While the manufacturer, country of origin, and purchase date are unknown, its transparency suggests it's likely a crystal glass trinket box or ashtray. In our home, it was used as a trinket box and displayed in a cabinet, but I am selling it now to declutter. There is a scratch-like mark in the center of the recessed area on the bottom, but otherwise, it is in very good condition. It has a considerable thickness, and the calculated arrangement of gold leaf and air bubbles trapped within the glass suggests it is likely a handmade piece by a glass artist. Size: Measured by hand Height: Approximately 5cm Width: Approximately 11cm To help you understand the size, I've placed a cork, 2.3cm in diameter and 4.5cm long, for comparison in the photos. Please note that this is a used item, so please refrain from purchasing if you are overly concerned about its condition. Thank you for looking.
