Four Rose Cut Diamonds: this ring is all about the rose cut Diamonds. The rose cut in Diamonds is a cut rarely seen these days, with its dome shape facetted all across the top, and its flat cut back. The modern cut, flat face surrounded by sloped facets, with a facetted pavilion below, is all about flash; it has been created over centuries with the help of ever better precision tools, and an ever expanding understanding of Diamond crystal structure and refractive possibilities.
But Diamond was a treasured gemstone long, long before the modern preoccupation with White Brilliance, treasured for its amazing hardness, durability and rarity, and for its perfect cleavage, which allowed the expert artisan to strike it just so, that it cleaved in perfectly straight planes, allowing it to gleam in light like no other gemstone.
By the late Middle Ages more sophisticated tools allowed the creation of cuts like the rose cut of the Diamonds in the above ring, to give more glint, more reflection of light.
