Rock crystal point, very clear to the base

A rock crystal point from Brazil, whose clarity is consistently maintained all the way down to the base of the column. This is an unusual characteristic, as most quartz points become cloudy or included towards the growth base.

Rock crystal is the purest variety of quartz (SiO₂). Clarity along the entire length of the column documents an exceptionally calm deposit genesis: without pressure peaks, without trace element shifts, without fluid inclusion generations during the entire growth process.

Such consistently clear points are classified as a premium category in the collector's trade. They are suitable not only for display in showcases but also as optical teaching objects for demonstrating light refraction.

The Brazilian deposits in Minas Gerais are worldwide the most productive source of clear quartz material. Within these deposits, consistently clear points are considered collector-relevant because they have also survived the recovery phase without micro-fractures.
