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 …
Cuboid diamond with a square heart
This photomicrograph shows a yellow cuboid diamond crystal with an unusual internal structure that possesses three whitish cuboid concentric layers as well as a strong inhomogeneous yellow color repartition, rarely encountered in …
Japanese flag spinels with an unusual red core
As a spinel lover a bit “geeky” I have hand-selected all my spinel samples under a microscope… here are some photomicrographs of what I have been amazed to find in some spinels from Myanmar: some rare and natural bicolor spinels with a …
Brown graining in a natural diamond

Covellite inclusions in a Pink Fire Quartz from Brazil
Here is a picture of a 3.89 ct “Pink Fire” Quartz sample that shows some Covellite inclusions spread out a ventura thorough the gem. Those crystallographically-oriented inclusions of Covellite appear dark green when seen under …
