Enhydro Crystals are very clear crystals with moving air bubbles in water.

Mostly double terminated Diamond Quartz from Herkimer or Pakistan, calles Pakimer. The bubbles are also found in crystals from Zimbabwe called Shangaanquartz, Brandberg crystals from Namibia and also crystals from Brasil and Madagaskar.

I have the Diamond Quartz from Pakistan and Smokey Amethyst crystals from Brandberg region, Namibia with Enhydro bubbles. And sometimes the Shangaanquartz enhydro crystals
