These 18K yellow gold Spinelli Kilcollin ruby, sapphire and diamond linked rings are crafted in the United States with four gold bands of varying widths. One ring is encrusted with pavé white diamonds and pink sapphires, with another boasting a parade of rubies. Rose gold connectors entwine the bands together, allowing the design to be worn across the fingers or stacked. We're not usually one to play games, but we do like to connect four where Spinelli Kilcollin rings are concerned. No one can say we don't know how to have fun.
