From a classic locale, this is a lovely example of purple apatite. The crystals are aesthetically nestled in a vug of colorless, sparkling quartz crystals, to 2 mm in length. The apatite crystals exhibit glassy luster along with a pastel lilac color. Several of the translucent crystals, to .8 cm in length, are also doubly terminated. It is unusual to find specimens from here so nicely contrasted on matrix, and isolated form one another instead of the usual jumble.INTERESTING NOTE courtesy of WENDELL WILSON:I'm pleased that you are posting old labels with specimens. Your Hauck specimen # RH1-11 carries a label for H. W. Arndt. If you check the Label Archive you will find some background on him as follows: "Harold W. Arndt was President of the Delaware County, Pennsylvania Institute of Science, and was Curator of Minerals at Bryn Mawr College in Bryn Mawr, Pennsylvania from 1958 to 1989. He selected many of the finest minerals from the Vaux Collection for display in hall cases along the first and second floors of the Physics and Math wings of the Park Science Center. He also maintained a personal collection of minerals, as the labels shown here attest." That's all I know about him. I had two blank Arndt labels posted there, but didn't have one filled out in Arndt's handwriting. I hope you don't mind that I lifted your image and added it to Arndt's page. http://mineralogicalrecord.com... 5.2 x 4.2 x 4.0 cm
