Gemmy DT Calcite twin (ex Congressman John Culberson Coll.)

Item Description

An impressive, large, doubly terminated, twinned calcite with two strikingly different terminations. This gemmy and lustrous Elmwood has classic and desirable areas of rich golden-amber color to compliment the exceptional clarity of the large termination. The bit of sphalerite is a nice accent. The primary termination edge has a gentle bit of cleaving and trivial bruising is noted elsewhere. The sharks teeth terminations have only gentle bruising. Out-of-sight, the back is cleaved and broken. This is a highly representative large example of this classic form and famous locale. It is a fine display specimen that has long been in the mineral collection of John Culberson, a former Texas Congressmen in the US House of Representatives for the Houston area. He specialized in Elmwood minerals for several decades.
