I have for offer this pair of mens cuff links.  I am not sure about the stone.  Glass I think.  Condition is a little rough.  Please see pics.  I normally do not sell things that are in this condition, but frankly, I have never seen anything like these before and though someone might like to add them to their collection.

The face of the cuff links are 25mm east to west and 11mm north to south.  The Amber is 10mm east to west and 6mm north to south.  They are not hallmarked, , weighing in at 6.2 grams. There are no problems other than ordinary and normal use marks. Comes from a clean, smoke-free home.   
 

These would be a compliment to any suit and would make a wonderful gift!
