Crystals for Cancer

The best crystals for Cancer are Ammonite, Calcite (Coloured Varieties) and Chrysoprase, the first of 22 stones tradition ties to the sign. Each entry names the mineral it actually is, the physical test that separates a real one from a treated lookalike, and what the stone means for a Cancer chart.

• Ammonite3.5-4.5 Mohs · organic · root, crownA cephalopod that built its shell in a logarithmic spiral, lived in the last chamber and used the rest for buoyancy, then went extinct with…
• Calcite (Coloured Varieties)3 Mohs · carbonate · sacral, solar-plexus, heartThe most abundant carbonate on earth in its decorative dress, orange and honey from Mexico, mint green from Pakistan, blue from Madagascar,…
• Chrysoprase6-7 Mohs · chalcedony · heartThe only chalcedony coloured green by nickel rather than by iron or chromium, which is why the tone is unmistakably apple rather than fores…
• Emerald7.5-8 Mohs · silicate · heartBeryl coloured by chromium, and one of the four traditional precious stones, mined at Cleopatra's Egyptian workings, then in vast quantity …
• Magnesite3.5-4.5 Mohs · carbonate · crown, heartMagnesium carbonate, mostly an industrial refractory mineral, and the second great blank canvas of the crystal trade. Where howlite has bla…
• Milky Quartz7 Mohs · quartz · crownThe plain white filler of a thousand mineral veins, quartz clouded to opacity by trapped water and gas. It is the most abundant gemmy rock …
• Moonstone6-6.5 Mohs · feldspar · sacral, third-eye, crownPotassium feldspar that unmixed into microscopically thin alternating layers as it cooled, scattering light into a floating blue-white glow…
• Morganite7.5-8 Mohs · silicate · heartPink beryl, named in 1911 for J.P. Morgan, who was buying minerals at a scale that got things named after him. Manganese does the colouring…
• Moss Agate6.5-7 Mohs · chalcedony · heart, rootChalcedony that trapped mineral filaments as it formed, producing something that looks convincingly like vegetation and is entirely inorgan…
• Ocean Jasper6.5-7 Mohs · chalcedony · heart, throatNot really a jasper: an orbicular rhyolite from the north-west Madagascan coast in which silica-rich fluids grew spherulites and then repla…
• Opalite5.5-6 Mohs · man-made · crown, third-eyeGlass. Not opal, not moonstone, not a mineral of any kind, an opalescent art glass produced in quantity and sold under a name engineered to…
• Optical Calcite3 Mohs · carbonate · crown, third-eyeClear calcite that splits light into two rays, so text read through it appears twice, the mineral that let nineteenth-century physicists pr…
• Orthoceras3-4 Mohs · organic · root, third-eyeStraight-shelled nautiloids from Devonian and Ordovician seas, quarried by the tonne in the Erfoud region of Morocco and cut into slabs, sp…
• Phantom Quartz7 Mohs · quartz · third-eye, crownA crystal that stopped growing, got dusted with chlorite or iron, and then resumed, leaving its own younger outline sealed inside like a fo…
• Rainbow Moonstone6-6.5 Mohs · feldspar · third-eye, crown, sacralThe best-selling moonstone in the world is not moonstone: it is white labradorite from India and Madagascar, flashing blue by a different o…
• Rhodochrosite3.5-4 Mohs · carbonate · heart, solar-plexusManganese carbonate, banded pink and white where it grew as stalactites in old Inca silver workings at Capillitas in Argentina, and blood-r…
• Rose Quartz7 Mohs · quartz · heartPink from vanishingly small fibres of a dumortierite-like mineral suspended in the quartz, the colour is a structural accident, not a dye. …
• Ruby in Zoisite6-9 Mohs · rock (aggregate) · heart, rootRuby crystals grown inside green zoisite, found in 1949 in the Longido district of Tanzania and named anyolite from the Maasai word for gre…
• Satin Spar2 Mohs · sulfate · crownThe white silky towers everyone owns and everyone calls selenite. It is fibrous gypsum, same mineral, different habit, mined mostly in Moro…
• Selenite2 Mohs · sulfate · crown, third-eyeTransparent gypsum, soft enough to mark with a fingernail and soluble enough to ruin in a rainstorm, the mineral kingdom's tissue paper. Me…
• Shungite3.5-4 Mohs · organic · rootA roughly two-billion-year-old carbon rock from the Lake Onega region of Karelia, containing genuine fullerenes, the only significant natur…
• Synthetic Opal4.5-6.5 Mohs · man-made · crown, heartReal opal chemistry assembled by people, silica microspheres stacked into the same diffraction lattice nature builds, then consolidated, of…
