"The Mariposa Monster" – Natural Gold in Milky Quartz

 * Origin: Mariposa County, California (Mother Lode District)

 * Total Weight: 53.7 grams

Specimen Overview

A substantial, heavy-in-hand display piece featuring thick, wiry, and crystalline gold crawling across a contrasting bright white quartz host rock. Unlike thin-veined or micro-gold specimens, "The Mariposa Monster" exhibits dense, cluster-like gold deposits with rich yellow luster, concentrated in thick ribbons across the crest and broad surfaces of the rock.

Key Highlights

 * High Gold Ratio: Roughly 25% of the total specimen's weight is solid native gold.

 * Exceptional Contrast: The brilliant gold and dark oxide veining pop dramatically against the clean white quartz background.

 * 360-Degree Appeal: Gold exposure is present across multiple faces, offering multiple mounting angles for display cases or mineral boxes.

 * Classic California Provenance: Sourced from historic Mariposa County, anchored at the southern terminus of California's famous Mother Lode belt.

Ideal piece for serious mineral collectors, high-grade gold display cases, or as a standalone centerpiece investment specimen. Comes with protective display packaging.
