This object is a vintage crystal "Corona" bowl designed by the renowned Swedish glass artist Lars Hellsten for the iconic Swedish glassworks company, Orrefors.
First introduced in 1978, the modernist Corona series features a signature thick-walled geometric cut with an eight-pointed scalloped rim. Hellsten famously drew his inspiration for this highly refractive design from the natural ring of light surrounding the moon. The collection became one of the company's best-selling lines before being discontinued in 2019.
These heavy art-glass pieces are typically signed by the artist or etched with the manufacturer's mark on the base.
