Quartz Var. Herkimer Diamond

Featuring a gemmy bed of glistening black druzy quartz crowned by a pristine Herkimer Diamond, this exceptional thumbnail specimen (23×21×14 mm) dazzles with unusually intense pyrobitumen (anthraxolite) inclusions. These rich hydrocarbon inclusions create a striking contrast against its glassy luster and sharp crystal faces. Although traces of hydrocarbon are typical at Middleville, the depth and even distribution of these inclusions are rare for this particular locality. Its sculptural form, combined with this locality’s fame, makes it a standout acquisition for any serious thumbnail mineral collector.
