Rare asteriated trapiche-like diamond
This photomicrograph shows a rare trapiche-like asteriated near-colorless diamond that possess some dark grey growth sectors forming an unusual Maltese cross-like pattern. This pattern is the result of …
Unusual photochromic faceted glass
Gemology is a discipline that often bring some amazing and unusual materials on the path of the curious gemologists. A while ago I had the chance to study a facetted man-made glass that shows a rarely encountered effect …
