Quartz

specimen number:

location:
Linda's Pocket, Jacksons Crossroads, Wilkes Co., Georgia, USA

description:
Attractive grouping of light purple glassy mostly gemmy crystals of quartz, this is the variety often called amethyst. In good condition. Crystallized naturally all around with no points of attachment.

The Jackson's Crossroads locality, situated in Wilkes County, Georgia, is a celebrated American mineral site famous for producing world-class, deep purple amethyst crystals. Geologically, the deposit is hosted within a highly weathered, hydrothermal quartz vein system cutting through late Precambrian to early Paleozoic granitic gneiss of the Piedmont geologic province. During ancient tectonic fracturing, low-temperature, silica-rich fluids filled open pockets within these veins, allowing well-formed amethyst prisms to grow, often exhibiting intense color zoning with distinct purple cores and colorless or smoky outer zones. Commercial mining and organized excavation for collector specimens at the site began in 1995 under private ownership and transitioned into a mechanized, open-pit quarry operation by the early 2000s. The mine has remained consistently active under controlled private leases, systematically extracting exceptional, highly lustrous crystal groups and faceting-grade gem material for the mineral market well into the 2020s.
