Formed deep within igneous pegmatites, hydrothermal fluids deposited silicate quartz around growing tourmaline crystals, encapsulating dark linear rods and random criss-cross needle networks within transparent to light smoky crystal structure.\u003c\/p\u003e\n\n\u003cp\u003eCrafted into modern geometric bangle plate beads measuring approximately 12mm in length, this bracelet offers a comfortable 16-17cm wrist fit and displays crisp monochrome contrast. Each machine-cut plate is polished with comfortable beveled edges, allowing direct light transmission to highlight the internal black tourmaline inclusions against the clear quartz background.\u003c\/p\u003e\n\n\u003ch2 style=\"color: #2c5e5a; border-bottom: 2px solid #a3b899; padding-bottom: 5px; font-size: 1.4em;\"\u003e📊 Product Specifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x: auto; -webkit-overflow-scrolling: touch;\"\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 15px 0; text-align: left; font-size: 14px;\"\u003e\n    \u003ctr style=\"border-bottom: 1px solid #eee; background-color: #fcfdfe;\"\u003e\n        \u003ctd style=\"padding: 10px 8px; font-weight: bold; color: #2c5e5a; min-width: 120px;\"\u003eMineral Variety\u003c\/td\u003e\n        \u003ctd style=\"padding: 10px 8px;\"\u003e\u003cstrong\u003e100% Genuine Natural Black Tourmalinated Quartz (Black Rutilated Quartz)\u003c\/strong\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"border-bottom: 1px solid #eee; background-color: #fbfdfb;\"\u003e\n        \u003ctd style=\"padding: 10px 8px; font-weight: bold; color: #b85a5a;\"\u003eTreatment Status\u003c\/td\u003e\n        \u003ctd style=\"padding: 10px 8px;\"\u003e\n            \u003cstrong\u003e[100% Natural] Undyed \/ Unheated \/ No Dyeing (Earth-Mined Mineral Inclusions)\u003c\/strong\u003e\n        \u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n        \u003ctd style=\"padding: 10px 8px; font-weight: bold; color: #555;\"\u003eBead Dimension\u003c\/td\u003e\n        \u003ctd style=\"padding: 10px 8px;\"\u003eApprox. 12mm Plate Length (Geometric Bangle Cuff Profile)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n        \u003ctd style=\"padding: 10px 8px; font-weight: bold; color: #555;\"\u003eWrist Size Fit\u003c\/td\u003e\n        \u003ctd style=\"padding: 10px 8px;\"\u003eStandard 16-17cm Inner Circumference (Durable Stretch Cord)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n        \u003ctd style=\"padding: 10px 8px; font-weight: bold; color: #555;\"\u003eInclusion Profile\u003c\/td\u003e\n        \u003ctd style=\"padding: 10px 8px;\"\u003eNeedle-like Black Tourmaline Rods (Schorl) in Clear Quartz Matrix\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"border-bottom: 1px solid #eee;\"\u003e\n        \u003ctd style=\"padding: 10px 8px; font-weight: bold; color: #555;\"\u003eFinish \u0026amp; Contour\u003c\/td\u003e\n        \u003ctd style=\"padding: 10px 8px;\"\u003eMachine-Cut Beveled Flat Plate Profile \/ Glossy Surface Polish\u003c\/td\u003e\n    \u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch2 style=\"color: #2c5e5a; border-bottom: 2px solid #a3b899; padding-bottom: 5px; font-size: 1.4em;\"\u003eSelling Specifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eStandard Grade (Natural Polish Traits):\u003c\/strong\u003e\u003cbr\u003e\nDisplays rich black tourmaline needle density and clear quartz matrix.
