Each setting is handcrafted one by one and outfitted with a 3-cylinder prong as opposed to the standard 4. Fewer prongs and an aperture carved out of the bottom of each setting allow unparalleled light to flow through the piece and allow for more of each diamond to be visible. The piece is not rigid, it dangles freely with a stream of diamonds of varying sizes. .9 to .25 is the standard, but one can select any carat size.
