Possibly Ivory, Soapstone, Resin,

Dear Jonathan,
These pieces look all quite late to me; If thre are ivory pieces there you should not sell them because of CITES regulation. If you want to be sure please send pictures of each piece to me in daylight. They really need to be sharp. No full sunlight please. Now I evaluate only decorative value to the pieces. They are all Chinese / Hong Kong en seams to be after 1960.
Dear Jonathan, I see Bone ( no 1 ) and ivory pieces Picture 2 , 4 en I believe 5. Picture three shows clear schreger lines at the time ( crossed lines ). Look for that. If you vannot find any look for dark spots. Dark spots are dry bloodvessels in bone. Ivory does not have bloodvessels, its line nail. I believe the Ivory pieces are of questionable date. Could be 1940 could be later.If you would like to sell them a auction house would or would not accept them I feel. Be aware of that. Broken or missing pieces has big impact on the value.
