Inner World: Crystal with Skid Marks


This photograph (by a fellow gemologist, Laurianne Lognay) made me laugh. Snugged into a sapphire, this crystal made marks like an ice skater doing practice turns. It’s another example of how heat, pressure, and time create random, spontaneous patterns, colors, and moods that we have above ground. This crystal probably does not impact the brilliance of the stone and we can’t even see it without a microscope, but just knowing it’s there gives a gem identity and character.

This little capsule crystal and its attending lacy skid marks show us that at some point over thousands of years, this tiny crystal moved into position amidst the blue material, perhaps during a volcanic eruption. This itty bitty thing traveled a bit, looking for just the right spot to land. This little crystal is a good illustration of why we call these “inclusions” and not flaws. These inclusions are formed during Earth’s constant state of renewal and creation and they imply activity and energy in a now-still gem.

I hope you are all well. More sapphires are in! Bring me your jewelry and we can look for inclusions. It’s free and fun!
