This is a classic, large cabochon of excellent quality. There are no cracks or other imperfections. In addition to the dumorterite ridges, long tourmaline needles are clearly visible, as is a second quartz microcrystal within. It's difficult to see in the photo, but clearly visible in person. The video was shot in macro mode, in the shade, and under a lamp. The price is based on $30 per carat. Yes, the cabochon is quite expensive, but unique pieces don't come cheap!
