clearly identified. The diamonds have a maximum diameter of 300 micrometers and appear to be of distinct morphologies common to previously described impact diamonds [2]. For example, our largest specimen is a platey diamond with very high relief and a clear-white color. The layered plates show distinct striations or fractures, which have been observed in earlier samples.
