One of the merchants' stones in ancient times it was believed to help accumulate and maintain wealth if kept in the safe or purse. Crystals of various rocks and minerals can crystalize either instantly or over a short or extended time like several thousand years depending on the mineral and the environment in which it occurs.Obsidian for instance forms crystals instantly but only while cooling down from liquid and molten volcanic material. Quartz is usually considered to be the parent mineral of obsidian so we can naturally assume that all varieties of quartz, crystalize or form the same way---wrong. The spring water clear quartz crystals form only in conditions, which are sterile of other outside forces like other minerals adjacent and no excessive pressure from overburden of overlying rock layers or by the slightest of movements. Other varieties of quartz require different environs to do their thing.
Some of the quartz family, such as amethyst, citrine, black, smoky, rose, green or any other shades of these colors form beautifully colored crystal clusters when forming in close proximity to other minerals or metals. This item is made of hexagonal crystals and clear quartz with green undertones.
