standard round brilliant cut from pale Afghan rough that originally a bi-color
Standard round brilliant cut from Afghan rough that was originally a bi-color.
For a while I was able to deal with a source of tourmaline rough that had a direct connection for Afghanistan material. I not only bought individual stones, as I usually do, but also a few lots. The pastel pink and blue rounds pictured above are examples of a couple of rounds of purchases of lots threw that source. I titled this post as a broken embrace, because the tourmaline rough, as found in Afghanistan was a bi-color. There is always potential breakage at the junction of colors in a bi-color because of stress in the crystal. In this case, even with such pale colors, the stress was too much to hold the crystals together and I only go one bi-color out of the lots. The crystal was pure and had the lowest level of tone that I found in the lots. I have describe that bi-color in a previous post as almost colorless and an example of IceT.
