This engagement ring from the 1940's is beautiful! Constructed in platinum, the centerpiece of this ring is a .70 carat diamond, HI in color, and VS clarity. It is held in place by 12 "prongs". There is a cluster of three prongs for each "corner", giving this round diamond more of a cushion cut appearance. It is accented by a thin channel of small single cut diamonds that runs about a quarter of the way down the shank. A simple yet stunning piece of jewelry!
