Natural citrine?

0 votes

I have recently gotten into geology, so please forgive the lack of terminology.  Today I found a piece of what I believe to be citrine in my caliche driveway in the Austin, Texas area.  I read that natural citrine was uncommon, and that they do not have the reddish hues that mine has.  I have found various minerals in the driveway before, such as white quartz, chert/flint, and fossils.  The specimen is roughly 1" by 1.5" inches, and the colour varies from a very pale champagne yellow to a dark amber, forming on what I believe is limestone.  The crystals are the same height throughout, and are lighter on the edges than in the center.  Please give me your thoughts for the identification of this specimen.

I don't think this is citrine. They may be two different minerals. You can do a streak test.

From a visual perspective, it does have some indications as appearing as a quartz such as citrine. Can you post some additional pictures, especially towards the crystal faces to see if it can be positively identified by the presence of quartz crystal faces. It is possible to have a top crystallized layer of quartz and a bottom microcrystalline layer of agate/chalcedony.
