Very clear rock crystal point

A particularly clear, undamaged rock crystal point from Brazil. The base has been sawn so that the point stands freely and the termination faces upwards.

Inside are fine inclusions that shimmer in rainbow colors in the incident light. This iris effect is created by thin cleavage lamellae and tiny fluid inclusions in the quartz.

Rock crystal is pure SiO₂ in a trigonal crystal structure. The brilliance of this point varies depending on the light source, which is why the photo series shows the piece under several conditions.

A point for both daylight and display case presentation. Clear inner surfaces, complete termination, sawn standing base.
