47 grams total of red coral the small single peice has been ground in half to show the color is all the way through i did the acetone test and had no dye . this coral was bought in japan many years ago. the original string was rotted so it is on fishing line for now. it was a bracelet originally . I tried to get the best pictures of the composition of the coral i could. i think these pieces could be worked into some very expensive jewelry
