I’d Miss Her Quartz, Too.For three years, I called it “your rock.” When Jo packed her quartz cluster, I realised how much of our life together had happened around it. Insights The Fire Quartz Fraud: Why Those Bright Red Crystals Might Be the Work of an Oven Natural fire quartz gets its red and gold from hematite and goethite left behind by iron-rich fluids; the factory version is clear quartz shattered by thermal shock, then filled with dye and epoxy resin under pressure.6 min · Treatments Insights The Auralite 23 Story: A Closer Look at Crystal Structure and Value Lab certificates read Natural Quartz, not a count of 23 minerals — what a real bead actually holds, and why the heavy inclusions make it crack more easily.6 min · Myths Insights The Silent Agreement of the Tanzanite Industry: Born Brown, Baked Blue Tanzanite is not a standalone mineral species; it is zoisite, and it leaves the mine a muddy yellow-brown. The royal blue comes from an industrial oven held at 450°C to 500°C. Heat treatment is a fully legal enhancement and the legal line is disclosure. Perfect cleavage is why ultrasonic and steam cleaning can split the stone.6 min · Treatment Insights The Hidden Chemistry of Bohemian Style: Why Turquoise and Malachite Hate the Shower Malachite is a copper carbonate mineral: sweat and body wash turn the glossy green foggy, dull and matte, and prolonged moisture can release trace copper ions.

Don’t Fall for the “Perfect” Trap Total perfection is often a sign of factory manufacturing. A few basic rules about how gems are sold.4 min · Buying Insights The Myth of Mohs Hardness: Why Your “Safe” Crystals Are Still Ruining in Water Mohs hardness does not tell you if a mineral is chemically stable.
