Earth's Gem Blueprint
Rarity: Earth's Limited Masterpieces
Gem-grade crystals comprise 0.3% of mined quartz. Prime veins deplete rapidly—2 tons ore yield 1ct vivid amethyst, with Afghanistan's kunzite reserves <0.5% global.
Color Genesis: Atomic Choreography
Trace elements interact with crystal lattices: radiation converts Fe²⁺ to Fe³⁺ for purple hues.
Only 1/100,000 crystals achieve uniform color.
Formation Paths: Earth's Four Forges
Hydrothermal processes form 90% of crystals (growing 1-10mm/day), while volcanic, metamorphic and cosmic impacts complete the quartet.
