In 1901 his countryman Leonhard Borgström described it from the Tawa Valley on Russia's Kola Peninsula and named it in Hackman's honour. This piece comes from Badakhshan Province in northeastern Afghanistan, which has produced significant gem-quality hackmanite in recent decades (GIA, 2009). Mindat records world-class crystals from Ladjuar Medam, near the Sar-e-Sang lapis lazuli mines.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eHackmanite is a sulfur-bearing variety of sodalite known for tenebrescence (reversible photochromism). Exposure to ultraviolet light deepens its colour to pink, violet or purple; ordinary white light or daylight then gradually fades it back to its paler colour. Under longwave UV it also fluoresces orange. How each piece behaves in the dark varies with origin: some hold their colour, some slowly fade, and some Badakhshan material is noted to re-darken. The effect is reversible but can be permanently destroyed by strong heat.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eLike other sodalite varieties, hackmanite fluoresces a bright orange under UV light. What makes it special among fluorescent sodalites is the combination of that fluorescence with tenebrescence.\u003c\/p\u003e\n\u003cp\u003eThe combination of Tenebrescence and fluorescence in these specimens is truly a sight to behold - they start off pale purple, fluoresce safety orange under UV, and then, when the UV light is removed, they turn a deep dark purple in sharp contrast to their original color.\u003c\/p\u003e\n\u003cp\u003eIn crystal traditions, hackmanite is associated with the third eye chakra, intuition and insight, and with calm and positive thinking.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChemical Composition\u003c\/strong\u003e: Na8(Al6Si6O24)(Cl2,S)\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\" class=\"p1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eChakra\u003c\/b\u003e: Third Eye\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\" class=\"p1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eMini\u003cbr\u003eApproximate Size of 1 Piece: \u003c\/b\u003e1cm x 1cm x 1cm\u003cb data-mce-fragment=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003eApproximate Weight of 1 Piece: \u003c\/b\u003e0.5g\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\" class=\"p1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eSmall\u003cbr\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 1.75cm x 1.25cm x 1.25cm\u003cb data-mce-fragment=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb data-mce-fragment=\"1\"\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 3g\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\" class=\"p1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eMedium\u003cbr data-mce-fragment=\"1\"\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 2.5cm x 1.5cm x 1.5cm\u003cb data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb data-mce-fragment=\"1\"\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 5g\u003cbr\u003e\u003cbr\u003e\u003cb data-mce-fragment=\"1\"\u003eLarge\u003cbr data-mce-fragment=\"1\"\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 2.5cm x 2cm x 2cm\u003cb data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb data-mce-fragment=\"1\"\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 7g\u003cbr\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\" class=\"p1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eX-Large\u003cbr data-mce-fragment=\"1\"\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 3.25cm x 2.5cm x 2cm\u003cb data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb data-mce-fragment=\"1\"\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 10g\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\" class=\"p1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eXX-Large\u003cbr data-mce-fragment=\"1\"\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 3.75cm x 3cm x 2cm\u003cb data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb data-mce-fragment=\"1\"\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 18g\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\" class=\"p1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eXXX-Large\u003cbr data-mce-fragment=\"1\"\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 4.5cm x 4.5cm x 2.5cm\u003cb data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb data-mce-fragment=\"1\"\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 42g \u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\" class=\"p1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eQuantity\u003c\/strong\u003e:\u003cstrong data-mce-fragment=\"1\"\u003e \u003c\/strong\u003e1pc\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\" class=\"p1\"\u003e\u003cem\u003eWe do our best to buy quality products- although not every rock is the same.
