Length: 6.25 & 8.5 mm
Width: 4.5 & 4.75 mm
Weight: 1.4 ct. total
Notes:

One contact twin and one penetration twinning quartz crystal specimen. A twin crystal (also called twinning) is recognized as two individual quartz crystals that have grown together to the extent that they have merged, but terminated separately. Twinned crystals may be contact twins or penetration twins. Contact twins typically have grown side to side and share a common facet point, see pictures below. With penetration twins the individual crystals grew point to point, as though they are passing through each other, pictured above. Sizes of specimens are:

  • Contact twin - 6.25x4.5x3.75 mm / .58 ct.
  • Penetration quartz - 8.5x4.75x4.5 mm / .86 ct.

Both Herkimers are well defined and water clear. It's a sweet pair of twin quartz crystal specimens.
