触孪晶。

tugtupite光学性质

如前所述,tugtupite 具有一些惊人的特性。

一方面,它显示出强烈的荧光(在 X 射线或紫外线下发光)和磷光(发光时间更长,如“夜光”材料)。有人甚至称其为“荧光矿物之王”。

但最令人印象深刻的是 tugtupite 的变暗现象,或“可逆光致变色”。

老化现象是宝石中最罕见的一种光学现象,是指宝石在暴露于特定类型的光(通常是太阳光等紫外线)后颜色发生变化,然后又恢复到原来的颜色。这种转变可以反复发生,而不会永久影响宝石的颜色。

变色宝石不同,暗光宝石在进出不同光线时会逐渐改变颜色。

因此,温暖和紫外线照射(如阳光)会使 tugtupite 的颜色更浓,通常从淡粉色到鲜红色。

其他唯一可以呈暗黄光的宝石是方柱石(很少见)、锂辉石和方钠石品种hackmanite

以下列出了 tugtupite 的所有属性:

  • 莫氏硬度:4-6.5

  • 颜色:常见的有白色、粉红色、玫红色、深红色、绿色;很少是蓝色的;斑点很常见

  • 晶体结构: 四方

  • 光泽:玻璃质、亚玻璃质、蜡质、暗淡或油腻

  • 透明度: 半透明到不透明

  • 折射率:1.496-1.502

  • 密度:2.11-2.60

  • 乳沟:{101} 明显/良好;公平于{110}

  • 断口:不规则/不均匀或贝壳状

  • 条纹:白色

  • 发光:存在荧光 - 独特的玫瑰红色在短波-紫外线中比长波-紫外线更强,或在短波-紫外线中呈鲑鱼红色,在长波-紫外线中呈橙色;存在磷光 - 亮奶油色至橙色奶油色或暗红色至奶油白色; X 射线 - 使颜色变暗

  • 多色性:存在,弱到强 - 蓝红色到橙红色或淡紫色到橙红色

  • 双折射:0.006-0.008;异常双轴

  • 色散:0.012

  • 光学现象:衰老

tugtupite 的形而上学属性和意义如何?

Tugtupite 意义和历史

tugtupite 石头象征着乐观、和谐和爱。有些人将 tugtupite 的精神意义解释为点燃你曾经失去或遗忘的激情或爱。

石头在阳光下颜色更深但在黑暗中褪色的能力可以提醒您让内在的光芒闪耀。

在格陵兰岛,tugtupite 激发了许多传说,最突出的是图图的故事:

因纽特人传说“驯鹿女孩”图图上山生下了她的第一个孩子。在分娩过程中,流出的血液进入山石中,形成了 tugtupite。

历史

Tugtupite 于 1957 年由丹麦矿物学家 Henning Sørensen 在格陵兰岛的 Tugtup Agtâkorfia 首次发现。该矿物发现于一个名为 Ilimaussaq complex 的地区,欧洲探险家于 1811 年在同一地区首次发现方钠石。除了方钠石外,它也是模式产地对于许多其他矿物,包括arfvedsoniteeudialyte

“tugtupite”这个名字来源于第一个语言环境和Tugtup ,在格陵兰因纽特语中意为“驯鹿”,因此获得了“驯鹿石”的绰号。石头的红色,类似于著名的驯鹿鲁道夫的红鼻子,也可能有助于这个绰号。

然而,这块石头的第一个名字是铍方钠石。俄罗斯矿物学家 Evgeny Ivanovich Semenov 和 Alexandra Vasilyevna Bykova 于 1960 年公布了他们在俄罗斯发现的 tugtupite。直到 1962 年在格陵兰岛的另一个地区发现这种石头时,人们才对它产生了更广泛的兴趣。

Sørensen 于 1963 年提出“tugtupite”这个名称,并于 1965 年获得国际矿物学协会 (IMA) 的批准。第一批 tugtupite 宝石也于 1965 年问世。

nuummite一样,tugtupite 唯一丰富的宝石产地是格陵兰岛。不幸的是,自最初发现以来,这块石头变得非常稀有。

Tugtupite 宝石特性

除了稀有性,tugtupite 宝石的价值还取决于颜色、切工、净度、透明度和克拉重量。

颜色

tugtupite 宝石中常见的粉红色是由含硫色心造成的。 tugtupite 通常带有斑点,其他颜色包括黑色、白色,有时还有绿色。蓝色很少见,可能只有不到一打的蓝色凸圆宝石被切磨过。

与白色或黑色相比,红色到粉红色更多的宝石通常更有价值。

在收藏家中,强烈的多色性、变暗和发光也很重要。

大多数情况下,tugtupite 被切割成凸圆形、雕刻或未切割(粗糙)出售。 刻面tugtupite 宝石极为稀有且价值不菲。

清晰透明

净度是宝石中可见内含物的程度,它会降低宝石的透明度和价值。通常包括 tugtupite 标本,通常带有黄色斑点或黑色针状物。更少的内含物和更高的半透明度意味着更高的价值。

克拉重量和尺寸

只有几个刻面的 tugtupites,都是小的(1-2 克拉)并且并非完全不含内含物。大多数半透明的 tugtupites 变成凸圆形,较大的标本通常被切割(或出售)作为装饰品。

Tugtupite 的形成和来源

Tugtupite 在侵入火成岩内的热液脉中形成,主要是霞石正长伟晶岩。方钠石族矿物通常在岩石形成时从火成岩内部富含钠的岩浆中结晶出来。

Tugtupite 也可以通过取代钠铍硅酸盐 chkalovite 形成。

与 tugtupite 一起发现的相关矿物包括:

采矿地点

几乎所有宝石级的 tugtupites 都来自格陵兰岛的 Taseq 和 Kvanefield 地区。唯一已知的其他来源是加拿大和俄罗斯。

tugtupite 的稀有性部分是因为在格陵兰开采是多么困难。矿工们必须乘船和步行前往高山,将材料装在袋子里运回去。

Tugtupite 价格和价值

拥有如此稀有的宝石,您可以在浏览待售的 tugtupite 时预期相当高的价格——尽管仍低于许多珍贵宝石。

虽然一些质量较低的刻面 tugtupites 的价格约为每克拉 30-40 美元,但大多数价格约为每克拉 270-480 美元或更高。

Tugtupite 凸圆形宝石的价格从每克拉 8 美元到 240 美元不等,但大多数价格在每克拉 20 美元左右。

粉红色 tugtupite 凸圆形吊坠的价格在 100 美元到 2,200 美元之间,但原石吊坠的价格通常为 30 美元到 100 美元。 Tugtupite 戒指的价格通常为 200 到 500 美元。耳环的价格在 200 到 250 美元之间。

最后,我们将讨论 tugtupite 宝石护理

Tugtupite 保养和维护

鉴于这种石头的低莫氏硬度和明显的解理,tugtupite 首饰可能很脆弱。我们建议选择吊坠和耳环——只佩戴带有保护装置的tugtupite 戒指。

用温和的肥皂、温水和软牙刷清洁 tugtupite。不要使用机械清洁系统。将其与其他宝石分开存放,以免划伤。
