I have this pretty Uranium Glass trinket box/nut dish I would appreciate some help with. I have been told on several glass boards it is not American and I am out of resources to help I.D. It is It is 6 1/4" L x 3 1/2" W 2" T. It glows without a black light and has a polished rim. Ribbed sides and pressed glass with a pattern on bottom. I would like to know the possible maker or pointers and the era it was made. Thank you.
