A wonderful example of this popular US deposit, comprising sharply terminated and intensely saturated amethyst crystals with high transparency near the terminations on a bed of colorless quartz exhibiting sceptered growth.
While Silicon Oxide (SiO2) or quartz may be the second most common mineral present in the Earth’s crust, many rare and unusual varieties offer opportunities for collectors. From the royal purple and golden hues of amethyst and citrine, to the intense turquoise and apple green of chrysocolla and chrysoprase, quartz has an incredible spectrum of available colors. Rare and unusual crystal forms such as scepters, gwindels, faden, elestial and “spirit” quartzes create incredibly diverse aesthetics to enjoy. As a prime component within many of the great crystalline environments, quartz is also a frequent partner to and basis for other mineral growth. Classic combinations like smoky quartz and amazonite, fluorite on quartz, and spessartine garnet on smoky quartz offer fantastic contrasts of color and form.
