1.96ct Halo Round Brilliant Cut Diamond Engagement Ring | Mark Broumand

The Round Brilliant Cut Diamond Engagement Ring

The round brilliant diamond engagement ring showcases a diamond that forever changed the jewelry industry with its beauty and brilliance.  In 1920, Marcel Tolkowsky authored a scientific publication, “Diamond Design” which became the diamond cutting bible in North America. Though formally educated as a physicist and mathematician, diamonds were in his blood.  Tolkowsky hailed from a family of diamond cutters from Antwerp, Belgium.

Diamond Cut Chart from Mark Broumand

By studying angles and light theory, Tolkowsky deduced that angles that were too deep or shallow would allow light rays or “shine” to escape through the bottom or sides of the diamond.  He calculated the best angles to maximize brilliance and optimize light reflection.  This is why modern rounds are so brilliant, and why the shape is often selected as accent stones and use in pavé settings.  Here are some of our favorites from Mark Broumand’s collection of round cut diamond rings.
