Maybe a little incense "koro" that once upon a time had a lid?
The type of glass is called "goldstone" or "aventurine," and usually involves colloidal copper particles. Tricky to make. Fredric Schneider, in his book The Art of Japanese Cloisonne Enamel, discusses the various methods for creating goldstone enamels, noting that the most common creates an amber translucent enamel, hence the Japanese name "chakin-seki" or "tea gold."
It pretty much instantly brands a piece as Japanese, as the Chinese didn't produce goldstone enamels until probably around the 1960s, and the glitter in Chinese enamel is minute, more like dust.
