Character Grade means the stone did not fully transform into jade: each piece ranges from about 10% nephrite up to 90% or even 100%, with the rest made up of the surrounding, less-transformed host rock. That mix gives every tumble its own blend of colour and texture, from deep and mottled greens to pale, speckled and white patches.\u003c\/p\u003e\n\u003cp\u003eThese pieces typically come from a section or the outer rim of a Northern British Columbia nephrite boulder, cut down and run through mass tumbling to a smooth polish. No two are alike, which makes them a favourite with collectors who enjoy seeing how jade forms in the ground.\u003c\/p\u003e\n\u003cp\u003eNephrite is a tough, interlocking mass of fibrous amphibole crystals, which makes it exceptionally durable and noticeably heavy in the hand. British Columbia is one of the world's major sources of green nephrite jade.\u003c\/p\u003e\n\u003cp\u003eJade has been valued for thousands of years in many cultures, including China, Central America and New Zealand, where it is traditionally seen as a symbol of beauty, good fortune and protection. These associations come from cultural traditions rather than scientifically established properties.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eChemical Composition\u003c\/b\u003e: Ca₂(Mg,Fe)₅Si₈O₂₂(OH)₂ (nephrite, actinolite–tremolite amphibole)\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMohs Hardness\u003c\/b\u003e: 6.5\u003cbr\u003e\u003cb\u003eTreatment\u003c\/b\u003e: Natural (untreated)\u003cbr\u003e\u003cb\u003eGrade\u003c\/b\u003e: Character Grade\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQuantity\u003c\/strong\u003e: 1 pc, or 1 kg bag (approx. 48 pieces)\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eWe do our best to buy quality products- although not every rock is the same.
