The lesser-known yellow hue of this popular gem gives diamond eternity rings a cheery burst of color. A 4-prong setting is a terrific option for offering extra security to these princess cut precious gems and highlighting your choice of precious metals. Each gem in a 4 prong setting is held in place by 4 individual pieces of precious metal not shared with another stone. Our eternity bands in immaculate .950 platinum can be set with your choice of stones, and we offer a vast assortment of carat weights in stock for most designs, in GH/I1, GH/SI, and FG/VS color/clarity grades.
