Lot of 22 vintage large and special Gray MOP / Mother of Pearl Buttons

Description

Presenting this great lot of antique/vintage Gray Mother of Pearl buttons.  This lot contains 22 buttons of which all are of fairly large to large size and several with carved features and other neat things.  The largest button measures 1 9/16 inches diameter and the smallest is 1 inch.
There are a few special buttons in this lot:
Thick Double Ring-  This is the largest of the lot and features a very thick button with two concentric circles carved into the face.  Very stout.
There is another pair of large 1 3/8 inches buttons that match and have a great rainbow sheen to them, you almost would think they were dyed abalone but who would do that.  Great pair.
The next button is definitely the most fancy as it is hand carved with a spiral sun ray design and has a white rhinestone mounted in the center.  Nicely polished button, very fancy.
The last button of note features an imbedded four-way brass box shank on the back.  Very old button.  Nice top face and large.
Most of the rest all have center hole mounts of either 2 or 4 holes.
Thanks for looking!
