"For ages, the Inuit of Greenland have understood the power of tugtupite. Legend has it that lovers can cause the stone to glow fiery red just from the heat of their romance. The brilliance and vibrant colors announce the intensity of their love."
Metaphysical folklore by MinerShop - circa 2003
(During my first two visits to Greenland (2001 and 2002) I learned that, according to local folklore, the name for "tugtupite" originated from "Tutu the reindeer girl" giving birth in the mountains. Her placenta leaked into the rocks, creating tugtupite. That story just didn't seem mystical and inviting, so I revised it to the "romance stone" story above.
This lore took hold and is quoted everywhere.)
Tugtupite was discovered in 1957 close to the town of Narsaq and to-date has only been found in two other areas - Mt. St. Hilaire (Canada) and the Kola Peninsula (Russia). Tugtupite at Kvanefjeld is scattered in irregular hydrothermal veins up to 50cm wide. Only tugtupite from Greenland is deeply colored and valued as a gemstone.
Chemical formula: Na4AlBeSi4O12Cl. Hardness = 6.5, Density = 2.35Tugtupite varies in color from white, pink, to red and crimson. Some blue/white specimens have been recorded. The fluorescence is a brilliant red under short-wave ultraviolet light, and a salmon-red under longwave UV. After exposure to UV (or exposure to sunlight) the red coloration is enhanced (tenebrescense). Tugtupite occurs as irregular forms in whitish albite veins with grey-green lujavrite rock. It can be found throughout the Ilimaussaq Complex, but the specimens from Kvanefjeld are the most sought after - as both jewelry rough and mineral specimens. It is most often found associated with albite, analcime, beryllite, aegirine, neptunite, and pyrochlore. Most often it is massive, very few well developed crystals have been found.
Tugtupite from the Kvanefjeld area is the most widely known fluorescent mineral from Ilimaussaq. It is typically a bright gemmy red and is the source for the gem material used in making beautiful tugtupite cabochons. A typical piece of gem tugtupite will be found in an analcime and lujavrite matrix, often along with aegirine crystals. The natural color ranges from a light pink to a deep cherry red. Under shortwave the red glow is unmistakable. Commonly associated (fluorescent) minerals include chkalovite, beryllite, and sorensenite.
Taseq Tugtupite – Found in veins towards the top of the slopes, this variety of tugtupite is quite different from that found on Kvanefjeld. It consists of a coarse grained pink veining in massive crystals of analcime. Often pieces are associated with aegirine (non FL) and what appears to be a spotty green fluorescent analcime (or remnants of chkalovite). Many pieces have vugs where micro crystals of tugtupite can be found. Daylight color ranges from a light pink to deep pink, This material is also usually quite phosphorescent. It also usually shows a significant color change under midwave UV light.
Tugtupite Crystals – One of our tour members in 2002 found a boulder of tugtupite on the eastern slopes. When he cracked it open he found a cavity of wonderfully formed tugtupite crystals! Since then, many pieces have been found with micro crystals but this piece was truly remarkable in size. Although not a gemmy red, the tugtupite deepened in color to an intense pink. A coating of what appears to be a uranyl activated green FL covered many areas on the specimens, along with a yellowish glow – perhaps from another associated (unknown) mineral.
Kangerlussaq Tugtupite - A gem variety of tugtupite found in the Kangerlussaq Fjord area. Usually associated with polylithionite, chkalovite, and sodalite. Responses vary widely under different wavelengths and is very bright material.
Tugtupite Variations - Tugtupite is found in nearly every locale we visit in the Ilimaussaq Complex. Sometimes it is the primary mineral (and those types are listed below) but often it is found as an accessory to other minerals, or is found in very small quantities, not justifying a "variety" page of tis own.
