English: Labradorite (( Ca,Na)(Al,Si)4O8), a feldspar mineral, is an intermediate to calcic member of the plagioclase series. It is usually defined as having "%An" (anorthite) between 50 and 70. The specific gravity ranges from 2.71 to 2.74. The streak is white, like most silicates. The refractive index ranges from 1.555 to 1.575. Twinning is common. As with all plagioclase members the crystal system is triclinic and three directions of cleavage are present two of which form nearly right angle prisms. It occurs as clear, white to gray, blocky to lath shaped grains in common mafic igneous rocks such as basalt and gabbro, as well as in anorthosites.

Čeština: Labradorit ((Ca,Na)(Al,Si)4O8) je minerál ze skupiny živců. Patří ke skupině plagioklasů a je typický svým mnohobarevným leskem. Obvykle se definuje obsahem anortitu v rozsahu 50 až 70 procent. Charakteristické místo výskytu leží poblíž města Nain v oblasti Labrador v Kanadě, kde ho roku 1770 nalezl a poprvé pojmenoval český misionář, páter Adolf.
Deutsch: Labradorit gilt wie Andesin heute nicht mehr als eigenständiges Mineral, sondern ist eine relativ häufig vorkommende Mineralmischung aus Albit und Anorthit aus der Gruppe der Feldspate und der Mineralklasse der Silikate.
Ελληνικά: Το λαβραδόριο (αγγλ. labradorite) είναι τηκτοπυριτικό ορυκτό της ομάδας των αστρίων, υποομάδας πλαγιοκλάστων. Το όνομά του προέρχεται από την χερσόνησο του Λαμπραντόρ του Καναδά, όπου πρωτοβρέθηκε.
Español: La labradorita o espectrolita es un mineral del grupo de los Silicatos, subgrupo Tectosilicatos y dentro de ellas pertenece a los feldespatos denominados plagioclasas. Es un aluminosilicato de sodio y calcio,
Suomi: Labradoriitti on hauras, paineelle ja hapoille herkkä kivi. Myös lämmönvaihtelut tekevät kiveen rakoja ja halkeamia. Labradoriitin voi sekoittaa ortoklaasiin, enstatiittiin tai amblygoniittiin.
Français : La labradorite, est un minéral du groupe des silicates, subgroupe des tectosilicates de la famille des feldspaths plagioclases. Il s'agit d'une variété d'anorthite (et non d'une espèce reconnue par l'IMA) pour un ratio albite/anorthite de 30/70 à 50/50. La formule chimique est (Na, Ca)(Al, Si)4O8, avec des traces de Fe;K;H2O.
עברית: לברדוריט הוא מינרל טקטוסיליקטי (סיליקטים במבנה מרחבי), השייך לקבוצת המינרלים הידועים בשם פלגיוקלז (סוג של פצלת השדה). מקור השם בחצי האי לברדור שבקנדה שם אותר לראשונה. המינרל מצוי במקומות נוספים בקנדה ובחצי האי הסקנדינבי.
Italiano: La labradorite è un minerale della famiglia dei feldspati plagioclasi con un ratio di albite/anortite che varia da 30/70 a 50/50. Con formula chimica (Na, Ca)(Al, Si)4O8 con tracce: Fe;K;H2O. Nelle sue forme e colorazioni migliori è utilizzato in gioielleria, questi pezzi hanno la particolarità di possedere un gioco di colori dal riflesso metallico normalmente varianti tra il blu e il verde, ma nei pezzi migliori può mostrare tutto lo spettro dei colori.
日本語:ラブラドル長石(ラブラドルちょうせき、labradorite、ラブラドライト)は、曹灰長石(そうかいちょうせき)とも呼ばれる 斜長石の一種。灰長石の[(NaAlSi3O8)50-30(CaAl2Si2O8)50-70]組成相で、独立種ではない。
Lietuvių: Labradoritas silikatų klasės, lauko špatų grupės mineralas. Izomorfinė atmaina nuo natrio - aliuminio silikato iki kalcio - aliuminio silikato (plagioklazas). Labradoritas savo pavadinimą gavo pagal intruzinę magminę uolieną anortozitą, kuris beveik visas sudarytas iš plagioklazų.
Nederlands: Het mineraal labradoriet is een calcium-natrium-aluminium-tectosilicaat met de chemische formule (Ca,Na)(Si,Al)4O8. Het behoort tot de veldspaten.
Norsk bokmål: Labradoritt ((Ca,Na)(Al,Si)4O8), er en feltspat i plagioklas-serien. Plagioklas er en serie ulike kombinasjoner mellom feltspatmineralene albitt og anortitt, og utgjør en hovedgruppe ved siden av alkalifeltspat. Labradoritt består av 50-30% albitt og 50-70% anortitt. Den har et krystallsystem som er triklint. Som de fleste silikater er strekfargen hvit. Labradoritt forekommer i magmatiske bergarter som gabbro, basalt og anortositt. Labradoritt har sitt navn etter Labrador i Canada.
Português: Labradorite ((Ca,Na)(Al,Si)4O8), é um mineral do grupo dos feldspatos, sendo um dos membros cálcicos intermédios da série da plagioclase. Define-se geralmente como tendo "%An" (anortite) entre 50 e 70. O peso específico varia de 2.71 a 2.74. O indíce de refracção varia de 1.555 a 1.575. São frequentes os cristais maclados. Tal como todos os membros da série da plagioclase, cristaliza no sistema triclínico e possui três direcções de clivagem duas das quais formam prismas quase rectos.
Русский: Лабрадорит — основная горная порода, разновидность анортозита. Состоит преимущественно из плагиоклаза — лабрадора с незначительной примесью (не более 5—7 %) пироксенов и рудных минералов. Назван по месту первой находки — на полуострове Лабрадор в Северной Америке.
Simple English: Labradorite is one kind of feldspar. It is a silicate mineral, and is special because it is often pretty enough to be used in jewelry. Some kinds of labradorite are called moonstone or sunstone.
Slovenčina: Labradorit je triklinický minerál plagioklasového radu (teda sodno vápenatý živec) tvoriaci tuhý roztok medzi albitom a anortitom. V tomto rade sa nachádza bližšie k anortitu, je typický hrou farieb na povrchu. Možno ho často nájsť v gabrách a bazaltoch. Pomerne často vytvára monominerálne horniny tzv. anortozity. Názov minerálu je odvodený od Labradoru, oblasti na atlantickom pobreží Kanady, kde sa nachádzajú ložiská hrubozrnného masívneho labradoritu s charakteristickou hrou farieb. Tvorí bázickú vyvretú horninu anortozit.
