An excellent specimen of purple Leucophosphite with gemmy crystals to 3mm. There are many good crystals and they exhibit some color change depending on your light source. Look at the prov. tab and you will see the old Bill Roberts tag, which states that it is one of the world's best (for that time). This is an ex. Mike Groben specimen with a date of 1976 on the tag. Since then, the Tip Top had been mined deeper and many more specimens were found in the early 1980's. Nonetheless, still a fantastic specimen. There is some minor Hureaulite crystals.
