Our 24 Facet Vogel Crystal is natural Tibet Himalayan Quartz intentionally cut following Marcel Vogel's specific instruction. These Vogel Cut Crystals are clear double terminated crystal. Our cutter uses intuition with each crystal that is cut. The female end is approximately 52 degrees and the male end has been cut at approximately 58 degress. Because each crystal has its own frequency and unique qualities, we find that for optimization of the crystal, it's important to take this into account when cutting them. This is why our angles are approximate, as we work with each crystal to maximize its amplifying abilities! This process creates what we have found to be the most effective and powerfully amplifying Vogel Cut Crystal!
