6.5" Deep Purple Amethyst Cluster - Congo

About Congo Amethyst

Amethyst clusters from the Democratic Republic of the Congo are renowned for their exceptionally dark, saturated purple color and their impressively large, well-formed crystals. Many Congolese clusters display deep violet to almost inky tones, often with excellent luster and sharp crystal terminations. Compared to amethyst from other localities, Congo material tends to have thicker, more robust crystal points that grow densely together, giving these clusters a bold, architectural presence that is especially prized for display.

Commercially significant amethyst deposits in the Congo were first brought to wider international attention in the late 20th century, particularly during the 1990s and early 2000s, when large quantities of high-quality material entered the global mineral market. Most specimens are mined from quartz veins and geode pockets in metamorphic rocks in southern regions of the country, including areas near the Zambian border. Artisanal and small-scale mining remains common, with clusters carefully extracted by hand to preserve crystal integrity. Today, Congo amethyst clusters are considered some of the finest dark-colored amethyst available, valued by collectors for both their dramatic color and commanding crystal size.
