Light passes cleanly through the stones, picking out their glassy clarity, and the larger sizes in this range carry real presence in the hand. The blue is cool and even, the look more gemstone than rough mineral.\u003c\/p\u003e\n\u003cp\u003eBlue Topaz is traditionally associated with calm, clear communication and settled thinking, and is often chosen by people who want a composed, articulate presence for speaking, writing or planning. It is commonly carried, kept at a desk, or held in quiet focus. Its clarity and colour also make it a handsome stone to display in the light.\u003c\/p\u003e\n\u003cp\u003eEach Blue Topaz stone differs slightly in tone and clarity, so no two are quite alike.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Properties\u003c\/strong\u003e\u003cbr\u003ePrimary Focus: Calm \u0026amp; Stress Relief\u003cbr\u003eSecondary Focus: Clarity \u0026amp; Focus\u003cbr\u003eChakra Association: Throat, Third Eye\u003cbr\u003eBirthstone: December\u003cbr\u003eZodiac Sign: Sagittarius, Virgo\u003cbr\u003eChinese Zodiac: Rabbit, Horse\u003cbr\u003eRuling Planet: Jupiter\u003cbr\u003eElements: Air, Water\u003cbr\u003eMohs Hardness: 8\u003cbr\u003eStone Family: Nesosilicate\u003cbr\u003eMaterial: Natural Blue Topaz\u003cbr\u003eOrigin: Brazil\u003cbr\u003eForm: Tumbled Stone\u003cbr\u003eFinish: Polished\u003cbr\u003eApproximate Size: 15-40 mm (0.6-1.6 inches)\u003cbr\u003eApproximate Weight: Single stone, 100 g, or 1 lb (454 g bulk quantity)\u003cbr\u003eListing: Single stone, 100 g, or 1 lb (454 g), variant selected at checkout\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGeological Information\u003c\/strong\u003e\u003cbr\u003eTopaz is an aluminium silicate fluoride of the orthorhombic system and one of the hardest silicate minerals at Mohs 8, with perfect basal cleavage. Natural colourless topaz is common, while the desirable blue is almost entirely the result of treatment. Virtually all commercial blue topaz, including this material, is produced by irradiation followed by heat treatment, a standard and regulated industry practice that yields stable, safe material; this treated origin is disclosed here. Topaz has been used in jewellery since antiquity, though the blue variety specifically is an enhancement product of the late 20th century. This material is sourced from Brazil, with further deposits in Sri Lanka and Nigeria.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuturaSol Standard\u003c\/strong\u003e\u003cbr\u003eEach natural stone is selected for its authenticity, geological integrity, and energetic clarity. Natural variations in colour, structure, inclusions, and surface features are inherent to geological materials and contribute to the individuality of each piece. Any known treatments, enhancements, stabilization, or man-made characteristics are clearly disclosed within the product information where applicable. Every piece is inspected and photographed to reflect its true character; however, lighting conditions, screen settings, and natural variation may cause slight differences in appearance.
