This exceptional specimen from San Pedro Mountain, New Mexico, is without question one of the most aesthetic and well-preserved rainbow garnet matrix pieces ever recovered from the locality. Measuring 34.2mm x 31.75mm x 21.55mm, the piece features a dramatically isolated main andradite crystal with stunningly sharp euhedral geometry. What sets this specimen apart is its unique spatial separation within the pocket—a rarity for crystals of this size from this locality, where intergrowth and pocket compaction often distort form and diminish visual impact.

The dominant crystal face radiates vivid emerald greens, layered with flashes of gold and subtle interference hues ranging from turquoise to violet, created by intense lamellar diffraction. These spectral bands ripple across the face with a silky metallic sheen, catching light in a way that makes the crystal appear to glow from within.

Nestled in a protective vug lined with vibrant green druzy garnets and flecks of white quartz, the presentation is almost sculptural. The matrix itself frames the main crystal perfectly, enhancing its visual isolation and further justifying its preservation in natural form—this would be a breathtaking faceting candidate, but its significance and aesthetics as a complete specimen elevate it beyond cutting.

Pieces like this are few and far between—capturing both the scientific interest of rare iridescence and the collector’s desire for sculptural elegance in matrix. A cornerstone example from the San Pedro Mtn. locality.
