NWA 2697 is a typical CV3 carbonaceous chondrite. The unpolished cut and unaltered back sides of this 129.4 gram half-stone are shown in Photos 1 and 2. Photo 3 offers a closer view of chondrules protruding from the latter. My reason for acquiring this piece was the large, 23 x 15 mm CAI seen in Photo 4 and also in Photo 5's close-up.

Just for fun, I thought I'd try to create a crossed-eye 3D image to be able to look down into the CAI's vug. Using a stereo zoom microscope and eyepiece projection, I was able to capture separate left and right eyepiece images that I cropped and assembled into Photo 6. While I wasn't able to stop the camera down enough to get everything uniformly in focus, it nonetheless gives a pretty good idea of the characteristics of this feature.

And for those that struggle with the crossed-eye method, Photo 7 offers a red-green anaglyph version that includes a second image inverted from the first - I find there are details in the inverted image that are not as evident in the normal one (and vice versa), so having both makes it easier to see additional minutiae.
