Prism-Lite 1940s Diamond Ring in Bicolor Gold Illusion Mount

This ultra small ring (it's a size 2.5!) has a Prism Lite diamond prong set in a white gold illusion mount that's supported by a yellow gold band. The diamond is 3.75mm wide and weighs approximately 0.20ct. The illusion mount is designed to visually increase a diamond's perceived size by ensconcing it in white metal, blurring its optical boundaries. HISTORY LESSON: The Prism Lite diamond was a proprietary cut that was first trademarked in 1947. "‘Prism-Lite’ diamonds were in demand for their special brilliance achieved by ‘new scientific diamond cutting process’ and were purchased by jewelry stores & designers to set in their mounting." Metal: 14K Yellow Gold & 14K White Gold Main Stone: 1 Modified Round Brilliant Diamond (approx. 0.20ct, Prism Lite cut, 3.75mm) Ring Size: 2.5 (can be sized)
