• I prefer this gem be purchased loose only. If you would like me to set this gem for you, you will have to wait until I work through most of my current commissions. If you don't want to wait I'm happy to recommend one of jeweler peers to make a setting for it.
This is a very unique sapphire. I'm sure your wondering if it actually looks like the cover photo. In most lighting conditions you won't see this. The gem appears to have a deep blue core with yellow around the edges. Under a diffused LED lamp I was able to observe the rings without magnification if I looked directly perpendicular through the gems table. So yes, it is visible if you know how to observe it. I'm sure your also wondering what causes this color phenomena. The uncut gems twinning planes were parallel to the long axis and each twining plane had a different color. Dominant was of course blue, but where the blue ended, the yellow shone through. To put this in perspective, imagine multiple shards of colored glass stacked on top of each other and fused together. Each shard would correspond to a twinning plane. So if you looked through the top of the stack, the darkest color would naturally dominate, but if you looked sideways through the layers, you would see each layers individual color. In this sapphire, I oriented the table to be looking through the top of the stack of twinning planes, which is why the color mixture is so unusual. If I had oriented it parallel to the twining planes, the gem would have had stripes visible. Unfortunately, it wasn't a thick enough piece to warrant orienting it that way. Very cool though, right?!
In most lighting, you can expect to see a dominantly darker blue gem with yellow around the edges. There is an inclusion that is visible without magnification and a few smaller crystal inclusions that are visible only with magnification.
