Chairman's Notes

As is the case with all coloured stones, the colour is paramount, and the most important quality factor. In addition to this, the most valued star stones display strong and straight white rays, with a centred star that floats smoothly across the surface with the right light source. Only superior cutting, as exhibited with this piece, will release a gem’s beauty, with the finest star stones cut and polished as symmetrical and well-balanced cabochons.
