Peridot "lily pad" inclusion

KurtS · **Posted:** Thu Jul 10, 2008 12:33 am

Here's a stone I've tentatively identified as Peridot, due to its color, high birefringence, and the "lily pad" inclusion, which isn't visible here. I found it rather tricky to light both the facets and the inclusion. I really like the "sleepy" nature of this stone, which I attribute to numerous silky inclusions seen under the scope. Click on the photo to see doubling of the facets.

Here's a detail of the "lily pad" inclusion (arrow).

Here's one I took recently, also showing the doubling caused by the high birefringence:

I saw those at the Gemology project--very instructive shots!

Here's one more Peridot, showing a small inclusion in the right center, as well as the characteristic optical doubling of facets. This was shot using two lights with different color temperatures. While not totally accurate in terms of color, I like the effect.
