We return to the lands of the far north again for another design using gemstones from Labrador and Norway..
This specific design incorporates Labradorite rectangles from Labrador and Larvakite rounds from Norway. They are intersperced with clear crystal and silver beads. Earrings using matching gemstones and crystals complete the set.
.
Labradorite is a feldspara intermediate to calcic member of the plagioclase series. Streak seen within the stone is white, like most silicates. 
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. Labradorite occurs as a nearly clear, white to grey rocky to lath grained rock. Labradorite is found on Paul's Island near the town of Nain in Labrador, Canada. It occurs in large crystal masses in anorthosite and shows a play of colors called labradorescence. The labradorescence, or schiller effect, is the result of light refracting within lamellar intergrowths resulting from phase exsolution on colling in the Boggild miscibility gap. 
Gemstone varieties of labradorite exhibiting a high degree of labradorescence are called Spectrolite: Moonstone and Sunstone are also commonly used terms, and high-quality samples with good qualities are desired for jewelry.

Larvakite is a variety of Labradorite that comes from Norway. Larvakite originates from the town of Larvik in Norway, where this specific type of igneous rock is found. The crystallisation of this ternary feldspar indicates that Larvakite began to crystallise under lower crustal conditions than did Labradorite. Larvakite posses the same labradoresence characteristics as Labradorite and the two can eaasily be confused.
