This 18K yellow gold Spinelli Kilcollin Janssen diamond link ring is crafted in the United States from four bands with varying widths in white and yellow gold. The fourth band is rhodium-plated sterling silver, encrusted with pavé-set white diamonds. This stackable ring is linked by yellow gold connectors, allowing it to be worn separately or stacked. Spinelli Kilcollin recognises the importance of Maslow's triangle of human needs, which is why it's dutifully created the Janssen ring which gives us four out of the five. Genius.
