From the text:
As for the third chest, it was only about a fourth full, but the stones were all picked ones; none less than twenty carats, and some of them as large as pigeon-eggs. A good many of these bigger ones, however, we could see by holding them up to the light, were a little yellow, โoff coloured,โ as they call it at Kimberley.
