A flea market find from years ago. These earrings have .835 silver backs which are threaded and screw right into the back of the Ivorine or whatever it is called. I've never seen earrings like these. The stones- for lack of a better word - have a kind of diamond pattern crosshatching design within.
I know somebody will know the name of the material...
Thanks, CW friends!
Mmmm... Can't see well from the pics... Are you sure it is not ivory?
Love them :-)
kyra - no, I don't think these are ivory. If you look at the third photo enlarged, you can see the diamond pattern on the edges of the earrings.
So, mystery too for me :-(
kyra - I changed one of the photos - maybe this one is better (orange Tupperware).
Thank you! This pattern is really puzzling...
Too regular for ivory, the other mystery is why the other earring doesn't have same!
kyra - the other earring does have pattern lines, but they look somewhat different.
Maybe these ARE ivory and those lines are crosshatching.

"Schreger Lines (Angles)
The key feature to identifying elephant ivory is a unique pattern of crosshatching that appear in cross sections of elephant tusk. These lines, actually rows of microscopic tubes, are known as Schreger Lines; where they cross form Schreger Angles. Schreger Lines have never been duplicated in artificial plastics or resins. Schreger Lines must be present to qualify a pieces as elephant ivory. The lines are most easily seen in the bases of figures and anywhere cuts are made at right angles to the grain.
Schreger Angles are used to establish whether ivory is from present day elephants or extinct elephants such as mammoths. This is an important distinction because the sale of extinct elephant ivory is basically unrestricted while the sale of present day elephant ivory is tightly regulated. Schreger Angles of less than 90° indicate mammoth ivory; angles greater than 115° indicate elephant ivory. Use the outer Schreger Angles (closest to the outside edge) only for this test. Do not use Schreger Angles in the center of the tusk. Measure at least five angles to get a true average."
It's also hard for me to see them well...maybe petrified coral?
I really wish I could say educated things about your pieces but you have the best eye!! Your knowledge is always informative and your patience to sort through is over the top. Those bags near the cash register...only you girl!!
From the photos, and from everything I've read, if it has cross-hatching, it's ivory.
They are definately ivory. Nice catch
THANKS, all~! I was suspicious that these might be ivory, but needed to be sure.
