I know at first glance it looks similar to the above, but this is NOT from Utah. Rather, it is a Mexican topaz of unusual quality. Note the different style of the termination, more blocky and with a basal top instead of a pointed prismatic tip. This is old material from the 1960s or prior, and you do not see them in such quality, ever, for sale. I have seen BIGGER Tepetate topaz for sale, but not finer. This one is a JEWEL!
