Raised above a blackened band, the purple tanzanite reads like a jewel set into wrought iron, an aesthetic made for individuality over convention. It sits right at home among our gothic engagement rings and coffin-cut engagement rings, and the color story carries through our wider tanzanite engagement rings collection.\u003c\/p\u003e \u003cdiv class=\"ring-callout\"\u003e \u003cdiv class=\"ring-card\"\u003e \u003ch3\u003eThe engagement ring\u003c\/h3\u003e \u003cp\u003eHolds the 7 x 11 mm hexagon coffin-cut tanzanite (approx. 1.7 ct) in a setting flanked by simulated diamonds — the statement piece and focal point of the set.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"ring-card\"\u003e \u003ch3\u003eThe matching band\u003c\/h3\u003e \u003cp\u003eA slender blackened band designed to nest cleanly against the engagement ring, completing the two-piece bridal silhouette.

Simulated tanzanite gives you that rich, saturated hue with crisp, consistent color and brilliant sparkle, chosen to look its most dramatic framed by dark metal. December babies will love it as a birthstone; everyone else will simply love the color. To learn the lore behind the stone, our guide to tanzanite meaning is a beautiful place to start.\u003c\/p\u003e \u003ch2\u003eSimulated-diamond accents\u003c\/h2\u003e \u003cp\u003eSparkling simulated diamonds (crisp cubic zirconia) frame the setting, adding bright white fire that makes the purple read even deeper. It is a brilliant, budget-friendly way to layer in classic engagement-ring shimmer, and the contrast of white sparkle against blackened silver is what gives this set its avant-garde edge. Prefer a lab-grown diamond or moissanite accent instead? Message us — most of our designs can be upgraded.\u003c\/p\u003e \u003ch2\u003eThe black ruthenium finish\u003c\/h2\u003e \u003cp\u003eThe set is finished in black ruthenium, a rare precious metal from the platinum family, applied over solid 925 sterling silver. Ruthenium reads as a deep, smoky gunmetal — a rich blackened-silver tone rather than a flat, pure jet-black. That is the beauty of it: instead of looking painted-on, the finish carries genuine depth and an antique, gothic-vintage warmth, so every angular facet of the coffin cut holds a soft shadow. It lets a sterling silver ring read as something far darker and more mysterious. Curious about the metal? Read what is black ruthenium.\u003c\/p\u003e \u003ch2\u003eWhat it symbolizes\u003c\/h2\u003e \u003cp\u003ePurple has always been the color of royalty, wisdom and nobility, while black speaks to mystery, strength and devotion that endures. Together they make this coffin-cut set a fitting emblem for a love that is both powerful and unconventional.
