Inthe first instance nothing appears but the setting, the genuine diamond being abso-lutely transparent. The paste jewel, however, is quite visible, appearing as a dark spotin between the setting, showing the same opacity to the X ray as does also the lensof the eye-glass which is shown through the case. Just above the genuine diamondand the paste diamond rings is shown an opal ring which is somewhat transparent,although not so much so as the diamond. The marquis ring was also genuinediamonds, which appear in the picture as holes. Above the marquis ring is a pastejewel, and above that again a genuine. The difference is very apparent. This initself will prove the usefulness of the X ray for the determination of the genuinearticle, and our amateur friends
