This is, to me, a very unique specimen featuring the largest, well-crystallized, 3-dimensional spinel twin gold on matrix that I have ever seen available. This is not a flattenned crystalline gold as with Eagle's Nest material and it is not a typical octahedral crystal or cluster of such as some Mockingbird material occurs. Rather, this is a single thick, euhedral crystal, fully 3.5 cm tip-to-tip, just so nicely perched on a well-trimmed matrix. This crystal has a natural patina as the enclosing quartz was removed with physical means instead of the less elegant but easier method of hydrofluoric acid. It is complete-all-around and is equally fine from the other side.
