    Notes specific to this specimen: We are offering only a very limited number of specimens of this material. Most will be in the form of obelisks because they show off the mineralization patterns very clearly. At present we are offering only two different size obelisks. This is the larger one. The photos here are typical of this size. But you may not get this exact piece! Please keep in mind there is variation from piece to piece and the one you get may differ slightly from what is seen here. However, these photos are a good representation of what you can expect. Of course, as always, we guarantee your satisfaction or your money back.

  • Crystalized Welks (W4)

    Notes specific to this specimen: Fossil welks are much rarer than the clams found at Rucks Pit and most of them have no crystals. But, when you do find a nice crystal-line specimen, there’s nothing like it in the world! Here we have a nice natural window on the top side of the shell exposing beautiful gemmy dog-tooth calcite crystals on the inside. Also has a well-defined protoconch (the “tip” where the shell began). They don’t get much better than this!

  • Crystalized Welks (W3)

    Notes specific to this specimen: Fossil welks are much rarer than the clams found at Rucks Pit and most of them have no crystals. But, when you do find a nice crystal-line specimen, there’s nothing like it in the world! Here we have a nice matrix specimen with a natural opening on the side of the shell exposing gemmy dog-tooth calcite crystals. They don’t get much better than this!

  • Crystalized Welks (W2)

    Notes specific to this specimen: Fossil welks are much rarer than the clams found at Rucks Pit and most of them have no crystals.  But, when you do find a nice crystal-line specimen, there’s nothing like it in the world!  This is a single welk with a natural opening on its dorsal (top) allowing you to see the crystal lining of the shell and the gray sparite “floor” that was the sediment which partially filled the shell after the animal had died.  Very unusual.

  • Crystalized Welks (W1)

    Notes specific to this specimen: At our Rucks Pit site we sometimes come across fossil welks (conchs).  On rare occasions they may be crystalized.  This one has been cut in half to show the great crystal-lined hollow section inside.  Rare find.
