You are clear quartz, the most common mineral on the Earth's surface and the most versatile. Quartz keeps time in watches, carries signals in electronics, and shows up in nearly every rock there is. Like you, it fits in anywhere and makes whatever it joins work better.

You are a natural amplifier: you make other people's ideas bigger and clearer, and you see the good in situations others have written off. Your transparency is your superpower. People trust you because there is no hidden agenda; what they see is exactly what they get.

Your strengths

  • Adaptable to any group or task
  • Generous with credit and energy
  • Clear thinker who cuts through noise

Watch out for

  • Spreads thin across too many projects
  • Can seem to lack a strong opinion
  • Absorbs other people's stress

About Quartz

Quartz is silicon dioxide, SiO2, one of the most abundant minerals in Earth's continental crust, crystallizing in the trigonal division of the hexagonal crystal system with a hardness of 7 that makes it a standard reference point on the Mohs scale. Its six-sided prismatic crystals, often terminated by pyramidal points, are among the most recognizable crystal shapes in mineralogy. Quartz occurs in nearly every rock type and geologic setting, from granite pegmatites to sedimentary sandstones to hydrothermal veins.

CleavageNone (rare parting on rhombohedral planes)
  • Quartz crystals vibrate at a precise, stable frequency when an electric current passes through them, a property called piezoelectricity that powers most quartz wristwatches.
  • Amethyst and citrine are chemically identical quartz, differing only in trace iron content and the type of natural or artificial irradiation each has experienced.
  • Sand on most of the world's beaches is dominated by quartz grains because the mineral resists weathering far longer than nearly any other rock-forming mineral.

How to tell real Quartz at a glance

  • Color: Colorless, White, Purple (amethyst), Yellow (citrine), Pink (rose), Brown/black (smoky). Look at a clean, dry surface in daylight. Color zoning, banding or spots are as diagnostic as the hue.
  • Luster: Vitreous, greasy on fracture surfaces. Fresh surfaces shine like glass; a dull surface usually means weathering, so chip or wet a corner.
  • Transparency: Transparent to translucent. Hold a thin edge up to a bright light and note whether light passes through.
  • Mohs hardness: 7. It scratches glass and a steel knife and cannot be scratched by a steel file.
