Herkimer Diamond in Matrix with Brass Support
Mineral Specimen with Custom Stand

Herkimer Diamond in Matrix with Brass Support

This item presents a natural specimen featuring a clear, double-terminated quartz crystal, commonly known as a Herkimer Diamond, embedded within its original rock matrix. The crystal itself appears relatively small, exhibiting classic natural facets and a high degree of transparency, suggesting good clarity. It is partially exposed from a recessed cavity within the host rock, which is irregular in shape and presents a rough, textured surface with varying shades of dark gray and brown, possibly indicating a shale or dolostone composition typical for Herkimer Diamond occurrences. The matrix shows evidence of natural fractures and uneven topography. The specimen is further accented by what appears to be a custom-fabricated support system, consisting of twisted brass wires or rods that are securely wrapped around or inserted into the matrix. These brass elements have a polished or slightly tarnished golden-brown patina, contrasting with the earthy tones of the rock. One brass piece is visible curving around the top left, and another extends from the bottom right, suggesting the item might be part of a larger display or mounted setting. The condition of the crystal appears excellent, with no visible chips or damage, while the matrix shows natural wear and geological characteristics. The craftsmanship of the brass supports suggests an intentional display piece, highlighting the natural beauty of the mineral specimen. The item captures the essence of a natural discovery enhanced by a minimalist, structural presentation, likely dating from the mid to late 20th century or more recently, reflecting a continued appreciation for raw mineral specimens.
