This Herkimer diamond crystal has the kind of internal contrast that immediately draws attention. The highly transparent quartz frames a dark geometric window through the centre of the crystal, creating an effect that stands out from typical clear Herkimers. Combined with attached secondary crystal growth, it has far more visual character than most specimens of this size.

Despite weighing just 1.6g, this is a genuine collector specimen rather than a standard thumbnail crystal. Sharp double terminated geometry, bright glassy lustre and excellent transparency give it strong display appeal from every angle. The attached growth adds depth and complexity, while the dark internal window creates a distinctive look that is instantly recognisable in a display cabinet or collection.
